Research on the Treatment of Wastewaterin the Textile Industry

Abstract

Taking into account the statistical data gathered in two previously published papers concerning the pollution sources in the production sector, namely Finishing section, various solutions are proposed for wastewater treatment. Bearing in mind the results obtained through the sampling method on different types of water in the urban sanitary sewer system, the conclusion was that the most convenient alternative, besides the source control is the treatment in wastewater treatment plants. This is due to the wastewater recycling systems which no longer ask for the optimization of the dilution treatment, through water supply from other systems. A chart of the reengineered sewage treatment works was also proposed.

Reducing the Environmental Impact of Textile Dyes Containg Wastewater by Photocatalytic Degradation with Zincoxide Nanocoated Fibers

“…In order to evaluate the environmental impact generated by the environmental aspects identified in places where wastewater interfere, all the characteristics of the resulted wastewaters, as well as the correct/appropriate/adequate evaluation criteria of the associated impacts should take into account. The environmental impact of wastewaters could be decreased through a physico-chemical treatment of 80-85% and a biological treatment of 15-20% (Savin, 2009). An alternative to conventional methods of removal of organic pollutants from water is semiconductor photocatalytic oxidation of organic substances.…”

Electrochemical treatment of industry wastewaters by capacitive deionization, electrocoagulation and electrooxidation

“…Conventional biological processes are often less successful because most of dyes are barely or non biodegradable [132,134,135,148,151,154]. Electrochemical processes have been proved viable alternatives or complementary to biological treatment in some instances, especially when pollutants are recalcitrant to biological processing.…”

“…Conventional biological treatment processes are often less successful because these dyes are barely or non biodegradable (Beydill et al, 2001;Cailean et al, 2009a;2009b;Lei et al, 1997;Savin and Butnaru, 2009;. Degradation of copper phthalocyanines by heterogenous or homogenous photocatalytic processes (Caliman et al, 2007) and UV irradiation in the presence of H 2 O 2 have been reported (Dos Santos and Masini, 2009;Shu and Chang, 2005).…”
