This study aimed to assess, optimize and model the efficiencies of Fenton, photo-Fenton ozonation/Fenton processes in formaldehyde elimination from water wastewater using response surface methodology (RSM) artificial neural network (ANN). A sensitivity analysis was used determine importance independent variables. The influences different variables, including H2O2 concentration, initial Fe dosag...

A novel electro-Fenton (E-Fenton) process was developed, in which the desired pH for an effective E-Fenton reaction and for a neutral treated media could be obtained by utilizing the reaction-released H+ and OH- in stead of chemical addition. In the laboratory-scale process using three chambers, the substrate solution pH > 4.0 was designed to be adjusted in situ through three sequencing steps: ...

The Fenton process activated by Zero Valent Iron (ZVI-Fenton) is shown here to effectively remove antibiotics reserved for hospital settings (specifically used treat antibiotic-resistant infections) from wastewater, thereby helping in the fight against bacterial resistance. Effective degradation of cefazolin, imipenem and vancomycin real urban wastewater was achieved at pH 5, which quite near n...

Contamination of water often results from the heavy use of agricultural chemicals, and the disposal of aqueous pesticide waste is a concern. Anodic Fenton treatment (AFT) has been shown to be a successful remediation method for pesticides in solution, but the effect of soil on the degradation kinetics of pesticides using this method has not been determined. The purpose of this study was to stud...

13 Alternative conditioning of aluminium-based drinking water treatment sludge 14 using Fenton reagent (Fe 2+ /H2O2) was examined in this study. Focuses were placed on 15 effectiveness and factors to affect such novel application of Fenton process. 16 Experiments have demonstrated that considerable improvement of alum sludge 17 dewaterability evaluated by capillary suction time (CST) can be obt...

Presence of antibiotics in the environment may cause potential risk for aquatic environment and organisms. In this research, Fenton oxidation process was offered as an effective method for removal of antibiotic sulfamethoxazole from aqueous solutions. The experiments were performed on laboratory-scale study under complete mixing at 25±2°C. The effects of initial antibiotic concentration, molar ...

The electrochemical advanced oxidation method “Electro-Fenton” has been applied to remove 17β-estradiol (17β) estra-1,3,5(10)-triéne-3,17-diol) in aqueous-acetonitrile mixture. This endocrine disrupting is a steroid hormone, releases from humans, animals and residual pharmaceuticals into the environmental water and usually causes suspected undesirable effects in aquatic organisms. The degradati...

Oxidation of dilute TCE vapors in a foam reactor using Fenton’s reagent was investigated. The new process relies on rapid mass transfer from the gas undergoing treatment to a fine aqueous foam and oxidation by Fenton’s reagents. Laboratory investigations demonstrated that TCE elimination capacity was as high as 56–61 g TCE m reactorh 1 with a removal efficiency of 62% and TCE mineralization of ...
