A high content of pigments and other additives with complex structures has been found in the discharge which is not only toxic to marine life, but also mutagenic for humans, as a major source of water pollution. The removal of the dyes is often more important because of their complex aromatic molecular structures, which are frequently synthesized to resist soap, water, light or oxidizing agents which make them more stable and less naturally degradable. Therefore, the physical and chemical methods do not often remove dyes effectively. Bioremediation of textile waste water using different microorganisms has achieved considerable prominence as a very safe, affordable and adequate solution. The emphasis of this analysis is primarily on the contribution of biological treatments using different microorganisms with their mechanism in this field from textile effluent in addition to various physico-chemical process for textile wastewater treatment. It also focuses on the different factor affecting decolorization of degradation process for different reactive dyes
