several authors have indicated that pcp is a toxic chemical and recalcitrant to biodegradation. aops is one of the moste effective process for degradation of persistant compound.since the mineralization of recalcitrant compound by aops (advanced oxidation processes) often requires long reaction time and strong doses of oxidant, the combination of this process with biological one, considered as ...

Carbon-based functional materials are deemed to be excellent candidates adsorb contaminants from wastewater, yet their catalytic roles in advanced oxidation processes (AOPs) still ambiguous. Therefore, four carbons (SPFCx) were fabricated this study under various pyrolysis temperatures by using Sedum plumbizincicola (SP) residues (a kind of phytoremediation plant) as the precursors. Notably, SP...

Water pollution is a globally recognized serious problem that hindering human development and societal progress. One of the most feasible methods to eliminate this wastewater treatment reuse. Emerging micropollutants, such as pesticides, are notorious for not being removed using traditional methods. Therefore, novel techniques advanced oxidation processes (AOPs) have been proposed, among which ...

<p>This review provides a general overview of the application chemical oxidation to hydrophobic contaminants in form non-aqueous phase liquids (NAPLs). Three types processes, conventional activated persulfate, permanganate, and ozonation, along with three advanced processes (AOPs), Fenton process, photocatalysis, plasma are presented discussed. In addition, this paper brief insight into c...

In this work, we have tested a photocatalytic material consisting of core SiO2/Fe3O4 coated with TiO2 (Magnox) for plausible tertiary wastewater treatment. For this, pilot plant 45 L equipped an Ultraviolet light (UVC) lamp was employed to study the degradation model contaminant, enrofloxacin (ENR), as well water disinfection (elimination Escherichia coli and Clostridium perfringens). The influ...

BACKGROUND Electrochemical methods, as one of the advanced oxidation processes (AOPs), have recently been applied to remove different contaminants from water and wastewater. This study compares the performance of anodic oxidation (AO) and electro-Fenton (EF) methods on waste sludge treatment. METHODS This experimental study was performed on real sludge and the effect of operating parameters s...

One of the major challenges in reusing cooling tower blowdown water (CTBD) utilizing membrane processes is its remaining organic compounds, e.g., humic substances leading to biofouling. Besides, possible abundance chloride CTBD imposes concern formation chlorinated by-products. To choose a pre-treatment process for studied composition, various advanced oxidation (AOPs), including electrooxidati...

As an emerging light source, ultraviolet emitting diodes (UV-LEDs) are adopted to overcome the shortcomings of conventional mercury lamp, such as pollution. The degradation chloramphenicol (CAP) using three UV-LED-based advanced oxidation processes (AOPs)—UV-LED/persulfate (UV-LED/PS), UV-LED/peroxymonosulfate (UV-LED/PMS) and UV-LED/chlorine—was investigated. Results indicate that CAP can be m...

In recent years, advanced oxidation process (AOPs) based on sulfate radical (SO4??) and singlet oxygen (1O2) has attracted a lot of attention because its characteristics rapid reaction, efficient treatment, safety stability, easy operation. SO4?? 1O2 mainly comes from the activation reaction peroxymonosulfate (PMS) or persulfate (PS), which represent reactions involving radicals non-radicals, r...
