Abstract

Release of colored wastewaters represents a major environmental problem worldwide due to the toxicity, mutagenicity and carcinogenicity of the dyes and their breakdown products. Therefore much attention has been focused on the effective treatment of dyes discharged from the dying and textile industries. The most widely used dyes in industries are azo dyes which require anaerobic and aerobic phases for their complete biodegradation. Color is removed under anaerobic conditions in which azo dyes act an electron acceptor. Further, aerobic conditions are essential for removal of breakdown products which are known resist to biodegradation under anaerobic conditions. Thus using both anaerobic and aerobic stages represents both decolorization and mineralization of azo dyes. Anaerobic stage is the first and the most important phase for color removal, however; decolorization can be affected by so many parameters such as; organic carbon source added, microorganisms selected, dye structure, cycle time, sludge age, and alternative electron acceptors involved. This review article summarizes the results of several research studies dealing with the factors affecting anaerobic color removal efficiency.
