the decolorization of maxilon-red dye by kissiris immobilized phanerochaete chrysosporium in the trickle-bed reactor (tbr) using the basal nitrogen-limited growth medium was studied. the influence of the superficial liquid velocity (slv) on the decolorizing ability of the fungus was examined at four slvs (cm sec-1): 0.05, 0.075, 0.1, and 0.15. maximum level of the decolorizing activity was abou...

Although, synthetic dyes have toxic effects on to environment, are very important for coloration of large number materials and lead increasing concerns about color removal worldwide. Immobilization microorganisms is one the promising techniques biological treatment wastewater with many advantages industrial usage. This study aimed determine efficiency immobilized four different Bacillus species...

this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

Congo red is a synthetic azo-dye dye with many industrial applications. The effluents containing azo dyes are causing several environmental hazards and thus should be treated prior to their discharge. The present work investigates the possible use of a novel microbial consortium from sheep compost for the decolorization of Congo red dye. The effect of different parameters including contact time...

In this study, the Fenton process was used to investigate the color removal efficiency of Acid Red 52 and Basic Red 18 dye solutions by direct chemical oxidation. Color and chemical oxygen demand (COD) was successfully removed more than 99% and up to 92% respectively. This article would provide an easy assessment of the viability of using Fenton reagent in acidic conditions, so it is a prom...
