In this work, a flow photoreactor was designed and set up using low-cost recyclable parts to develop chemical treatments based on advanced oxidation processes (AOP) of highly colored textile wastewater. To evaluate sustainable system´s efficiency, we investigated compared the performance three types destructive methods (UV/H2O2, Fenton, photo-Fenton) decolorization aqueous solutions Reactive Bl...

This study aiming to determine the optimal conditions degrade an organophosphate pesticide diazinon (DZN) at low levels concentrations (μg.mL−1) and identify by-products generated. The degradation processes utilized were Fenton photo-Fenton. iron concentration [Fe2+], hydrogen peroxide [H2O2], solution pH are investigated parameters. Doehlert three-parameter experimental design was applied mode...

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...

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...

Advanced oxidation processes (AOPs) have been postulated as viable, innovative, and efficient technologies for the removal of pollutants from water bodies. Among AOPs, photo-Fenton shown to be effective degradation various types organic compounds in industrial wastewater. Monometallic iron catalysts are limited practical applications due their low catalytic activity, poor stability, recyclabili...

Submit Manuscript | http://medcraveonline.com the reaction called the Fenton method [1]. Early research on the Fenton reaction was mainly focused on organic synthesis, enzymatic reactions and the cell damage mechanism [2]. It was noted that in the presence of a catalyst, H2O2 can be efficiently decomposed to generate oxidative active substances with strong oxidizing power, and degrade a variety...

The slaughterhouse industry produces large amounts of highly polluted wastewater which needs to be treated before being discharged water. Thus, this work was conducted investigate the feasibility treating using combined chemical coagulation and electro-Fenton methods. We studied effect process parameters such as polyaluminum chloride (PAC) concentration (25, 50, 75, 100 mg/L) for hydrogen perox...

The presence of humic substances as a component natural organic matter (NOM) may cause inefficiency towards drinking water treatment processes, especially the membrane fouling during filtration process. Therefore, to enhance efficiency conventional process, several copper doped Fe-N-C bimetallic heterogeneous Fenton-like catalysts (Cux@FeNC) were prepared and evaluated by executing their cataly...
