Alternative Method for Treatment of Wastewater in Textile industry : Review

In the early days of industrial revolution the waste water generated was simply passed to water bodies like rivers, wells, etc. which was fine for that time as the amount of wastewater generated was very less. The process of dilution was the principle and water purification used to take place by surrounding environment of water called as self-purification of streams. But as soon as the more and more industries were established it was seen that the self-purification process fails to purify water because the quantity of wastewater flown in water bodies was much more than its capacity to purify it. Hence there was a need of effluent treatment plants. Textile industry creates a lot of wastewater having very high amount of color. The color present in water reduces its acceptability aesthetically. Also the color present in water hampers the process of photosynthesis for the plants and other photosynthetic species if directly discharged in water bodies. The textile wastewater also has very high pH, COD, BOD
