Zero liquid discharge (ZLD) systems recover almost all water from industrial effluent and convert the remaining salts into solids, so no liquid effluent is discharged. ZLD is increasingly required by pollution control boards for textile, pharmaceutical, chemical and other industries. WEEN Techsol engineers complete ZLD systems from pre-treatment to evaporation.
A reliable ZLD plant depends on getting each stage right and balancing them together.
Preparing effluent for membranes and evaporators.
Recovering most of the water at low energy.
Turning concentrated reject into solids.
From your ETP
Remove hardness & solids
Recover water
Concentrate reject
Salts for disposal
We focus on the mass balance and pre-treatment that make or break ZLD plants in operation.
