      Zero Liquid Discharge (ZLD) Treatment Solutions

Ideal for treating high-strength wastewater and to convert to biogas, energy, and CBG.  


Overview


Zero Liquid Discharge (ZLD) systems are engineered to eliminate all liquid wastewater discharge by recovering water and converting residual waste into solids. Renewsys designs ZLD solutions specifically for high-TDS and complex industrial effluents, where regulatory compliance and water scarcity necessitate complete reuse.   

Unlike conventional ZLD designs, Renewsys applies hybrid treatment approaches, including RO, evaporation, crystallization, and freezing technologies, to minimize energy consumption and lifecycle cost. Each ZLD system is customized based on wastewater composition, recovery targets, and energy optimization to ensure long-term operational viability.
