Zero Liquid Discharge for industry
Recover your water. End your discharge liability.
Zero Liquid Discharge (ZLD) means no wastewater leaves your site as a liquid. We supply, install and operate the equipment, and you pay a fixed rate per m³ treated, with no upfront investment.
Why ZLD projects stall
Zero liquid discharge works. Cost and complexity stop most projects.
Four barriers come up again and again. Here is how we solve each one.
Evaporating all the effluent costs 30–60 kWh/m³.
Our answerThe membrane removes up to 95% of the water before any heat is applied. The complete train needs under 10 kWh/m³.
Multi-million CapEx and years of payback before the first m³.
Our answerA rate per m³ treated. We supply, install and operate, and the investment is ours.
Scaling and corrosion stop plants and drive up maintenance.
Our answerA batch circuit that flushes itself every cycle, plastic and titanium materials, and no exposed hot steel.
Evaporation ponds take hectares and depend on sun and rain.
Our answerCEE modules of 9 m² running at ambient temperature, scaled without civil works.

How it works
Wastewater in. Water recovered, the rest concentrated.
Batch RO recovers the water. The concentrate it leaves feeds straight into the CEE evaporator, which concentrates it further so only a small final residue needs disposal. Each stage is also sold on its own.
- Input
Conditioned effluent
Filtration and adjustment beforehand.
- Stage 1
Batch RO
Recovers the bulk of the water at minimum energy. Partner: Salinity Solutions.
→ reusable water - Stage 2
CEE Gen9
Concentrates what Batch RO leaves behind, in a module instead of a pond. Partner: Quadsun.
→ further concentration - Output
Final residue
The only part that leaves for disposal. No liquid discharge.
Zero liquid discharge
Removing water with a membrane costs a few kWh/m³. Removing it with heat costs tens. So the membrane works up to its ceiling and evaporation only finishes what is left. Together the two stages form RealZLD, our integrated system.
The model
You pay per m³ treated. Nothing more.
We supply, install, operate and maintain. Energy, reagents and membrane life are our risk, not your budget.
- Variable cost, aligned with real volume.
- No asset to amortise and no investment to approve.
- Recovery and output quality guaranteed by contract.
- Less external waste management.
