Zero Liquid Discharge (ZLD) describes a wastewater treatment 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 further treatment, process wastewater in an economically feasible manner, while also producing a clean stream suitable for reuse elsewhere in the facility.

Interest in ZLD water treatment technology has grown in the industrial manufacturing sector over the past decade. Companies may begin to explore ZLD because of ever tightening wastewater disposal regulations, company mandated, public perception of industrial impact on the environment, or concern over the quality and quantity of the water supply.

ZLD is a water treatment process in which all wastewater is purified and recycled; therefore, leaving zero discharge at the end of the treatment cycle. ZLD is an advanced wastewater treatment method that includes ultra filtration, reverse osmosis, evaporation / crystallization, and fractional electrode ionization. INHIBEO has an unparalleled depth of experience in ZLD.
