Abstract

The Zero Liquid Discharge (ZLD) process involves several stages, including pretreatment, evaporation, crystallization, and solid waste management. Pretreatment removes solids, oils, and contaminants from the wastewater. Evaporation applies heat to evaporate water, leaving behind concentrated brine or salts. Crystallization or membrane filtration further separates dissolved salts and minerals, ensuring the treated water meets required quality standards. Solid waste generated during the process is appropriately managed or repurposed.
