Azo dyes are widely prevalent environmental contaminants that are recalcitrant to biodegradation processes and have detrimental biological effects. Hence, exploring the novel microbial agents and to develop ecofriendly cost-effective process is pertinent for treatment of textile effluents. A fungal consortium comprising three strains Penicillium oxalicum SAR-3, Aspergillus niger SAR-6 and Asper...

Heavy metals in textile wastewater represent a major environmental problem, and are a potential danger to human health when present on textiles. Furthermore, the presence of some metals influences the production of textiles. Heavy metals are often used as oxidizing agents, as metal complex dyes, dye stripping agents, fastness improvers, and finishers. Thus, they act as hazardous sources through...

This paper examines the use of chemical or electrocoagulation treatment process followed by ion-exchange process of the textile dye effluent. The dye effluent was treated using polymeric coagulant (cationic dye-fixing agent) or electrocoagulation (iron and aluminum electrode) process under various conditions such as various current densities and effect of pH. Efficiencies of COD reduction, colo...

Rapid industrialization and urbanization results in the discharge of large amounts of waste to the environment, which in turn creates more pollution (Senan and Abraham, 2004). Synthetic dyes are extensively used in textile dyeing, paper printing, color photography, pharmaceutical, food, cosmetics and other industries. During textile dyeing, the amount of dye lost in effluent is dependent upon t...

Dyes are one of the most important existing pollutants in textile industrial wastewater. These compounds are often toxic, carcinogenic, and mutagenic to living organisms, chemically and photochemically stable, and non-biodegradable. Acid red 18 is one of the azo dyes that are currently used in the textile industries. Photocatalytic degradation offers a great potential as an advanced oxidation p...

The textile wastewater samples before treatment processes has been collected and characterized using standard methods, in which COD, color and other contaminations are high and prior to remove before discharge. Feasibility of column adsorption of components contributing COD and color onto activated Neem Leaf Powder using sulphuric acid (a-NLP) from textile wastewater has been studied in this in...

In this study; variation of effluent BOD5’s (Se) with reaction time (tr) in Sequencing Batch Reactor (SBR) unit for textile industry wastewater treatment plant and effective parameters on this variation have been researched. Determination of appropriate reaction time (tr) is an important value for design and operation of activated sludge unit. An appropriate kinetic equation for Sequencing Batc...
