Zero Liquid Discharge (ZLD) System

Concentrator plus crystalliser trains that take industrial effluent to dry solids — for sites with no discharge permit at all.

  • ZC-ZLD-100
  • 50–500 m³/day
Zero Liquid Discharge (ZLD) System

What makes this system different

  • Liquid discharge reduced to zero
  • Staged build to spread CAPEX
  • Salt recovery and resale option
  • Full compliance documentation

When the discharge permit is zero, the water has to leave as vapour and the salts as solids. We build the train in stages so the capital can follow the compliance deadline.

  • Softening and preconcentration by RO / NF
  • DTRO or MVC concentrator
  • Forced-circulation crystalliser
  • Solid handling and packaging
