ZERO LIQUID DISCHARGE
Zero Liquid Discharge (ZLD)
We provide various equipment for effective treatment of waste water to ZLD norms waste water
Zero Liquid Discharge is a classification of effluent treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable for reuse. ZLD systems employ wastewater treatment technologies and desalination to purify and recycle virtually all wastewater received
Ensuring high TDS, high COD effluent is totally recycled through final use of Agitated Thin Film Dryer (ATFD), Multiple Effect Evaporator (MEE) etc.
The ZLD system uses a variety of modern wastewater treatment technologies to store, collect, and reuse ‘treated’ wastewater, ensuring that no wastewater is discharged into the environment.
Installation of equipment and systems that allow industrial effluent to be entirely cycled via permeate and converted to solid utilizing a concentration and heat evaporation process for the dissolved organic and inorganic compounds and salts.
Pre-treatment: Waste water is filtered using membrane technologies such as ultra-filtration, Reverse osmosis etc. separated water is reused, and a concentrate (polluted stream) is further treated.
Evaporation: The concentrate is next sent through a brine concentrator, which is a mechanical evaporator that uses a mix of heat and vapor compression to produce wet sludge.
- Crystallization: Using high pressure steam, the sludge is converted to solid waste, and any residual water is clean enough to reuse.
Importance Of Zero Liquid Discharge Plant.
Several advantages come with implementing ZLD, such as, corporate accountability, and environmental care. By decreasing off-site trucking, running an internal ZLD plant can save disposal costs, promote water reuse, and reduce greenhouse gas emissions. As a result, the climate and nearby ecosystems are less affected.

Key Steps of Zero Liquid Discharge Process
- Involves a range of advanced water treatment technologies.
-
Pre-treatment: Waste water is filtered using membrane technologies such as ultra-filtration, Reverse osmosis etc. separated water is reused, and a concentrate (polluted stream)
is further treated. -
Evaporation: The concentrate is next sent through a brine concentrator, which is a mechanical evaporator that uses a
mix of heat and vapor compression to produce wet sludge. - Crystallization:Using high pressure steam, the sludge is converted to solid waste, and any residual water is clean enough to reuse.
- A Common ZLD approach is to concentrate the wastewater through well designed multiple membrane systems and then dispose of it as a liquid brine or further crystallize the brine to a solid.
- A typical evaporator uses tube-style heat exchangers. The evaporated water is recovered and recycled while the brine is concentrated to a higher solids Concentration.
- Concentrated brine treatment is done in a crystallizing system, such as Agitated Thin Film Dryer (ATFD) or a spray dryer. Crystallized solids in most of the cases is categorized as hazardous waste and disposed off periodicall

Benefits of Zero Liquid Discharge
Zero liquid discharge plant technology is growing globally as an important wastewater management strategy to reduce water pollution and extend water supply. The main benefits of ZLD are: Minimizes wastewater discharge. Maximizes water recovery
