Özet
Textile wastewater is characterized by strong color, saturation of unfixed dyes and their residues, and organic and inorganic chemicals, such as bleaches, detergents, optical brighteners, fixing, sequestering and finishing agents, carriers, surfactants, equalizers, It is characterized by consumption of high amount of water and production of large volumes of wastewater from various processes, such as dyeing, printing, finishing, The wastewater treatment methods are broadly categorized as physical, chemical and biological. The integrated processes including some combinations of three treatment classes are mostly employed to remove color from dye contaminated effluents and comply with severe regulations. This review revealed that a combination of biosorption followed by ozonation might more efficient in terms of time, cost and toxicity reduction than separately using these processes. To compensate the negative points of both the processes, combined treatment of biosorption followed by subsequent ozonation have been implied. The treatment of ozonation has been increasing for the decolorization of textile dyes, the main disadvantage of this way of apply being related to the by products, which can have toxic and carcinogenic actions. The other disadvantage related to ozonation is its cost and time taken by ozonation. On the other hand, biosorption is a cheap process for the treatment of textile dyes, but it is less efficient in removing dyes as compared to ozonation at higher dye concentrations. It can be suggested that a combination of biosorption followed by ozonation might more efficient and effective for the decolorization of textile dye and to reduce the toxicity of ozonation process. © 2020, Green Wave Publishing of Canada.
