Currently, the textile industry is one of the most important economic sectors in many countries. Besides, it is known as a major consumer of water and consequently one of the largest groups of industries causing intense water pollution. Chemicals, including surfactants, dyes, resins, dispersants agents, inorganic salts, etc., play a variety of functions during the textile processing and are pre...

A general overview on the prospective of various oxidation and combined processes in the treatment of tannery industry effluent are reported. Various oxidation and combined processes such as UV/H2O2/Hypochlorites, Fenton and Electro-oxidation, photo-chemical, photo-catalytic, electro-catalytic oxidation, wet air oxidation, ozonation, biological followed by ozone/UV/ H2O2, coagulation or electro...

In recent years, the removal of pharmaceutical and personal care products (PPCPs) from aqueous solutions has been gaining a lot attention researchers throughout world. This is particularly due to concern about their potential hazards toxicities, as they are classified emerging contaminants. Thus, there an increasing need investigate technologies for PPCPs at deeper more holistic level. review a...

The effect of phosphate on adsorption and oxidation of catechol, 1,2-dihydroxybenzene, in a heterogeneous Fenton system was investigated. In situ attenuated total reflectance infrared spectroscopy (ATR-FTIR) was used to monitor the surface speciation at the nano-Fe3O4 catalyst surface. The presence of phosphate decreased the removal rate of catechol and the abatement of dissolved organic compou...

BiFeO₃ particles (BFO) were prepared by a simple hydrothermal method and characterized. BFO was pure, with a wide particle size distribution, and was visible light responsive. Tetracycline was chosen as the model pollutant in this study. The pH value was an important factor influencing the degradation efficiency. The total organic carbon (TOC) measurement was emphasized as a potential standard ...

The mineralisation kinetics of petroleum refinery effluent (PRE) by Fenton oxidation were evaluated. Within the ambit of the experimental data generated, first-order kinetic model (FKM), generalised lumped kinetic model (GLKM), and generalized kinetic model (GKM) were tested. The obtained apparent kinetic rate constants for the initial oxidation step (k'2), their final oxidation step (k'1), and...

Herbicides have been largely utilized during the last decades to maintain quality and quantity of agricultural crop, ensuring need an increasing world food production. However, these synthetic organics are highly biorecalcitrant stable at mild conditions cannot be effectively destroyed in conventional wastewater treatment facilities. Among advanced oxidation processes used remove herbicides, el...

In this study, first of all, removal of dyestuffs from the wastewater ,which is biologically treated but colour removal is not achieved, was investigated by chemical coagulation (FeCl3, FeSO4 and Al2(SO4)3 coagulants), Fenton oxidation (different volume of peroxide and Fe+2) and ozone oxidation(1 gr/h ozone dose) methods. According to the experimental results, maximum color removal efficiencies...

Abstract Fenton or Fenton-like oxidation for treatment of organic radioactive wastes is a promising technology with applications to range wastes. This review details this process; exploring potential challenges, pitfalls and opportunities industrial usage The application process real within pilot-plant settings has been documented, key findings critically assessed in the context future waste pr...

The oxidation of organic compounds and color removal of a synthetic dyeing effluent when treated with a combination of Fenton’s Reagent and biological oxidation in a sequencing batch reactor was evaluated in this work. A central composite design approach was used to find the best conditions of temperature, hydrogen peroxide and ferrous ion concentrations that maximize color and dissolved organi...
