Our approach

Holistic approach, from effluent to product

Every site presents its own complex brine chemistry. We start from the whole system — upstream and downstream — and engineer the route that recovers the most value from every stream.

Recover

Reclaim up to 99% of water on-site and cut freshwater withdrawal — creating a circular water loop for the whole plant.

Valorise

Split mixed brine into individual NaCl and Na₂SO₄ products at 98.5%+ purity — turning waste salt into a valuable commercial resource.

Renew

Return recovered salt and recovered water back to industries — closing the industrial loop for a sustainable future.

The MS³-BriMax platform

Selective separation, not brute-force evaporation

We split mixed-salt brine into clean water and individual, saleable salts — at the RO feed and/or reject stage, before the expensive thermal step. Less energy, less waste, more value.

Why conventional ZLD struggles

The mixed-salt bottleneck

Zero Liquid Discharge is mandated for textiles, tanneries, chemicals, power , Paper, Pharma and electronics — but the conventional route is brutal on opex and energy, and it ends in dead-end waste.

Energy-heavy thermal route

Thermal MVRE / MEE routes cost 2–4× conventional treatment and can burn 50–80 kWh per m³ — a cost center, not an asset.

Hazardous mixed salt

Evaporator mixed salt is CPCB-classified hazardous waste — costly TSDF disposal, perpetual liability and zero value.

Our answer

Separate the salts,Shrink the thermal load, crystallize them, Sale them. Recover the water.

How it works

The MS³-BriMax process, step by step

A membrane-led train that does the separation work upstream, leaving only a small polishing duty for the crystallizer.

RO reject in

~5-6% TDS mixed NaCl + Na₂SO₄ brine with other impurities enters the train.

Pretreatment

Hardness, silica and organics are polished out to protect the selective membranes as required.

MS³ selective separation

The patented MS³ step splits the brine into clean NaCl (8–12%) and Na₂SO₄ (~18%) streams.

BriMax concentration

Non-thermal concentration to a ~18–22% NaCl stream at ~35 °C — no boiling required.

Thermal — polishing only

Final crystallization runs as a light polishing duty, with ~60% lower evaporation load.

Products out

NaCl 98.5%+ and Na₂SO₄ 98.5%+ recovered as saleable salts, plus reusable water.

Process route comparison

Two routes, two outcomes

Same RO reject in. One route sells the salt; the other buries it. Here's the difference on the same feed.

Industries we serve

One platform, seven high-salinity sectors

Wherever ZLD is mandated and brine is complex, selective separation turns a compliance burden into recovered water and saleable salt.

Textiles

Dye-house and CETP high-TDS effluent — recover water and split mixed salt into reusable NaCl and Na₂SO₄ instead of landfilling it.

Tannery

Salt-heavy, chloride-rich streams handled at source — reducing hazardous mixed-salt generation and disposal liability.

Desalination

Lift permeate recovery, cut seawater intake and shrink reject volume — turning brine into recoverable product.

Pulp & Paper

High-volume process water recovered and recycled, lowering freshwater draw and effluent load.

Chlor-Alkali

Recovered membrane-grade NaCl returns as feed — a closed loop back to the industry that produced the effluent.

Pharma

Complex, regulated effluent with strict discharge norms — compliant ZLD with resource recovery built in.

Oil & Gas

Produced water and high-salinity streams concentrated and separated for reuse and safe handling.

New-wave demand

Solar PV, electronics and gigafactory build-outs are creating fresh high-purity water and brine challenges — squarely in our range.

Cluster infrastructure

Common Salt Valorisation Facility (CSVF)

A government-permitted, cluster-level hub that replaces TSDF landfilling — waste salt in, saleable salts out. One facility serves an entire industrial estate.

The same tonne is handled once and put back to productive use — clusters cut disposal cost and long-term liability.

Enablers: SPCB / CPCB authorisation under HWM Rules 2016 · state policy for co-processing & utilisation of waste salt · cluster / ETP partnership.

Cluster industries

Waste salt & RO-reject brine handed over officially, under proper authorisation.

CSVF processing

patented MS³-BriMax selective separation under SPCB-authorised intake.

Pure salts sold

NaCl → chlor-alkali · Na₂SO₄ → glass & detergents, under offtake arrangements.

Minimal residue

Only a small non-recoverable fraction goes to secure landfill — the rest is diverted.

Why it matters

Circular economy, made bankable

Lower carbon

Selective separation cuts thermal duty and haulage — up to 35% lower CO₂ versus brute-force thermal ZLD.

Full compliance

HWM Rules 2016 compliance with an audit trail — clusters cut landfill liability and can support SDG reporting.

Real value recovered

Water and salt return to industry as product — resource recovery instead of perpetual disposal cost.
