The aim of this study was to find optimum dose of ferrous sulphate and hydrogen peroxide in Fenton oxidation process for treatment of dyeing wastewater. Fenton process is the advanced oxidation method used mainly for COD and colour removal. Experiments are done on synthetic wastewater prepared from three different dyes; acidic, disperse and reactive; and also effluent obtained from industry. Th...

The concept of water footprint (WF) is an important breakthrough in the evolving of methodologies, approaches and indicators for measuring freshwater appropriation and assessing the wastewater discharge. Industrial water footprint (IWF) methodology, which concentrates on the industrial production stages, can present a clear graphic of freshwater consumption and impacts caused by wastewater disc...

Coal combustion by-products (CCPs) contains a certain amount of unburned carbon partcles (~4% to ~30%) without utility way. For utility of unburned carbon, this study tried to make unburned carbon be adsorbent in wastewater treatment. A activation treatment with high temperature had proceed on unburned carbon sample, and effects on adsorptive capability were appeared with results such as the ad...

in this research we have developed a treatment method for textile wastewater by tio2/sio2-based magnetic nanocomposite. textile wastewater includes a large variety of dyes and chemicals and needs treatments. this manuscript presents a facile method for removing dyes from the textile wastewater by using tio2/sio2-based nanocomposite (fe3o4@sio2/tio2) under uv irradiation. this magnetic nanocompo...

Constructing Ag-based photocatalysts by the incorporation of Ag(+) ions into metal/nonmetal oxides for removing organic pollutants is a recently developed strategy, but overcoming their own photocorrosion is still a tremendous challenge. In this work, an advanced Ag-based photocatalyst Ag2Ta4O11 is obtained by this strategy, which exhibits improved photocatalytic activity compared with Ta2O5 an...

textile industry is the major source of water consumption and wastewater pollution.there are various treatment techniques to remove textile wastewater pollution. coagulationflocculation is a widely used process to remove pollution due to suspended particles. in this research, different coagulants like alum, lime, fecl3, feso4 and mgcl2 were applied to select the suitable ones with optimum remov...
