Zero Liquid Discharge (ZLD) Treatment Solutions
Complete Water Recovery with Zero Wastewater Discharge
Engineered for
Water Scarcity & Regulatory Compliance
Zero Liquid Discharge (ZLD) systems are designed to eliminate all liquid wastewater discharge by recovering reusable water and converting residual contaminants into solid form. Renewsys engineers ZLD solutions specifically for high-TDS and complex industrial effluents, where stringent regulations and water scarcity demand complete reuse.
Rather than relying on energy-intensive conventional designs, Renewsys applies hybrid ZLD configurations—combining reverse osmosis (RO), evaporation, crystallization, and selective freezing technologies. Each system is customized based on wastewater composition, recovery targets, and energy optimization to deliver maximum recovery with minimized operating and lifecycle costs.
