In recent years, the issue of industrial wastewater management has become an increasingly pressing concern for businesses across a wide range of industries. Traditional wastewater treatment methods can be expensive, time-consuming, and often result in the release of pollutants into the environment. As a result, many businesses are turning to innovative solutions like zero liquid discharge systems in India to address these challenges.
What is Zero Liquid Discharge?
Zero liquid discharge in India is a wastewater treatment process that aims to eliminate the discharge of any liquid effluent into the environment. Instead of releasing wastewater into nearby bodies of water or sewer systems, this system collects and treats the wastewater on-site, resulting in the production of dry solids and clean water that can be reused or recycled.
Zero liquid discharge system work by using a combination of physical, chemical, and biological treatment methods to remove contaminants from the wastewater. The treated wastewater is then evaporated, leaving behind dry solids that can be disposed of or used as a valuable byproduct. The remaining clean water can be reused within the facility for purposes like cooling, cleaning, or irrigation.
Benefits of Zero Liquid Discharge System
There are numerous benefits to implementing a zero liquid discharge system within an industrial facility. Some of the most significant benefits include:
Conserves water resources by recycling wastewater: Zero Liquid Discharge System recycles and reuses wastewater, which reduces the amount of freshwater needed for industrial processes. This helps conserve water resources and promotes sustainable water management practices.

ZLD by SCALEBAN Equipments Pvt. Ltd. is the world’s only company providing a unique, disruptive, and sustainable technology for Water Treatment Plant and Zero Liquid Discharge (ZLD) objectives globally i.e. without wastewater RO and Evaporator (MEE) which consume a high amount of power and steam to operate resulting in high CO2 emission which is again a global concern, with Scaleban technology, industries can utilize ETP treated water as makeup to cooling tower and can achieve 15-20 COC against conventional ways where cooling towers maintain 5-6 COC max. despite using Soft and RO water in cooling towers. Higher COC leads to negligible blowdown hence reducing the load on ETP too.
Applications of Zero Liquid Discharge System
Zero liquid discharge system can be used in a wide range of industrial applications, including:
Oil & Gas Plants: The oil and gas industry generates large volumes of wastewater during the production, refining, and processing of crude oil and natural gas. This wastewater contains high levels of contaminants, including heavy metals, organic compounds, and salts. By implementing the ZLD system, these contaminants can be removed from the wastewater and the water can be reused or safely discharged into the environment. ZLD not only reduces the industry’s environmental footprint but also helps to conserve precious freshwater resources.
Chemical Plants: Chemical manufacturing plants produce a wide range of chemicals, including acids, alkalis, solvents, and other hazardous substances. These plants generate large volumes of wastewater that contain high levels of pollutants, including heavy metals, solvents, and acids. ZLD is often used in chemical manufacturing to treat this wastewater and remove these pollutants, ensuring that they do not harm the environment or public health. ZLD also helps chemical manufacturers comply with environmental regulations and reduce their operating costs by recovering valuable resources from wastewater.
Power plants: Power plants generate electricity by burning fossil fuels such as coal, oil, and natural gas. This process produces large volumes of wastewater that contain high levels of dissolved solids, metals, and other pollutants. ZLD can be used to treat this wastewater and remove these pollutants, ensuring that they do not contaminate nearby waterways or harm local ecosystems. In addition, ZLD can help power plants reduce their water usage and improve their overall environmental performance.
Pharmaceutical Plants: Pharmaceutical manufacturing plants produce a wide range of drugs and other products. These plants generate large volumes of wastewater that contain high levels of pharmaceuticals and other organic compounds. ZLD can be used to treat this wastewater and remove these compounds, ensuring that they do not enter the environment and pose a risk to public health. ZLD also helps pharmaceutical manufacturers comply with environmental regulations and reduce their operating costs by recovering valuable resources from wastewater.
Petrochemicals Plants: Petrochemical plants produce a variety of chemicals and products from petroleum, including plastics, solvents, and other chemicals. These plants generate large volumes of wastewater that contain high levels of pollutants, including heavy metals and organic compounds. ZLD can be used to treat this wastewater and remove these pollutants, ensuring that they do not harm the environment or public health. By implementing ZLD, petrochemical manufacturers can also reduce their water usage and improve their overall environmental performance.
Textile Plants: Textile manufacturing plants produce clothing, fabrics, and other textile products. These plants generate large volumes of wastewater that contain high levels of dyes, solvents, and other pollutants.
