Zero Liquid Discharge Plant
CPCB defines ZLD as systems that enable complete recycling of industrial effluent, ensuring no liquid waste (effluent) is discharged into water bodies or land. The remaining residues must be concentrated and converted into solid form.
Zero Liquid Discharge is a comprehensive solution enabling industries to recycle more than 90% of their waste water for their process and civil water needs.
Since 2015, CPCB has mandated ZLD for specific high-polluting sectors and in general, for any industry operating in water-stressed regions or critical pollution zones, ZLD is now compulsory—no untreated or treated effluents may be discharged out of the industry premises. ZLD implementation aligns with broad guidelines under ESG, sustainability, NSG and reuse.
At Distington Engineers we custom design ZLD solutions for industries keeping in mind industry specific waste water parameters, current regional requirements mandated by PCB, reusability of treated water, operating and capital cost affordability.

What Is a Zero Liquid Discharge Plant?
The shortage of water and environmental laws have ensured that management of wastewater has become one of the most important issues for industries today. A Zero Liquid Discharge Plant (ZLD Plant) is a new-fangled treatment system aimed at making sure that no liquid waste can be discharged from the plant.
Rather, wastewater is recycled, reused, and treated whilst solid residues are disposed of safely. Distington Engineers and Consultants, being one of the top Zero Liquid Discharge plant manufacturers in Indore, provides sustainable and efficient ZLD products to industrial and commercial use.
An effective ZLD plant will assist industries in being in regulatory compliance, water conservation, and impact mitigation.
How Does a Zero Liquid Discharge Plant Work?
Zero Liquid Discharge plant uses a mix of physical, chemical, biological, and thermal treatment in order to recover as much water as possible, and to get rid of the liquid waste.
It normally starts with pre-treatment, which removes suspended solids, oil, and grease by the use of screens, clarifiers, and filtration units. The water is then treated and fed to membrane systems like RO and ultrafiltration, where clean permeate is collected to be recycled.
The concentrated reject stream is then processed in evaporators and crystallizers, whereby water is extracted as condensate and solid crystallized to be discarded. Recycled water is put back into the process, and dry salts or sludge is safely disposed of. This is an integrated method whereby liquid effluent is not discharged into the plant.
Benefits of Zero Liquid Discharge Plants in Industry
Zero Liquid Discharge Systems have a number of operational and environmental benefits:
- Full reduction of wastewater release.
- Maximum treatment and reuse of treated water.
- Less reliance on water resources.
- Adherence to strict environmental rules.
- Reduced chances of punishment and lawsuits.
- Value recovery of salts and by-products.
- Cost saving and long-term sustainability.
All these advantages render ZLD plants the right investment to water intensive industries.
Why Is Zero Liquid Discharge Important?
The lack of liquid discharge is necessary in areas that have water shortages and high pollution control standards. It ensures rivers, lakes, and groundwater are not polluted, and that industrial development becomes responsible. ZLD systems aid industries in complying with the CPCB and State Pollution Control Board standards to safeguard human health and enhance sustainable water management measures.
ZLD has in other industries like textiles, chemicals, and pharmaceuticals, become a regulatory model and not an option, and thus an advanced treatment system is essential.
Applications of Zero Liquid Discharge Plants
Zero liquid discharge plants find application in:
- Dyeing and textile factories.
- Drugs and chemical production.
- Thermal stations and power plants.
- Distilleries and fermenting plants.
- Pulp and paper industries
- Metal finishing and electroplating departments.
- Industrial parks and special economic areas.
Such uses demand a water recovery that is very efficient and a very rigid regulation of effluent disposal.
