Description:
The large quantity of aqueous waste generated by the textile industry is a significant environmental problem. Dye effluents contain chemicals that are toxic to fish and mammalian species. There is currently no single economically feasible method of treating textile effluents. Conventional biological processes have not proven to be particularly effective. Similarly, for disperse dyes, carbon adsorption and ozonation result in poor color removal. Chemical coagulation and reverse osmosis result in a large proportion of color removal, but the former produces large amounts of toxic sludge while the latter involves high capital costs. The novel concept in this Phase I project deals with treating textile wastewaters by an electrochemical approach where oxidation of organic waste is achieved together with the recovery of toxic metals (chromium and copper) found in textile dyes. High molecular weight dyes are decomposed into low molecular weight compounds, which are amenable to biodegradation. Preliminary results have clearly demonstrated the feasibility and the high potential of the new technology to efficiently decompose textile dyes and recover toxic metals resulting from dye decomposition. The objective of this SBIR project is to identify the key features and optimize specific process parameters to achieve maximum process efficiency.Supplemental Keywords:
