ZLD & Resource Recovery

Evaporation, Drying & Recovery Systems

Engineered thermal and recovery technologies for zero liquid discharge — concentrating effluent, drying residues, and recovering water, salts, caustic and solvents for reuse.

Multiple Effect Evaporator (MEE)

Steam-driven multi-stage evaporation to concentrate high-TDS effluent and minimise liquid discharge — the workhorse thermal stage of ZLD.

Mechanical Vapour Recompression (MVR)

Highly energy-efficient evaporation that recycles vapour, cutting steam consumption up to 90% for lower-cost ZLD.

Agitated Thin Film Dryer (ATFD)

Final drying stage for viscous, heat-sensitive and fouling slurries, producing a dry solid for true zero liquid discharge.

Salt Recovery Plant

Recovers reusable salts such as Na₂SO₄ and NaCl from ZLD brine by crystallisation — circular resource use and waste minimisation.

Caustic Recovery Plant (CRP)

Concentrates weak mercerising lye back to strong caustic soda for reuse — cutting chemical cost and effluent load.

Solvent Recovery Systems

Recovers and reuses solvents by distillation — reducing hazardous waste, raw-material cost, and environmental impact.

Skid-Mounted MVR Pilot

A transportable pilot unit for on-site trials — evaluate your wastewater and optimise the process before full-scale investment.
