Zero Liquid Discharge (ZLD) is an advanced wastewater treatment process that eliminates liquid waste by recovering and recycling all water from industrial effluent. Through filtration, evaporation, and crystallization, ZLD ensures only solid waste is discharged. It supports environmental sustainability, conserves water, and helps industries comply with strict pollution control https://medium.com/@zeroliquiddischargee/zero-liquid-discharge-zld-an-ecological-method-for-managing-wastewater-by-hyperfilteration-0579cbbe96de
