Zero Liquid Discharge System (ZLD)

Zero Liquid Discharge (ZLD) 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. Interest in Zero Liquid Discharge 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 green initiative, public perception of industrial impact on the environment, or concern over the quality and quantity of the water supply. The KEP is providing the turnkey solution for zero liquid discharge, which includes the process like primary treatment, secondary treatment, tertiary treatment and evaporator and dryers. Based on the effluent characteristic’s KEP will select the process of treatment to recycle 100% water to process.
