Zero Liquid Discharge Systems

Zero Liquid Discharge describes a process that completely eliminates liquid discharge from a system. The goal of any well-designed ZLD system is to minimize the volume of wastewater that requires treatment, process wastewater in an economically feasible manner, while also producing a clean stream suitable for reuse elsewhere in the facility.
These ZLD systems employ the most advanced wastewater treatment technologies to purify and recycle virtually all of the wastewater produced from reverse osmosis (RO) or ion exchange, cooling tower blow down, spent coolants, DI regenerant, metal finishing wastewaters, tank or equipment washing wastewaters, and other miscellaneous industrial wastewaters such as compressor condensate and floor scrubber wash waters. The equipment needed to achieve ZLD varies depending on the characteristics of the wastewater as well as the wastewater volume.
