STRATEGIES FOR EFFLUENT REDUCTION AT SOURCE AND ON-FLOOR MANAGEMENT FOR REUSE, IN CABINET DYEING UNITS FOR YARN DYEINGS. SELVAN AND V. NEHRU KUMAR
The requirement of water in a typical cabinet dyeing system for yarn dyeing is assessed at 140.00 to 165.00 L/kg. The segregation of waste stream into lean wash, spent wash and spent dyebath is found to reduce the effluent from 165 to 105 L/kg and will help the industry to reclaim water from the lean wash effluent by using on-floor management systems having Media and Cartridge Filters. This practice, if incorporated for yarn dying operations, will reduce the required water from 165 L/kg to 105 L/kg in cabinet systems and will reduce the hydraulic loading on the Effluent Treatment Plants.
