Abstract:
The chemical treatability of wastewaters generated from a textile manufacturing plant performing wool, polyester, wool-polyester blends, woven fabric as well as yarn dyeing and finishing operations was investigated. Coagulation and flocculation experiments were conducted with alum, sodium bentonite and iron salts on wastewaters collected from both the fabric finishing line, after being subjected to in-plant control measures covering water conservation practices and segregation of reusable streams, and dyeing line. The effect of optimum treatment alternatives on the chemical oxygen demand (COD) values of different molecular weight cut-off fractions was also examined.
