India is largest producers of textile goods like Synthetic yarn, Cotton Yarn, Clothes, Hosiery etc. It covers major demands of textile goods of world requirement. During manufacturing of textile goods there are large amount of wastewater generated. This polluted water containing hazardous chemicals. This effluent should be treated as per direction given by pollution board authority so that disposal will not be a problem for industries.


In general textile processing units has setup effluent treatment plants either individually or wherever possible central effluent treatment plants. Existing effluent treatment covers Primary, Secondary and in some case Tertiary treatment by normal method. Even though the above treatment scheme is not able to control parameters as per pollution board limit. Still some effective technology is required to control all parameters and if possible recycle pure water as much as possible as now it is future demand to save fresh water.

Membrane processes have many cost effective applications in the textile industry. The cost competitiveness results from: The ability to recover materials with value, recycle water reducing fresh water consumption and wastewater treatment costs, the use of a point source approach for minimum capital costs, small disposal volumes which minimizes waste disposal costs, reduction of regulatory pressures and fines improved heat recovery systems. The textile industry is advancing toward more a closed operation. Strategically placed membrane systems will play an important role in recovering chemicals which used to go to the sewer, and in providing the high quality water needed to produce top quality goods the first time, every time.

Here membrane technology has answer. It will be incorporated as a tertiary treatment to control all parameters as per pollution board limit and recycle pure water from wastewater.
