Solution 03
Zero liquid discharge (ZLD)
ZLD schemes for plants operating under zero-discharge consent conditions. We build the water balance first, maximise membrane recovery before thermal load, and size evaporation only for the residual — because every m³ pushed into an evaporator is an energy bill for the plant's lifetime.
- MEE
- Crystalliser
- ATFD
- RO

Process and technologies
High-recovery RO
Multi-stage RO with EXO-DESCALER conditioning to hold recovery high without scaling the tail elements.
MEE
Multiple-effect evaporation with thermal or mechanical vapour recompression to cut steam consumption per m³.
Crystalliser
Salt recovery from the concentrated stream, producing a handleable solid instead of a stored brine liability.
ATFD
Agitated thin-film drying of the final slurry to a dry, disposable or saleable solid.
Typical performance
Inlet against outlet
Representative ranges from delivered plants. Guaranteed values are fixed against your own inlet analysis and consent conditions at proposal stage.

| Parameter | Inlet | Outlet |
|---|---|---|
| Water recovery | — | Up to 95% overall (85–90% via membranes) |
| TDS | 15,000–40,000 mg/L | Recovered permeate < 100 mg/L |
| Liquid discharge | — | Nil |
Reference
ZLD for a textile processing unit
Membrane-led recovery ahead of thermal stages to cut evaporator duty and operating cost. 40 KLD scheme at Ambernath with 90% membrane recovery ahead of the evaporator, nil liquid discharge under MPCB consent, commissioned 2024.
