The performance of combined Fenton oxidation and membrane bioreactor (MBR) process for the advanced treatment of an effluent from an integrated dyeing wastewater treatment plant was evaluated. The experimental results revealed that under the optimum Fenton oxidation conditions (initial pH 5, H2O2 dosage 17 mmol/L, and Fe2+ 1.7 mmol/L) the average total organic carbon (TOC) and color removal rat...

Background The recalcitrance of lignocellulosic biomass offers a series of challenges for biochemical processing into biofuels and bio-products. For the first time, we address these challenges with a biomimetic system via a mild yet rapid Fenton reaction and lignocellulose-degrading bacterial strain Cupriavidus basilensis B-8 (here after B-8) to pretreat the rice straw (RS) by mimicking the nat...

The treatment of distillery effluent was investigated experimentally by various advanced oxidation processes such as Fenton and ozone with different combination of UV and H2O2 system. The effect of operating parameters such as hydrogen peroxide concentration, initial effluent pH and Fe concentration on Fenton system for the percentage color and chemical oxygen demand removal has been studied. T...

Alternative conditioning of aluminium-based drinking water treatment sludge using Fenton reagent (Fe2+/H2O2) was examined in this study. Focuses were placed on effectiveness and factors to affect such novel application of Fenton process. Experiments have demonstrated that considerable improvement of alum sludge dewaterability evaluated by capillary suction time (CST) can be obtained at the rela...

Decolorization of sunset yellow dye (SY) in an aqueous solution was investigated by Fenton reaction using H2O2/Fe 2+ system. Different parameters controlling the degradation efficiency as pH and H2O2 and Fe 2+ concentrations were evaluated. The optimal operational conditions were found to be [Fe] = 2.55x10 mmol, [H2O2] = 0.2425 mmol at pH 2.7. The study of the Kinetics of decolorization indicat...

BACKGROUND The potential genotoxic activity associated with high strength real paracetamol (PCT) wastewater (COD = 40,000 mg/L, TOC = 12,000 mg/L, BOD5 = 19,320 mg/L) from a large-scale drug-producing plant in the Marmara Region, was investigated in pre- and post- treated wastewater by the Fenton process (COD = 2,920 mg/L, TOC = 880 mg/L; BOD5 = 870 mg/L). METHODS The SOS Chromotest, which is...

The performance of a new electro-Fenton process with Ti-based mixed metal oxides (Ti/MMO) cathode, a dimensionally stable electrode, is evaluated for degrading contaminants of emerging concerns (CECs) in aqueous solutions. Bisphenol A (422μgL(-1)) is completely degraded in an undivided cell using Ti/MMO as the cathode in the presence of 6.9mgL(-1) Fe(2+) within 20min under conditions of pH 4 an...

The three-dimensional electro-Fenton method was used in the folic acid wastewater pretreatment process. In this study, we researched the degradation of folic acid and the effects of different parameters such as the air sparging rate, current density, pH and reaction time on chemical oxygen demand (COD) removal in folic acid wastewater. A four-level and four-factor orthogonal test was designed a...
