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
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.
Zero Liquid Discharge System which includes Stripper Column, Multi Effect Evaporator and Agitated Thin Film Dryer
Distillation Column for solvent recovery
Agitated thin film dryer for drying of product with LOD less than 5%
Evaporator for concentration of product
