14 - Sustainable approaches in effluent treatment: Recent developments in the fashion manufacturing

Abstract

Textile and clothing industry, besides being a growing market worldwide, is also a big contributor to environmental pollution due to the generation of highly polluted wastewater. Textile dyeing and processing utilized large amount of water and in turn generates huge amount of polluted water. Because of the serious concern of environmentalist, the discard of this water to the river stream without treatment is banned. Therefore, the industries have adopted the various strategies to deal with the effluent before its discard to stream. Moreover, because of scarcity of water in near future, the reutilization of treated water can also be a useful approach. In this chapter, various physical, chemical, biological, and hybrid methods are discussed to deal with the effluent water. Physical methods such as filtration, coagulation, chemical methods such as oxidation, and biological methods such as aerobic and anaerobic oxidation are discussed in respect of the development done in past years with their loopholes. A hybrid approach utilizing the collective effort of all these methods is also discussed.
