Several small scale industries have formed cooperatives and established Common Effluent Treatment Plants (CETP) to treat wastewater in India. The wastewaters are subjected to primary treatment in the industry and thereafter discharged to be further treated at the CETPs. The management and treatment costs are shared by the member industries. The CETP under study is situated in North Western part...

In this research, the removal of malachite green dye from Textile Wastewaters using polyaniline coated onto sawdust (PAni/SD) has been investigated. Ammonium peroxodisulphate was used as chemical oxidant for polymerization of polyaniline directly on the surface of sawdust. The effects of some important parameters such as pH, initial concentration, sorbent dosage, exposure time and temperature o...

High amounts of toxic textile dyes are released into the environment due to coloring and wastewaters treatment processes' inefficiency. To remove from wastewaters, researchers focused on applying immobilized enzymes mild reaction conditions enzyme nontoxicity. Laccases oxidases with wide substrate specificity, capable degradation many different dye types. Laccase Streptomyces cyaneus was expres...

Paint, tannery and textile manufacturing wastewaters contain highly toxic organic biorefractory compounds have adverse effects on human health. These effluents require efficient environment friendly solutions before being discharged. Jar-test experiments are conducted in order to assess the efficiency of a tannin-based polymer (TBP) treatment these industrial wastewaters.The results indicate th...

The photocatalytic degradation of two commercial textile azo dyes, namely C.I Reactive Black 5 and C.I Reactive Red 239, has been studied. TiO(2) P25 Degussa was used as catalyst and photodegradation was carried out in aqueous solution under artificial irradiation with a 125 W mercury vapor lamp. The effects of the amount of TiO(2) used, UV-light irradiation time, pH of the solution under treat...

The biosorption potential of three fungal waste-biomasses (Acremonium strictum, Acremonium sp. and Penicillium sp.) from pharmaceutical companies was compared with that of a selected biomass (Cunninghamella elegans), already proven to be very effective in dye biosorption. Among the waste-biomasses, A. strictum was the most efficient (decolorization percentage up to 90% within 30 min) with regar...
