  • WASTE WATER AND ITS TREATMENT IN TEXTILE INDUSTRY

    1. 1. WASTE WATER ANDITS TREATMENT INTEXTILE INDUSTRYVANDANA TRIPATHI
    2. 2. • Textile wastewater includes a large variety of dyes andchemical additions that make the environmental challengefor textile industry not only as liquid waste but also in itschemical composition.•Main pollution in textile wastewater come from dyeingand finishing processes.•These processes require the input of a wide range ofchemicals and dyestuffs, which generally are organiccompounds of complex structure.•Water is used as the principal medium to apply dyes andvarious chemicals for finishes.•Because all of them are not contained in the final product,became waste and caused disposal problems.•Major pollutants in textile wastewaters are high suspendedsolids, chemical oxygen demand, heat, colour, acidity, andother soluble substances.•Substances which need to be removed from textilewastewater are mainly COD, BOD, nitrogen, heavy metalsand dyestuffs1,2.
