ABSTRACT:
A process for removing both color and odor from wastewater effluent that is contaminated from dye complexes, such as azo dye complexes, used for dyeing textiles to be various colors. The process requires treatment of the effluent with alkali metal permanganate, followed by treatment with hydrogen peroxide, followed by treatment a primary coagulant as a flocculation initiator (together with pH control so that the pH is basic), followed by treatment with a water soluble polymer, and followed by separating precipitated flocculated material from the effluent to obtain a clear effluent free of color and odor.
