Waste water treatment process using Nano TiO2

Textile industry outlet Waste water contain a several mixture of polluting substances involving solvents, detergents and dyes. Textile manufacturers are in a situation to sort out this issue by adopting a suitable treatment technology for textile effluent. Notably the application of ceramic Nano Filtration (NF) plays a significant role in recycling the specific waste in the textile industry thereby paving way to waste recycling instead of being disposed of in land whereas it seems to be impossible for most of the conventional technologies in treating this textile effluents. The Initial performances of commercial NF membranes have been studied thoroughly pertaining to Total Dissolved Solids (TDS), Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) rejection. The outcome showed that maximum separation of dye and salts where achieved by some of the commercial membranes while some achieved higher flux owing to the inconsistent parameters of textile waste water and NF membranes chosen. These work forefronts and studied the problem associated with textile waste water and waste water recycling using the ceramic nano filtration membrane. (C) 2019 Elsevier Ltd. All rights reserved.
