Textile Waste Water and the advanced Oxidative Treatment Process, an Overview

FagbenroOluwakemi Kehinde, Hamidi Abdul Aziz

Sustainability of the environment has become a focus; hence the need for improvement and monitoring of textile waste water discharges, for which major concern is color. Color in textile dyeing and finishing effluents is as a result of large amounts of dye stuffs left during the dyeing stages and inefficient dyeing processes often resulting in unfixed forms. Waste water from Textile and dyeing industries contain many pollutants, making it high in organic and inorganic chemical content, total organic carbon (TOC), chemical oxygen demand (COD), and especially, strong color. It is thus difficult to be degraded by the conventional methods; hence the use of the advanced oxidation processes (AOPs). The advanced oxidative process is certainly not a very new treatment method as it has been studied and used extensively; however, hope remains for possible improvement, hence this review. AOPs are being researched more with a view to improve on the treatability of effluents and the hope to use the method for the complete mineralization of dyes. Although they are very effective in complete mineralization of pollutants, AOPs may be very expensive when used solely.
