Zero Liquid Discharge Systems for Textile Mills
topic
Zero liquid discharge systems for textile mills concentrate and crystallise all dissolved solids from treated effluent through multi-effect evaporation, mechanical vapour recompression, and crystallisation equipment that recovers distilled water for process reuse and dry solid salt for disposal or recovery, eliminating all liquid effluent discharge at the cost of high capital investment and energy consumption for the evaporation stages.
Role
Addresses the regulatory requirements in water-scarce regions and environmentally sensitive discharge zones that mandate zero liquid discharge from textile wet processing by providing the complete effluent elimination technology that recovers all water for reuse and concentrates all dissolved solids into manageable dry waste, with the high energy cost of evaporation being the primary challenge limiting ZLD adoption to regions with severe discharge restrictions that justify the operating cost premium.
