In this study, Chemical Oxygen Demand (COD) removal efficiency from wood processing wastewaters by Fenton Process (FP) and Photo Electro (PEFP) were examined. Important operating parameters such as pH, Fe+2 concentration/(amper for PEFP), H2O2 concentration reaction time optimized. Optimum operation conditions of the FP pH 3.5, 1.4 gr/L Fe2+ 50 150 min. while they 3.00, 9.99 mA/cm2 current dens...

Landfill leachate is highly loaded, toxic and is bad for the sanitation of wastewater. In this paper, the treatment of the municipal landfill leachate from Shaoxing landfill was evaluated by using gas-liquid fluidized bed with Fenton reagent. The effects of various operating conditions such as treatment time, initial pH value, initial [H2O2], initial [Fe], and ventilation volume were examined. ...

In recent years, with an increase in the stringent water quality regulations due to environmental concerns, extensive research has focused on upgrading current water treatment technologies and developing more economical processes that can effectively deal with toxic and biologically refractory organic contaminants in wastewater. In this context, in order to avoid or mitigate the possible advers...

In this study, the Fenton process was applied for the degradation of carbofuran from aqueous system. Batch experiments were conducted at two different carbofuran concentrations i.e., 10 and 50 mg/L, and at pH 3. Batch experiments at each carbofuran concentration were designed by central composite design (CCD) with two independent variables i.e. Fe2+ and H2O2. Experimental results indicate that ...

Treatment experiments of a landfill leachate were performed by wet air oxidation (WAO) with the addition of H2O2 (as free radical promoter), and a Fenton-type (at pH 7) process, in order to compare COD (chemical oxygen demand) and AOX (adsorbable organic halogen) reduction as well as biodegradability enhancement measured by OUR respirometric parameter. The WAO reactions were performed in a batc...

Fenton oxidation, an advanced oxidation process, is an efficient method for the treatment of recalcitrant wastewaters. Unfortunately, it utilizes H2O2 and iron-based homogeneous catalysts, which lead to the formation of high volumes of sludge and secondary pollutants. To overcome these problems, an alternate option is the usage of heterogeneous catalyst. In this study, a heterogeneous catalyst ...

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 intensive production of fossil fuels has led to serious polycyclic aromatic hydrocarbon (PAH) contamination in water and soil environments (as PAHs are typical types emerging contaminants). Bio-Fenton, an alternative Fenton oxidation, which generates hydrogen peroxide at a nearly neutral pH condition, could ideally work as pretreatment recalcitrant organics, be combined with the subsequent ...

Selective redox degradation of chlorinated aliphatics by Fenton reaction in pyrite suspension was investigated in a closed system. Carbon tetrachloride (CT) was used as a representative target of perchlorinated alkanes and trichloroethylene (TCE) was used as one of highly chlorinated alkenes. Degradation of CT in Fenton reaction was significantly enhanced by pyrite used as an iron source instea...

In this study, oxidative discoloration of Basic blue3 (B.B3) and Disperse blue56 (D.B56) dyes in synthetic textile wastewater has been studied using Fenton (Fe2+/H2 O2 ) process. The Fenton’s technique showed satisfactory color removal efficiency. The operating parameters such as concentration of Fe2+, dose of H2 O2 , initial concentration of dye, time contact, initial volume of wastewater that...
