In this paper, a comparative study of the treatment of raw and biotreated (upflow anaerobic sludge blanket, UASB) textile dye bath effluent using advanced oxidation processes (AOPs) is presented. The AOPs applied on raw and biotreated textile dye bath effluent, after characterization in terms of COD, colour, BOD and pH, were ozone, UV, UV/H2O2 and photo-Fenton. The decolorization of raw dye bat...

The effect of indigo dye effluent on the freshwater microalga Scenedesmus quadricauda ABU12 was investigated under controlled laboratory conditions. The microalga was exposed to different concentrations of the effluent obtained by diluting the dye effluent from 100 to 175 times in bold basal medium (BBM). The growth rate of the microalga decreased as indigo dye effluent concentration increased ...

Wastewater from seven dye and dye intermediate producing industries and a common effluent treatment plant was assessed to characterize the acute toxicity using Daphnia bioassay. The 24 and 48 h EC50 values and its confidence limits were estimated applying the probit analysis method. The 24 h EC50 values for different dye effluent samples A, B, C, D, E and F were 1.35, 17.32, 17.67, 29.18, 46.49...

dye removal from effluents of textile industries of iran was investigated through biodegradabilitymethod and membrane technology . basic, reactive,disperse and acidic dyes were selected, based onusage rate in iran. the zahen - welenze method (iso 9888) was applied to study the biodegradabilityof dyes. results showed the final cod and dye removal (%r) as (%61,% 57), (%73, %76), (%25, %14),and (%...

Current study has evaluated the decolorization of textile dye Red 3BN by Peniciliium chrysogenum, Cladosporium sp. and Aspergillus niger, isolated from textile industry effluent at Bangalore. The organisms were maintained in the laboratory in Potato Dextrose Agar medium. Production of the enzyme laccase by all the 3 strains of fungi has been confirmed through guaiacol bioassay followed by decol...

a bacterial strain (strain ps) was isolated from the textile effluents carrying serilene black bnfs® (c.i. disp. blk. mix) disperse dye. the isolate was able to decolorize the dye without the need for any exogenous carbon source. full sequencing of its 16s rrna indicated that bacillus sp strain ps is related to bacillus cereus groups.  silica- gel-thin layer chromatography of serilene black dye...

The separation of reactive, sulfur, and vat dyes from cotton dyeing effluent was investigated by a coagulation process using a cationic polymer electrolyte (PE). The coagulation of dyes was found to be considerably influenced by the amount of added PE and pH of the effluent. High degree of separation, (i.e.-90-99%) could be achieved for all the dyes. The secondary treatment of the PE treated (p...

Textile effluent is one of the known sources of pollution, which usually contain several chemicals, which contaminate the receiving water. This study was conducted to understand the ability of Bacillus sp., and Pseudomonas sp., on decolourization and normalization of other physicochemical parameters, such as odour, temperature, pH, total solids, total dissolved solids, total suspended solids, t...

Textile and Textile dyestuff industries discharge effluent having high Chemical Oxygen Demand (COD) and colour, making it difficult to treat the effluent completely. Several Physical, Chemical and Biological treatment methods are available to treat such an effluent. However, in recent year’s biological treatment with focus on bacteria have been drawing a tremendous attention due to their abilit...
