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...

This study makes a comparison between Fenton, Fenton-like, photo-Fenton and photo-Fenton-like treatment methods to investigate the removal of two acid dyes. The two selected acid dyes are C.I. Acid Orange 8 (AO8) and C.I. Acid Red 17 (AR17). These were chosen as model organic contaminants. The effect of operating parameters, such as amount of Fenton’s reagent (H2O2 and Fe) and Fenton’s-like rea...

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...

this study deals with employing foundry sand (fs) as new low cost iron source in heterogeneousphoto-fenton process for the degradation of herbicide isoproturon (ipu) in aqueous solution. thecharacterization of the fs by eds confirmed presence of iron (23%) required for photo-fenton andsimultaneously confirmed absence of any heavy metals which may be susceptible to leaching. the photo-fenton eff...

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...

Many types of advanced oxidation processes (AOPs), namely Fenton (Fe 2+ /H2O2) with different doses, Fenton-like (UV/Fe 2+ /H2O2), photo-Fenton (Fe 2+ /H2O2/TiO2), and plasma technology have been investigated for the removal of organic matters (COD content) from landfill leachate. Fenton's oxidation was the most effective as the most effective ratio 1/10 (Fe 2+ /H2O2) which allow the COD remova...

Background: Pharmaceuticals have arisen as emerging environmental pollutants due to their potential impact on humans, animals and microorganisms even at low concentrations. Conventional wastewater treatment plants are known to be ineffective for removal of many pharmaceuticals present in wastewater. Advanced oxidation processes are one of the most promising treatment technologies for degradatio...

The environmental sustainability of a semi-industrial solar photo-Fenton reactor, treating real effluents emanating from a pharmaceutical laboratory, is assessed herein. The life cycle assessment/analysis (LCA) methodology was employed and real life cycle inventory (LCI) data was collected from a ferrioxalate-assisted homogeneous solar photo-Fenton wastewater treatment plant (WWTP), at Ciudad R...
