Textile dyeing industries need huge quantity of water for textiledyeing, which they normally pump out repeatedly from the ground/natural resources, resulting in depletion ofground water level.

In the dyeing process the textile industries generate huge quantity of toxiceffluent water containing colour and sodium sulphate, sodium chloride, sodiumhydroxide and traces of other salts. These are generated after dyeing andafter washing of garments/fabrics. After dyeing the waste water produced iscalled Dye Bath water and after washing the waste water generated is calledwash water.
