This research investigated the efficiency of Advanced Oxidation Processes, Enzymatic treatment, and combined enzymatic/AOPs sequences on color remediation of CMP pulp and paper mills effluent. Regarding enzymatic treatment two kinds of fungal enzymes; Laccase (EC: 1.10.3.2) from Terametes Versicolor and Versatile Peroxidase (EC: 1.11.1.7) from Bjerkandera adusta were chosen and applied. Also, t...

The application of the photo-Fenton process for the treatment of wastewaters contaminated with diesel oil was investigated. This particular process has been widely studied for the photochemical degradation of highly toxic organic pollutants. Experiments were performed according to a factorial experimental design at two levels and two variables: H(2)O(2) concentration (5-200 mM) and Fe(2+) conce...

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...

*Corresponding author Email: [email protected] In this work, the treatment of organics present in printing ink wastewaters such as dyes (methylene blue and rhodamine B), surfactants (sodium dodecylbenzene sulfonate), and solvents (ethylene glycol), as well as actual printing ink wastewaters by advanced oxidation processes, namely conductive diamond electrochemical oxidation (CDEO), Fenton...

Although there has been a great deal of research on the structure and function of echolocation calls used for foraging and commuting, relatively little research has been conducted on the communication functions of bat vocalizations (Pfalzer and Kusch, 2003). In addition to echolocation calls, bats produce social calls which differ from echolocation calls in structure and function (Fenton, 2003)...

The Photo-Fenton reaction is an advanced technology to eliminate organic pollutants in environmental chemistry. Moreover, the conversion rate of Fe(3+)/Fe(2+) and utilization rate of H2O2 are significant factors in Photo-Fenton reaction. In this work, we reported three dimensional (3D) hierarchical cobalt ferrite/graphene aerogels (CoFe2O4/GAs) composites by the in situ growing CoFe2O4 crystal ...

Pesticide wastewater has the characteristics of high organic pollutant, high concentration, deep color and high toxicity, which has become difficult to treat the organic wastewater with high concentration at home and abroad. This article uses three methods of US(ultrasonic), Fenton(Fe&H2O2) and combination of US&Fenton were used in the comparative research on the treatment of organic pesticide ...

The applicability of Fenton and photo-Fenton processes as a pretreatment stage to combined wastewater was investigated. The wastewater was obtained from the inlet of the aeration tank in 42 Evler industrial and domestic wastewater treatment plant. The effects of different process variables such as initial Fe2 (c0 8 33 mmol L –1) and H2O2 (c0 65 165 mmol L –1) concentrations, pH (3 7.75) and rea...

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...

Several homogeneous photo-based advanced oxidation processes-namely photolysis, photo-oxidation, and photo-Fenton oxidation—were investigated for the elimination of ibuprofen in water. The effects several operating parameters, such as lamp type (low or medium pressure mercury, xenon-arc), concentration hydrogen peroxide (0.5 to 7 times stoichiometric amount required mineralization), Fenton reag...
