Zero Liquid Discharge

Membrane concentration and thermal evaporation systems that eliminate liquid effluent discharge.

Overview

Zero Liquid Discharge

Zero Liquid Discharge (ZLD) systems recover water from high-TDS or RO-reject streams so industries can eliminate liquid effluent discharge — combining membrane concentration with thermal evaporation and crystallization.

Technologies

Treatment Technologies

MEE

Multi-Effect Evaporator — thermal concentration of high-TDS reject streams.

MVR

Mechanical Vapor Recompression — energy-efficient evaporation for brine concentration.

ATFD

Agitated Thin Film Dryer — converts concentrated brine to solid residue for final disposal.

Crystallizers

Recover dissolved salts as solid crystals from concentrated brine.

Plant Types
