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...

Abstract Combining electrocoagulation with another process is a potential strategy for increasing the efficiency of water and wastewater pollutant removal. The integration advanced oxidation processes (AOPs) (EC) demonstrates improved performance. mechanism EC combined ozone (O 3 ), hydrogen peroxide (H 2 O sulfate radicals, electrooxidation (EO), Fenton/electro-Fenton, UV discussed. This revie...

background: recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. reactive dyes are widely used in textile industry. advanced oxidation processes are one of the cost-effective methods for the removal of these dyes. the main aims of this study were determining the feasibility of...

in the last twenty years, due to a number of natural and anthropogenic reasons, many water sources have become poorer in quality with respect to micropollutants. an example of a micropollutant that needs to be removed is the chlorophenoxypropionic herbicide mecoprop (mcpp). mcpp is one of the nine pesticides used as an indicator to monitor pesticide concentrations in rivers because it is freque...

Abstract In the current study, a novel nanomaterial called nanomagnetite/copper oxide/potassium carrageenan nanocomposite (MKCO) was fabricated to include Fenton (nanomagnetite, NM) and Fenton-like reagent (copper oxide nanoparticles, NCO) in matrix of potassium biopolymer. The prepared solid materials were characterized by different physicochemical techniques, such as TGA, N 2 adsorption/desor...

<p>In the current study, three different photo-assisted sources were used to evaluate photo-Fenton oxidation process for pollutant degradation of mature landfill leachate. Solar, UV, and LED visible light photo adopted in this Fenton process. dosages (FeSO4 : H2O2) 1:30, 1.5:30, 2:30, 2.5:30g/L investigation, which was conducted under a variety pH settings (2 3.5) at experimental reaction...

In recent years, the removal of pharmaceutical and personal care products (PPCPs) from aqueous solutions has been gaining a lot attention researchers throughout world. This is particularly due to concern about their potential hazards toxicities, as they are classified emerging contaminants. Thus, there an increasing need investigate technologies for PPCPs at deeper more holistic level. review a...

This study focused on the advanced oxidation of the hetero bi-functional reactive dye Sumifix Supra Yellow 3RF (CI Reactive Yellow 145) using dark Fenton and photo-Fenton conditions in a lab-scale experiment. A 2(3) factorial design was used to evaluate the effects of the three key factors: temperature, Fe(II) and H2O2 concentrations, for a dye concentration of 250 mg L(-1) with chemical oxygen...

To provide new insights toward the selection of the most suitable AOP for isoxazolyl penicillins elimination, the degradation of dicloxacillin, a isoxazolyl penicillin model, was studied using different advanced oxidation processes (AOPs): ultrasound (US), photo-Fenton (UV/H2O2/Fe2+) and TiO2 photocatalysis (UV/TiO2). Although all processes achieved total removal of the antibiotic and antimicro...
