The objective of this study is to evaluate the turbidity generated during Fenton photo-reaction applied oxidation waters containing carbamazepine as a function factors such pH, H2O2 concentration and catalyst dosage. results let establish degradation pathways main decomposition byproducts. It found that pH affects water. Working between = 2.0 2.5, under 1 NTU due fact iron, added catalyst, in f...

An experimental study on 4-chlorophenol (4-CP) degradation in aqueous solutions by advanced oxidation process photo-Fenton type is presented. The efficiency of the oxidation process is determined by the very high oxidative potential of the OH. radicals generated by catalytic and photo-catalytic processes. The presence of the inorganic species inside the reaction medium influences the rate of th...

This study investigates the degradation of sodium dodecylbenzenesulfonate (SDBS) in aqueous solution by the Fenton-like oxidation process. The effects of different parameters such as concentrations of ferric chloride and hydrogen peroxide, pH and reaction time on the SDBS removal and Chemical Oxygen Demand (COD) reduction were evaluated. Response Surface Methodology (RSM) with Central Compo...

Abstract In this study, refinery wastewater treatment scheme, the electro-Fenton oxidation process is obtainable. Through Fenton treatment, numerous working limits remained examined, for instance hydrogen peroxide, electrolysis time and pH. The effects of variables including pH (2-9), peroxide concentration (20-60 mg/L) reaction (10-30 minutes) thoughtful through means answer surface methodolog...

Phenolic acids constitute a major group of pollutants which are recalcitrant to common biological treatment. In this study synthetic wastewater containing a mixture of p-coumaric and p-hydroxybenzoic acids was evaluated for photo-Fenton pretreatment. The changes in biodegradability (ratio of biochemical oxygen demand to total organic carbon (TOC)) and mineralization (TOC removal) were monitored...

In order to upgrade the quality of anaerobically treated effluent to a level recommended for irrigation, integration of a UASB reactor with UV and AOPs (advanced oxidation processes) (Ozone, H2O2/UV, Fenton, and photo-Fenton) could be a better option for almost complete colour, COD removal, and disinfection of pathogens. High efficiency of the UASB can be maintained by proper process conditions...

The degradation of selected pharmaceuticals in some water matrices was studied by using several chemical treatments. The pharmaceuticals selected were the beta-blocker metoprolol, the nonsteroidal anti-inflammatory naproxen, the antibiotic amoxicillin, and the analgesic phenacetin; and their degradations were conducted by using UV radiation alone, ozone, Fenton’s reagent, Fenton-like system, ph...
