low-cost grapefruit peel (agricultural waste) was used for removal of reactive blue19 dye fromaqueous solutions. the process was studied as a function of contact time, initial dye concentration andph. adsorption process was attained to the equilibrium within 45 min for initial dye concentrations of 50,75, and 100 mg l-1. an acidic medium was the optimum condition for adsorption of dye at roomte...
The effect of sonochemical reactors (SCR) technology upon the degradation of reactive yellow dye has been studied and reported here. Sonochemical reactors (ultrasound irradiation) produce strong cavitation in aqueous solution causing shock wave and reactive free radicals by the violent collapse of the cavitation bubble. These effects should contribute to destruction as well as the decomposition...
Background and purpose: Due to the poor performance of industrial dye settings about 50% of the washing dye liquor is discharged into the environment. Inappropriate discharge of dye-containing effluents is undesirable because of their color, resistance to biological treatment systems, toxic, and their carcinogenic or mutagenic nature to life forms. In the present study we investigated the photo...
Introduction: The Powdered Activated Carbon Treatment (PACT) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. This study aims to evaluate PACT performance in treating dyes, acid orange, and remazol brilliant reactive blue. Materials and Methods: This empirical- applied research was carried out in pilot scale in which differ...
Ten phenols were selected as natural laccase mediators after screening 44 different compounds with a recalcitrant dye (Reactive Black 5) as a substrate. Their performances were evaluated at different mediator/dye ratios and incubation times (up to 6 h) by the use of Pycnoporus cinnabarinus and Trametes villosa laccases and were compared with those of eight known synthetic mediators (including -...
Background and Aim: Reactive dyes have extensively been used in textile industries during last year's due to their superior performance, but the effluence of the waste containing such dyes into water resources can pose hazardous effects on the environment and to the human health because of their carcinogenic, mutagenic, allergenic and toxic nature. The present research was performed to study th...
A bacterial strain SVM1 with remarkable ability to decolorization textile dye Reactive Red ME4BL was isolated from the activated sludge soil collected from a common effluent treatment plant (CETP) in Perunduari, Erode district Tamil Nadu. Different parameters such as temperature and pH were optimized for decolorization of Red ME4BL by using isolated bacteria. The most promising bacterial isolat...
Background and Objectives: Discharge of textile colored wastewater industries without providing enough treatment in water bodies, is harmful for human and aquatic organisms and poses serious damages to the environment. Most of conventional wastewater treatment methods don't have enough efficiency to remove textile dyes from colored wastewater thus in this research the efficiency of electrocoagu...
The adsorption removal of Triphenylmethane & Xanthene dyes onto a low-cost coal based adsorption (Charfines) and its efficiency in dye colour sorption was compared with activated carbon (F-400). Batch studies were performed and the results revealed that Charfines demonstrated on ability to adsorb the reactive Triphenylmethane & Xanthene dyes. The sorption interaction of reactive dye on to Charf...
