Zero Liquid Discharge (ZLD)

ZERO Liquid Discharge

Zero liquid discharge (ZLD) is an engineering approach to wastewater treatment where all treated clean water is made available for reuse in ongoing industrial operations by removing the impurities & dissolved solids while the contaminants therein are reduced to solid waste. In the case where RO membrane filtration is to be applied, a smaller volume (the reject) will require evaporation i.e. steam evaporator in general and Multieffect evaporator (MEE) in particular is one of main partner and popular method in completing the loop of wastewater treatment to achieve the ZLD. At GEPL, we adopt a project based approach with superior and cost effective engineering design capabilities and manufacturing excellence to deliver a total solution towards achieving ZLD.

We provide turnkey solution for ZLD with primary treatment, secondary treatment, tertiary treatment, evaporation system and ATFD based on the type and characteristics of the effluent We design and manufacture the single and multiple effect evaporators with falling film evaporation and forced circulation crystallizer keeping in mind both sustainability and economy in operation
