Wastewater from dye houses can have strong impacts on the aquatic environment. Due to its complex chemical structure, dye is one of the most difficult constituent in the textile wastewater to treat. The treatment of dye house wastewater constitutes a major economical and environmental issues. Therefore, dye removal from textile wastewater has been receiving a great deal of attention in the last few years. The present review paper describes different methods for the treatment of dye containing wastewater. Starting with the degradation of color by oxidation reaction, their mechanism and advantages are stated. This is followed by an account of degradation of color by anaerobic (reduction) reaction, adsorption of dye by activated carbon, silica, functional polymer granules, and biomaterials are included. Finally, the treatment of dye containing wastewater by nanofiltration is summarized in this review paper.
