Zero Liquid Discharge (ZLD) is an advanced industrial wastewater management system that ensures no liquid effluent is released into the environment. It operates through processes like ultrafiltration (UF), reverse osmosis (RO), multiple-effect evaporators (MEE), and crystallizers to recover and recycle maximum water. The remaining waste is converted into solid salts for safe disposal or reuse. ZLD helps industries reduce freshwater consumption, meet environmental regulations, and achieve long-term sustainability goals.
