What is Zero Liquid Discharge Plant?

Zero Liquid Discharge (ZLD) is an advanced wastewater treatment process in which all liquid waste is treated, purified, and reused, leaving only solid residue for disposal.

A ZLD plant uses multiple processes such as:

Pre-treatment
Reverse osmosis
Multiple effect evaporation (MEE)
Crystallization
Sludge drying

This creates a closed-loop system where water is recovered and reused, ensuring no liquid discharge into the environment.

ZLD systems are required for industries facing strict CPCB / SPCB / Pollution Control Board norms and water scarcity issues.
