Assessment of Nanofibers Filtration for Textile Waste-water Treatment

El Messiry M, Aloufy A and Elmor M

The finished fabrics need to be bleached, dyed, and printed and these processes require at least 100 liters of water for each ton of fabric. The recycle of industrial wastewater is one of the solutions for efficient use of water resources. In this work, designed filter unit was suggested to be used for the filtration of the wastewater from textile dyeing and finishing mill. Three designs were manufactured using yarns and yarns covered with nanofibers layers were introduced. The results of testing different designs indicate the improvement in the filtration efficiency. Moreover, a case study in the dyeing and finishing textile mill designated that the treatment of the wastewater by the designed filters advanced the filtration efficiency. Unit performance of wastewater treatment was: COD decreased to 52 mg/L, TSS decreased to 300 mg/L, and Turbidity to 70 NTU. The designed filtration unit is suitable to be used, in particular in textile dyeing and finishing SME with small discharge, and can produce treated effluent satisfying the standards regulating wastewater
