Zero Liquid Discharge

Zero Liquid Discharge (ZLD) is a wastewater treatment process developed to completely eliminate all liquid discharge from a system. The goal of a zero liquid discharge system is to reduce the volume of wastewater that requires further treatment, economically process wastewater and produce a clean stream suitable for reuse. Companies may begin to explore ZLD because of ever-tightening wastewater disposal regulations, company mandated green initiatives, public perception of industrial impact on the environment, or concern over the quality and quantity of the water supply.

  • Meet stringent cooling tower blow down and flue gas desulfurization (FGD) discharge regulations.
  • Treat and recover valuable products from waste streams.
  • Better manage produced water.

A Zero liquid discharge facility (ZLD), is an industrial plant without discharge of wastewaters. Target ZLD is normally reached by evaporator and crystallizer unit.
