Navigating Energy Transition: Comprehensive Solutions for Textile Players in the Pursuit of Sustainability

Posted on by Thermaxqaz

In the vibrant tapestry of India’s economy, the textile industry emerges as a potent force, weaving not just fabric but also millions of livelihoods. More so, India has a 4% share of the global trade in textiles and apparel. Yet, amidst this growth, there is a silent concern – the conventional methods and materials integral to the textile processes that often impact the environment negatively.

From dyeing practices to energy-intensive operations like spinning and weaving, the industry’s ecological footprint demands reconsideration. As India progresses on its sustainable endeavours, it is a rallying call for textile players to steer their course towards cleaner, more responsible technologies. Thermax stands poised to facilitate this transformation with its repertoire of solutions, services, and custom-tailored innovations designed to steer the textile sector towards a greener future.

Water treatment: The key to water conservation

Posted on by Thermaxqaz

Have you ever wondered why Earth is called the blue planet? It’s because water covers about 70% of its surface. Considering this amount of water available, it seems obvious that it is abundant. However, 97% of the Earth’s water is saline consisting of 1,335 million km3, and 2% is frozen freshwater locked up in glaciers, polar ice caps, soil etc. and is unavailable for use. As a result, there is only 2,04,000 km3 of freshwater available for consumption, which is about 0.5 to 1% of the total freshwater available. Water is mainly used for agriculture, industry, and domestic purposes.

IGlobally, freshwater withdrawals in 2017 totalled 3,880 km3, of which India drew 647 km3. It is estimated that industrial activities require between 2 and 20% of the total amount of water. According to one of the references, India uses 14 km3 of water for industrial purposes, 48 km3 for domestic, and 586 km3 for agricultural purposes. The demand for water in agriculture exceeds 80% of total consumption; therefore, it is crucial to increase water efficiency. As agriculture runoff is a non-point source, its treatment and reuse are difficult. Sewage can be reused, and it can become one of the sources of water. However, in our country, only 1/3rd of sewage is treated. The discharge of untreated wastewater pollutes natural water bodies. Due to the growing demand and limited availability of water, India, China, and a few European and African countries are expected to experience water scarcity by 2025.

In case of scarcity, water supply to industries would be restricted. Considering the rising water demand in India, an additional 7 km3 of water could be made available even if 50% of wastewater is recycled by industries. This volume is equivalent to more than five years of water requirement of New Delhi.

Lack of uniform distribution of water resources across the globe, erratic climate changes, and poor water conservation and management strategies are major causes of water scarcity. It is expected that water scarcity can be physical, where there is not enough water available to meet the demand, or economic, where there is enough water available but not the proper means to produce desirable water quality. Hence, industries must achieve and sustain wastewater recycling to the maximum extent possible. Ideally, Zero Liquid Discharge (ZLD) of all liquid streams should be targeted. There are many factors affecting the effluent treatment process, such as changing effluent quality and quantity, different combinations of constituents from various manufacturing processes, and uncertainty about the effectiveness of conventional treatments.

The ongoing technological advancements and augmentation in manufacturing processes are changing the composition of wastewater. Thus, efficient industrial wastewater treatment plays a critical role in water quality management. It is possible to treat a wide range of effluents by integrating conventional and new technologies. For example, conventional treatment can reduce organic constituents and inorganic solids from coke oven wastewater, whereas novel adsorbents can reduce source-specific constituents. Thus, such hybrid treatment would help to recycle tough-to-treat wastewaters.

ZLD is considered an emerging alternative to reduce the water demand of the industry. As the name indicates, ‘Zero Liquid Discharge’ eliminates all liquid waste from the system. In ZLD, wastewater is treated, reused, and the residues are concentrated and disposed of in solid form. Bioprocesses and membrane filtration-based solutions are adopted for the treatment of industrial wastewater. Thermal technologies like multi effect evaporator (MEE) and mechanical vapour recompression (MVR) are used to concentrate inorganic constituents. This helps the industries to maximise water recovery.

There are a multitude of measures that citizens, industries, and authorities can adopt to bring about a notable change in the water conservation scenario. The first step, however, is to acknowledge that water is a valuable resource and implement water reuse on an organisational as well as individual level. Every drop counts!

Clean Air

Posted on by Thermaxqaz

Cleaner Technologies for a Greener Tomorrow

Air is vital for the survival of most organisms on earth. With the advancement in technology and the industrial revolution, major air pollutants have been released into the air, causing widespread pollution. High levels of pollution can increase the risk of respiratory infections, among other adverse health outcomes. A major example of the ill effects of air pollution is the ozone hole in the atmosphere formed due to the release of harmful chemicals called chlorofluorocarbons which causes ozone degradation on an unprecedented scale. Such events serve as a reminder of the importance of maintaining strict parameters to ensure that air pollution is minimised.

 

Types of Air Pollutants

Any material which, when released into the air, can cause adverse effects on humans and the ecosystem are termed air pollutants. Pollutants can be suspended solid particles, liquid droplets or gases. Pollutants are classified as primary or secondary. Primary pollutants are usually produced by processes such as ash from a volcanic eruption or carbon monoxide emitted from vehicles. Secondary pollutants, on the other hand, are not directly emitted. When two or more primary pollutants react with each other, they often give rise to more harmful secondary pollutants. Ground-level ozone is a prominent example of a secondary pollutant. 

Most air pollutants are anthropogenic i.e. of human origin. The most prominent pollutants include:

  • Carbon dioxide (CO2): Described as ‘the leading pollutant’ globally due to its capabilities as a greenhouse gas, air pollution is often measured with respect to net carbon emission. Billions of tonnes of CO2 are emitted annually, leading to an overall rise in global temperature and resulting in drastic weather conditions and a rapid rise in sea levels across the world.
  • Sulphur oxides (SOx): Most common pollutant belonging to the sulphur oxide family is sulphur dioxide (SO2). SO2 is naturally produced in volcanoes but is mainly emitted in various industrial processes. Coal and petroleum also contain sulphur compounds in various forms, and their combustion releases sulphur dioxide as a major pollutant. Further oxidation of SO2 can occur but only in the presence of a catalyst such as NO2, giving rise to sulphuric acid (H2SO4), which then forms acid rain. This is one of the causes for concern over the environmental impact of the use of these fuels as power sources.
  • Nitrogen oxides (NOx): Nitrogen oxides, most commonly nitrogen dioxide, are produced by high-temperature combustion in industries and modern car engines fitted with internal combustion systems. They are responsible for smog formation, which can be seen as a brown haze above cities reducing visibility to mere metres and increasing the chances of accidents.
  • Carbon monoxide (CO): Carbon monoxide is a highly toxic gas formed mainly by the combustion of fossil fuels such as natural gas, coal or wood. Vehicular exhaust thus contributes to the majority of carbon monoxide released into the atmosphere. It is also responsible for smog formation, which is known to cause multiple lung disorders and disruptions in the ecosystem as well.
  • Volatile Organic Compounds (VOC): VOCs are a well-known group of outdoor air pollutants. They are categorised as either methane (CH4) or non-methane (NMVOCs). Methane is an extremely efficient greenhouse gas which contributes to global warming. Other hydrocarbon VOCs are also significant greenhouse gases because of their role in creating ozone and prolonging the life of methane in the atmosphere.
  • Particulate matter: Aerosols and Particulate Matter (PM) are mostly produced by human activities such as the combustion of fossil fuels in automobiles, power plants, and numerous industrial processes. An increase in the levels of fine particles in the air leads to health hazards such as heart disease, more commonly occurring along with altered lung function and lung cancer. Particulates are related to respiratory infections and can seriously affect those with conditions like asthma.

 

Control of Air Pollution

Thermax has a long and distinguished history of providing environment-friendly solutions that help their customers to protect the environment while not compromising on their production efficiency. Since 1980, the Air Pollution Control arm of Thermax has grown to become a globally renowned brand for industries concerned with the control of particulate and gaseous emissions. Thermax delivers the best solutions to its customers while making use of its extensive engagement with diverse sectors and collaborations with major companies in the field. Thermax’s solution offers double benefits to process-driven industries like cement, steel, aluminium, copper, etc., helping them recover products at various stages of plant processes and also comply with stipulated emission norms.

  • Electrostatic Precipitator (ESP) is a flagship product of Thermax, working successfully across heavy polluting sectors, including power, cement, steel, non-ferrous metallurgical and fertilisers. The Electrostatic Precipitators (ESPs) come in two variants, dry ESP and wet ESP. The former is used on hot process exhaust (50 – 450°C) that operates above the dew point of the gas stream, while wet ESPs are part of a special application system and are used for filtering wet sticky, tarry and oily particulate matter. It is capable of capturing 100+ types of particulate matter from 1 micron to 1000 microns and can filter out harmful particles such as coal as well as 50+ types of biomass fuel from being emitted into the environment.
  • Pulse Jet Bag Filters – Bag filters offered by Thermax are typically of two distinct types – pulse jet bag filters being one of them. Thermax has patented highly technical and innovative pulse jet bag filters. Pulse jet bag filters with filter bags of length more than 6 metre are equipped with unique pulsing systems where bags are cleaned sequentially, even when the dust-laden gas is filtered. The cleaning is controlled automatically by a sequence controller. This operates the assembly of solenoid and pulse valves which direct the airflow into manifolds. Pulse jet bag filters are thus designed to achieve maximum cleaning efficiency.
  • Reverse Air Bag Houses – Thermax has developed several fabric filtration systems, with one of the most significant milestones being the installation of reverse air bag houses for cement kiln and sponge iron industries. In reverse air bag houses, the bags are fastened onto a cell plate at the bottom of the baghouse and suspended from an adjustable hanger frame at the top. Dirty gas flow normally enters the baghouse and passes through the bag from the inside, and the dust collects on the inside of the bags. 

Reverse air bag houses are compartmentalised to allow continuous operation. Thermax’s RABH has four or more independent modules – the modules are set in pairs when the gas flows are on the higher side. Each module can be isolated for inspection or maintenance by closing the inlet, outlet and reverse air damper while other modules are in operation. The flow of the dirty gas helps maintain the shape of the bag. However, to prevent total collapse and during the cleaning cycle, rigid rings are sewn into the bags at intervals. RABH are an innovative solution to help get rid of air pollutants.

  • ComboFilter – ComboFilter is the latest innovation in air pollution control technology that has been developed by Thermax after extensive research and development. ComboFilter is designed to help old pollution control equipment meet stringent environmental norms. A ComboFilter is a combination of an Electrostatic Precipitator (ESP) and a Bag House Filter (BH), which offers the advantages of both systems. ComboFilter offers the benefit of easy coagulation and precipitation of particulate matter through electrostatic precipitation and further reduction of emission through the usage of filter media. ComboFilter is the ultimate solution to comply with the revised stringent emission norms by retrofitting a few fields of the ESP to BH.
  • Flue Gas Desulphurisation (FGD) – FGD is a process that can achieve SO2 removal with more than 97% capture efficiency. A Flue Gas Desulphurisation (FGD) system is majorly available in three variants – Wet Flue Gas Desulphurisation (WFGD), Spray Dryer Absorber (SDA) and Dry Sorbent Injection (DSI), each with distinctive capabilities for emission control. The systems use alkali reagents for sulphur dioxide (SO2) removal. In addition to SO2 removal, these systems also treat HCl, HF, SO3 and fly ash. 
  • Scrubbers – A scrubber is a versatile system capable of handling a wide range of gas volumes for scrubbing the acidic/alkaline nature of gases, hygroscopic, adhesive and explosive materials. It is designed for both particulates as well as gaseous pollution abatement. The variants available for particulate scrubbing are venturi and cyclonic. 

Thermax believes that clean air, free of pollution, can be achieved only by working together and cooperating to create a sustainable ecosystem where technology can peacefully co-exist with nature. With its technologies and innovations in the field of energy and environment, Thermax empowers the customer to contribute to the development of a better future. Thermax’s efficient and stringent pollution control solutions ensure that the invaluable natural resource – air, remains free from pollution.

Let’s together save #OurPlanetOurHome

Earth is home to millions of species of organisms with each distinctly different from the other. Humans are a part of this wonderful family and are the most advanced species to walk on the planet. In ancient times humans worshipped nature and lived in harmony with the environment. But with the advent of the industrial revolution in the 19th century, this harmony was destroyed. Rampant pollution and exploitation of natural resources for profit maximisation began. Today we are staring at a future of record global warming, climate change and a catastrophic rise in sea levels. All-time high temperatures across the globe, waning polar ice cover and unequal rainfall patterns are the consequences of centuries of over-exploitation. If we do nothing to stop this change, we can lose the earth as our home.

In order to save millions of lives from an unprecedented climate crisis, various climate action plans have been formulated and climate conventions have been held. India has taken a lead role in these climate summits and has committed to achieving net-zero carbon emissions by the year 2070. This includes developing sustainable alternatives to current options in many critical sectors like power and reducing vehicular and industrial emissions which cause rampant pollution.

Developing solutions to protect the environment

To save the Earth for future generations, it is thus important for us to take up the responsibility to restore the planet through developing eco-friendly technologies as well as growing focus on reducing the exploitation of natural resources and controlling environmental pollution. India on its part has undertaken several high-level projects to reduce its carbon footprint in addition to developing safeguards to protect the environment. For example, replacing coal, which contributes to more than 70% of all Indian electricity generation with solar power. Many industries are also aligning themselves to the Sustainable Development Goals to develop without harming the environment. Thermax is focussed on bringing sustainability to the entire production process – right from sourcing, manufacturing, supply chain management, distribution and consumption.

Thermax’s offerings in waste heat recovery, biofuels, solar, Bio CNG, waste to energy etc., show its commitment to protecting the environment. In addition to contributing to global sustainability, Thermax’s solutions also strive to contribute substantially to the global priority areas of energy conservation, environment protection and enrichment of society.

Controlling Air Pollution
Air pollution is a major contributor to environmental pollution. Harmful gases emitted by vehicles and heavy industries on a regular basis cause global warming and lead to environmental pollution. Thermax offers multifold benefits to industries like cement, steel, aluminium, copper, etc., helping them recover products at various stages of plant processes and also comply with stipulated emission norms.
 
Electrostatic Precipitator (ESP) is a flagship product of Thermax working successfully across heavy polluting sectors including power, cement, steel, non-ferrous metallurgical and fertilisers. The Electrostatic Precipitators (ESPs) come in two variants, Dry ESP and Wet ESP. The former is used on hot process exhaust (50℃ – 450℃) that operates above the dew point of the gas stream while wet ESPs are part of a special application system and are used for filtering wet, sticky, tarry and oily particulate matter. It is capable of capturing 100+ types of particulate matter from 1 micron to 1000 microns and can filter out harmful particles such as coal as well as 50+ types of biomass fuel from being emitted into the environment.
 
Scrubbers- A scrubber is a versatile system capable of handling a wide range of gas volumes for scrubbing the acidic/alkaline nature of gases, hygroscopic, adhesive and explosive materials. It is designed for both particulates as well as gaseous pollution abatement. The variants available for particulate scrubbing are venturi and cyclonic.
 
Bag Filters- These come in two variants – the Pulse Jet Bag Filter and Reverse Air Bag House with each involved in particulate emission control or product recovery in a boiler, furnace, kiln or mills. It is capable of handling 100+ types of particulate matter and is highly efficient in removing particulate matter from emissions.

Water Pollution and Effluent Control
Thermax is one of the leading companies in providing water and waste solutions for the past four decades to help several industries reduce fresh water consumption as well as reuse and recycling of wastewater. Thermax offers a wide range of sustainable options to control industrial water pollution as well as providing solutions to achieve Zero Liquid Discharge.

Zero Liquid Discharge – Zero Liquid Discharge is a wastewater recycling process used to limit liquid waste by removing all waste liquids and completely reusing the wastewater which is normally dumped in water bodies polluting them. Thermax has erected several cost-effective systems to recycle wastewater and provides Zero Liquid Discharge solutions for various industrial sectors. ZLD can be used by thermal technologies such as evaporators like Multi Effect Evaporation (MEE). Although short-term costs of production increase with the ZLD system but the long-term benefits far outweigh conventional options.
Wastewater Treatment -Thermax offers customised as well as standardised wastewater treatment plants for industries, housing societies, and commercial complexes. These solutions can greatly reduce the emissions of an industrial plant in addition to increasing the longevity of existing systems. Wastewater contains industrial wastewater and domestic sewage. Wastewater treatment plants are designed using a combination of physical, chemical and biological processes, so that treated water could be discharged into the environment or reused further.

Desalination- We have a large deposit of virtually unusable water in the form of oceans that cover over three-fourths of the planet because of a high amount of suspended solids like sodium chloride (table salt) which makes it unfit for use – both for drinking as well as for commercial purposes. Desalination involves the removal of these dissolved minerals from seawater and brackish water (a mixture of fresh water and ocean water) to reduce the strain on freshwater resources like rivers and streams. Desalination has grown to be accepted by many major industries, which are looking to invest in desalination plants to reduce their dependence on freshwater resources for the operation of their plants.

Solar Energy Solutions

With solar PV installations spread across industries and geographies, Thermax is helping customers generate green energy and minimise electricity costs. Thermax has a wide range of solar options for its customers to choose from –

Solar Rooftop – Solar energy offers an excellent return on investment while utilising the rooftop space of the customer’s facility. Solar rooftop solutions can generate free electricity for more than 25 years, resulting in substantial huge savings and reducing the carbon footprint as well.

Waste to Energy Technologies

‘Waste to wealth’ is the main principle of sustainable development and generation of sustainable energy. Waste products such as biomass play a very important role as substrates to be used in energy generation. Biomass and ‘waste to energy generation’ are some of the most promising technologies to look forward to trying and developing independence from fossil fuels. Some of these are listed below:

Biomass-Powered Boilers – Biomass is renewable organic material that comes from plants and animals and is a major producer of methane gas. These are produced in large quantities and are mostly dumped in landfills wasting their potential for energy generation. Thermax offers several advanced technologies to tap into this potential for providing renewable energy.

Thermax has developed boilers with the capability of using biomass as the source of fuel instead of fossil fuels like coal without compromising on the quality of their products. These boilers have various benefits including fuel flexibility, low maintenance, high efficiency, high availability, and reliability.

Waste To Energy – A waste-to-energy plant is a type of advanced waste management facility that combusts waste to produce electricity. This type of power plant is sometimes called a trash-to-energy, municipal waste incineration, energy recovery, or resource recovery plant.

Spent Wash (Vinasse) Fired Boiler- Boiler that will generate steam and power using highly polluting distillery waste – spent wash – as fuel. Distilleries can be highly polluting as 88% of their raw materials result in waste, which is discharged into fields and water bodies. Spent wash is one of the polluting byproducts of the distilling process in molasses-based plants. By generating steam from the spent wash, molasses-based distilleries can significantly reduce their energy costs. Thermax has pioneered the development of such boilers to combat the highly polluting nature of vinasse and has successfully installed them at various locations in India and abroad.

Waste Heat Recovery Power Plants – WHR power plants use waste heat from various sources like cement kilns, blast furnaces, sponge iron kilns, gas turbines etc. and convert these to power, thereby reducing the consumption of fossil fuels. WHR power plants help the customer in moving towards sustainability by reducing the carbon footprint of their operations. With the fuel being practically free, setting up a WHR power plant also helps in improving profitability. Thermax has been at the forefront of commissioning waste heat recovery power plants for more than a decade. Thermax provides a wide variety of customised, turnkey energy solutions to utilise waste heat from various processes and applications.

Thermax believes that by working together and cooperating we can create a sustainable ecosystem where technology can peacefully co-exist with nature. With its technologies and innovations in the field of energy and environment, Thermax empowers the customer to contribute to the development of a better future. Thermax’s solutions ensure better resource productivity, efficient use of energy, as well as cost savings and subsequently, help our planet in the long run.

Act on Climate: A clarion call

Posted on by Thermaxqaz

Act on Climate: A clarion call

Climate change is the biggest threat the world is facing today. From developed countries to developing ones, climate change is a menace all across. According to the United Nations, the climate change that we are witnessing today is caused by several factors such as generating energy, manufacturing goods, deforestation, vehicular emission, waste generation etc.

The effects of climate change are equally varied including hotter temperatures, more cyclonic storms, increased droughts, rising sea levels, loss of biodiversity, food scarcity, more health risks, poverty and displacement etc.     

COP26  

Given the alarming level of climate change and the far worse consequences it entails, the world leaders and governments across the world met at COP26 in Glasgow, Scotland, in November 2021 and pledged to act on climate change mitigation. The COP26 called for the adoption of the Glasgow Climate Pact – a commitment to reach global net-zero emissions target by 2050. The climate pact sought to keep global temperature rise at a 1.5ºC level.

However, the reality is that at the current level we are headed for 2.4ºC warming.

On 28th February 2022, the Intergovernmental Panel on Climate Change (IPCC) released its latest report, which suggested that the climate breakdown is taking place faster than anticipated, thereby closing the window of taking action fast. The report was approved on 4th April 2022, by 195 member governments of the IPCC in March 2022.

‘Red Code for Humanity’

The report suggests that the world must cut its total emissions by 45% by 2030 to avoid climate catastrophe. At current levels, global emissions will increase by almost 14% over this period. If this is the case, the plant will face irreversible impacts such as melting ice caps, frequent and intense weather events, and immense biodiversity and ecosystem loss. The latest report on climate change from the United Nations noted that at least 3.3 billion people’s daily lives are “highly vulnerable” to climate change, and people are 15 times more likely to die from extreme weather than in years past, the Intergovernmental Panel on Climate Change (IPCC) report said.

Rightly the UN secretary-general, António Guterres termed the report the ‘red code for humanity.’

The Swiss Re Institute also finds that the world stands to lose 10% of total economic value from climate change by 2050 if net-zero targets aren’t met. Asia, which has been the cynosure of economic growth in recent decades, stands to lose 26.5% of GDP by 2050, while Africa and the Middle East could lose up to 27.6%.

It’s time we started our act on climate change to stop irreversible damage otherwise an already fragile planet and the socioeconomic system will become even more unstable if enough isn’t done to curb climate change.

Thermax’s role in combatting climate change

Thermax Ltd. is a leading global company providing sustainable solutions for energy and the environment. Thermax group has been pioneering products and solutions that help companies achieve better resource productivity and improve their bottom line while maintaining a cleaner environment.

‘Act On Climate’ is a clarion call encouraging individual action on climate change and sustainability. Thermax, through its gamut of sustainable solutions in clean air, clean energy and clean water, and continuous investment in R&D, is well-positioned to contribute to climate change mitigation.

Sustainable Energy is the Future!

Posted on by Thermaxqaz

Sustaining the Environment

Climate change has reached an alarming level where it is pushing industries and governments across the world to take immediate corrective measures. One of the key factors contributing towards rapid climate change is the reckless use of hydrocarbon fuels for energy generation. This poses major threat to the environment with its unbridled emission and carbon footprint. The solution to stop the rapid degradation of climate and environment lies in the use of renewable energy sources for energy generation.

Energy is the keystone on which our modern civilization is based. The energy-hungry world requires huge quantity of energy – most of which is still met by coal and other fossil fuels – to fulfil everyday requirements. Sustainable energy is the process of energy generation that meets the needs of the present generations without compromising those of the future generations. Sustainable energy is all about finding clean and renewable sources of energy – sources of energy that renew themselves in place of conventional energy sources that deplete gradually and are harmful to the environment.  

Advantages of Sustainable Energy

Several forms of energy are sustainable to the environment. In addition to the most commonly considered sources such as wind, solar, and water, bio-energy and geothermal energy are also renewable sources. Bio-energy is the process of creating energy from biological masses such as straw, manure and other agricultural by-products, while solar energy is energy harnessed from the sun.

Sustainable energy is not only naturally replenished, but it causes no harm to the environment, as there are no greenhouse gasses or other pollutants emitted. Sustainable energy solutions are the best for our homes and businesses as they are not only renewable but are also frequently developed closer to the end-user as compared to conventional power generation systems. Many are already making a move towards solar, wind, cleaner fuels and other sources of sustainable energy. Due to multiple government policies and the development of cost-effective technologies, the price of sustainable energy solutions has decreased dramatically in the last decade, making them more affordable than ever.

Thermax believes that sustainable energy is the future. We, at Thermax, have been working extensively to develop innovative solutions for a sustainable energy future.

Waste to Energy

‘Waste to wealth’ is the main principle of sustainable development and generation of sustainable energy. Waste products such as biomass play an important role as substrates to be used in energy generation. Biomass and ‘waste to energy’ generation are some of the most promising technologies to look forward to trying and developing independence from fossil fuels. Some of these are listed below: 

Biomass-powered boilers: Biomass is renewable organic material that comes from plants and other natural wastes. These are available in large quantities and are mostly dumped in landfills, wasting their potential for energy generation. Biomass boilers come with the capability of using biomass as the source of fuel instead of fossil fuels like coal, oil & gas without compromising the quality of the output. These boilers have various benefits, including fuel flexibility, low maintenance, high efficiency and high reliability.  

Waste to Energy: Through waste-to-energy solutions, various types of wastes such as waste/exhaust heat/biomass/bio-waste can be recovered/utilised to produce energy in the form of steam or power. These type of solutions encompass waste-to-energy power plants, municipal waste incineration boilers, waste heat recovery power plants, etc..

Spent wash (vinasse) fired boiler: Spent wash is one of the polluting by-products of the distilling process in molasses-based plants. Distilleries can be highly polluting as 88% of their raw materials result in waste which is discharged into fields and water bodies. By generating steam from the spent wash, molasses-based distilleries can significantly reduce their energy costs.

Spent wash (vinasse) fired boiler is the answer to combat the highly polluting nature of vinasse. This type of boiler generates steam and power using highly polluting distillery waste – spent wash – as fuel.

Waste heat recovery power plants: WHR power plants use waste heat from various sources like cement kilns, blast furnaces, sponge iron kilns, gas turbines etc. and convert these to power, thereby reducing the consumption of fossil fuels. WHR power plants help the customer move towards sustainability by reducing the carbon footprint of their operations. As the fuel for this plant is practically free, setting up a WHR power plant also helps in improving profitability.

Solar Energy Solutions

Solar energy is the most widely available and the most common sustainable energy solution to further the sustainable development goals of individuals as well as industries. The recent advancements in technology coupled with various government incentives have made solar energy an attractive alternative for many.  

Solar rooftop: Solar energy offers an excellent return on investment (RoI) while utilising the rooftop space of your facility. Solar rooftop solutions can generate free electricity for more than 25 years, resulting in huge savings and reducing the carbon footprint.

Solar ground mounted: Thermax has an excellent track record of installing ground-based solar power projects. Ground-mounted solar installations deliver unbeatable ROI during the lifecycle of the project, taking the manufacturing facility towards self-reliance for its power needs.

Battery energy storage system: Thermax provides specially designed battery energy storage systems with Li-ion technology to provide reliable and long backup. It also forms a hybrid system with solar PVs and a solar power grid.

Sustainable energy generation is inevitable to stop climate change and global warming that would result in severe consequences for both humankind and the planet as a whole. Sustainable energy solutions also offer respite to the energy producers, industries and governments in tandem in the face of rising coal and petroleum prices. With its technologies and innovations in the field of sustainable energy, Thermax helps customers navigate their journey towards sustainable energy solutions for a better future.

The Unprecedented Global Crisis

Amid the biggest climate  crisis the planet is witnessing, where temperatures are forecast to rise above the 1.5°C warming threshold by 2040, we can no longer sit and do nothing. Scientists have warned that the predicted rise in global temperature will lead to catastrophic results which will affect the entire planet. Flooding of coastal areas will occur due to increasing sea level – over 70% of the earth’s coastlines are likely to disappear under seawater, meaning beaches will erode and our coasts will be flooded, and land will shrink in size. Meanwhile, extreme heatwaves and drought will become commonplace and fresh water will become more difficult to source. 

All of these above problems have a common cause – global warming. One of the main perpetrators of global warming is excessive levels of carbon dioxide (CO2) in our atmosphere. Billions of tonnes of carbon dioxide released by countries through the use of fossil fuels like coal and oil to power their economic development account for over 84% of all greenhouse gases released globally. The fact that we have removed at least a third of all forests, thus removing the natural capacity to absorb carbon, has accelerated the problem of global warming. Coal-powered thermal power plants still contribute as a major source of power to industries as well as residential areas. Automobile exhausts are choking the air in major cities like Delhi (India), which regularly features on the list of the cities with the worst air quality. Furthermore, the global demand for water is increasing rapidly due to rising population and growing industrialisation, thus making the availability of clean water a pressing concern. 

This underlines the urgent need to move towards cleaner and greener sources of energy and adopt water conservation strategies to save the planet as well as save ourselves. Natural resources are finite and will be exhausted in the future. Thus, it becomes important for us to develop capacities to harness alternate sources.

How Can We Mitigate This Crisis?

Green Energy Solutions

The key to mitigating the effects of damage caused by the use of fossil fuels is renewable energy. Renewable energy resources are sources of clean, inexhaustible and environmentally conservative energy. Above all, they do not release greenhouse gases or pollutants that can cause climate change. Renewable energy sources are growing in popularity due to increased public awareness about climate change issues, and governments around the world have declared zero carbon emission targets that they hope to achieve in the coming future. India, in particular, has introduced a PLI scheme to incentivise manufacturers to develop solar energy capacity and has introduced several infrastructural projects to further the use of electric vehicles, which will mitigate some of the emissions released from automobiles. Such schemes go hand in hand with the active participation of the entire manufacturing industry to develop capacity for renewable energy and reduce dependence on fossil fuels for conserving the environment.

Thermax has a long history of extensive engagement with diverse sectors and tie-ups with technology majors, which has empowered the group to deliver unmatched solutions to its clientele. Its offerings in waste heat recovery, waste to energy, biomass-based solutions, solar, and bio-CNG show commitment to delivering clean energy. Thermax regularly introduces environment-friendly and carbon-neutral solutions which are capable of replacing most fossil fuels with commercial benefits.

Water Recycling: Need of the Hour

Posted on by Thermaxqaz

Water is a major constituent of life on earth. The earliest life forms are believed to have been originated deep in the primordial oceans. Water also forms around 60% of the adult human body and over 90% of the blood in our body. Thus the relation of water to life is indistinguishable.

Access to clean water is a universal right. However, in the post-industrialised world, there has been a constant degradation of naturally occurring water resources. Freshwater resources are succumbing to the expansion of agricultural or residential lands. The underground water table is also not doing so well after over-exploitation for decades without any measures taken for recharging the water table. It would not be an exaggeration to say that we are currently in the midst of a grave water crisis affecting millions of people.

Thus reusing and utilising recycled water has become a necessity in today’s world where water scarcity is a pressing concern. Industrial water recycling, sewage and effluent treatment, as well as Zero Liquid Discharge solutions, enable industrial establishments to save millions of litres of precious water which would otherwise have flown down the drain.

Over the last four decades, Thermax has been continuously developing and innovating products, systems and services for water and wastewater management. Thermax strives to deploy its engineering prowess to help the customers achieve better resource efficiency while simultaneously conserving water for future generations.

Thermax’s Solutions To Recycle And Conserve Water

Thermax has deployed innovative solutions across various industrial, commercial, rural, hospitality and defence establishments to help them reduce freshwater consumption as well as reuse and recycle the wastewater that they generate.

Thermax offers a wide range of options for conserving water ranging from water treatment plants and zero liquid discharge solutions to sewage treatment and desalination plants. Thermax’s experienced team of professionals and their one-stop solutions to help customers reduce, reuse or recycle water gives them a decisive advantage when compared to its peers.

Water Treatment For Industrial Applications

With stringent pollution and specific water quality requirements for industries, it has become a necessity to treat water from various sources for any further use in the industries. Thermax has quite a successful record in developing ingenious water treatment technologies with a number of operational installed water treatment plants for customers across various sectors.

Water treatment for Industrial Applications is a complex and multistep process involving:

  1. Chemical dosing: Chemical dosing is the adding of chemicals into water/fluid or sludge to achieve the required conditioning. This would make the treatment effective by various mechanisms such as charge neutralisation, settling of solids etc.
  2. Clarifiers: Uses settling tanks to separate solid particulate matter from the liquid.
  3. Filters: Removes the finer impurities from water by using a physical barrier.
  4. Softeners: Widely used for reducing the hardness of the water. The process of softening is a useful and reversible ion exchange process in which the hardness forming ions are exchanged with sodium ions present in the resin group.
  5. Demineralisation (DM): Demineralisation is the most proven and reliable technology used in water treatment to remove minerals, using the principles of ion exchange. De-gasification and polishing are used to produce mineral-free water.
  6. Membrane filtration: Reverse Osmosis (RO), Nanofiltration (NF), Ultrafiltration (UF) are new and advanced methods of purifying water and are membrane-based processes used for the separation of dissolved salts from water which makes it unfit for use.

Recycling Wastewater to Reduce Environmental Pollution

After its use in various industrial processes, the used water becomes unfit for any use due to the addition of many harmful substances to water like heavy metals, which turn water into ‘wastewater’. If the water is released as is into the environment, it will cause major ecological damage and pollute precious natural resources. To prevent such pollution, wastewater is passed through a lengthy treatment process which removes these harmful constituents such as organics, solids, heavy metals etc.

Wastewater treatment plants are designed using a combination of physical, chemical and biological processes so that the treated water can be discharged in the environment or reused further.

Thermax offers decentralised sewage treatment solutions as well as customised treatment plants for industries, housing societies and even commercial complexes. These systems can significantly reduce operational costs as well as reduce the plant’s footprint by more than 60%. The different steps of water treatment are:

  1. Biological treatment – Wastewater is first stabilised biologically by microorganisms that convert colloidal and dissolved organic matter into simpler molecules that can be removed further by gravity settling.
  2. Anaerobic treatment – Anaerobic treatment is an energy-efficient process in which bacteria transforms organic waste in the wastewater into biogas in the absence of oxygen. To achieve this oxygen-free environment, the entry of air into anaerobic tanks is prevented, typically by a gastight cover.
  3. Aerobic treatment – Microbes are used to convert organic wastes into carbon dioxide and other biomass in the presence of oxygen. Aerobic treatment requires a continuous oxygen supply, so forced air from air blowers is mixed with the wastewater, where the aerobic bacteria feed on the waste in the water.
  4. Activated Sludge Process (ASP) – In this process, the microorganisms are first thoroughly mixed with the organic compounds in the wastewater, and their growth is stimulated. As the microorganisms grow and are mixed by the agitation of the air, the individual organisms flocculate to form an active mass of microbes called activated sludge.

Thermax offers a wide range of reactors and similar solutions to recycle the wastewater generated by its customers from various sectors.

  • Up-flow Anaerobic Sludge Blanket (UASB) reactor – It is a type of anaerobic digester that is used for wastewater treatment. In this process, wastewater flows upward through the blanket of sludge, and microorganisms degrade the organic matter and produce methane gas as a by-product, which further can be used as fuel.
  • Sequential Batch Reactor (SBR) – SBR is based on the principle of activated sludge treatment process, an application of ASP that is operated on a batch basis. It is used in small communities where the space for wastewater treatment is limited.
  • Moving Bed Biofilm Reactor (MBBR) – MBBR is a more economical and efficient solution for wastewater treatment. MBBR system consists of an aeration tank containing special plastic elements called media. The bacteria grow on the surface of the media and break down the organic matter from the wastewater.
  • Membrane Bioreactor (MBR) – MBR is used in biological treatment along with membrane separation. A membrane bioreactor consists of a biological reactor containing the suspended biomass and solids separated by Microfiltration (MF) or Ultrafiltration (UF) membranes.

 

Zero Liquid Discharge (ZLD)

As the name indicates ‘Zero Liquid Discharge’ is a special wastewater recycling process designed especially to recycle and limit all liquid wastage to a ‘net zero’. Zero Liquid Discharge (ZLD) plants are seen as the future for developing efficient and sustainable industrial plants. Implementation of the ZLD system requires a hefty investment and increases the cost of production, but the current situation of water scarcity and stricter norms for conserving the environment has forced many industries with a major dependence on water to adopt ZLD systems. Recycling and reuse of treated effluents is worthwhile in the constantly deteriorating environment where water scarcity is a pressing concern. ZLD makes this possible for industries that are keen on resource optimisation.

Thermax provides zero liquid discharge solutions for various industrial wastewaters. The conventional method to achieve ZLD includes thermal technologies such as evaporators like Multi Effect Evaporation (MEE), Mechanical Vapour Compression (MVC) and Agitated Thin Film Dryer (ATFD).

Desalination

With the growing scarcity of water, the treatment of saline seawater is becoming a viable option to get water to run the entire manufacturing process smoothly. Thermax has designed various seawater reverse osmosis systems for an efficient desalination process. These include several successful installations that incorporate energy recovery systems with the desalination process to improve the returns from the system.

Desalination involves removing dissolved minerals from seawater and brackish water (a mixture of fresh water and ocean water) and is an increasingly important source of fresh water. Desalination operates at high pressure as the membrane separation requires a driving force which is provided by a high-pressure pump.

Through desalination, water for human consumption can also be produced. Feedwater may include brackish water, seawater, wells, surface (rivers and streams), wastewater, and process waters. With the rising cost of freshwater and its growing scarcity, the economical treatment of seawater treatment offers the possibility of bridging the demand-supply gap.
