Removal of organic pollutants from wastewater by advanced oxidation processes and its combination with membrane processes

Advanced catalytic oxidation coupled to biological systems to treat pesticide-contaminated water: A review on technological trends and future challenges

“…In AOPs -Biological couplings, the importance of the pesticide removal mechanisms lies in the chemical conversion that takes place in the pretreatment with advanced oxidation where the identification and reaction of reactive species are important since they allow understanding the degradation mechanisms of these recalcitrant organic compounds . Likewise, the analysis of the by-products generated provides insight into these degradation mechanisms by identifying the active species during chemical conversion (Titchou et al 2021).…”

“…It has been previously discussed that any advanced oxidation process requires the optimization of its operating parameters to obtain the highest possible mineralizations, generating the non-selective hydroxyl radicals, which attack the organic pesticide and result in the production of CO 2 , H 2 O and inorganic acids or inorganic ions (Poyatos et al 2010;Vagi & Petsas 2020;Titchou et al 2021).…”

Synergetic effect of photocatalysis and peroxymonosulfate activation by CoTiO3/SBA-15, NiTiO3/SBA-15 and Fe2TiO5/SBA-15 for efficient photocatalytic removal of oxytetracycline hydrochloride

“…PMS was activated only by Ni(III) to produce SO 5 ˙−, then SO 5 ˙− radicals reacted with each other to produce SO 4 ˙− (eqn ( 17) and ( 18)). Finally, OTC was mainly degraded by sulfate radicals and holes (eqn (10) Environmental Science: Water Research & Technology Paper 269. Subsequently, SO 4 ˙− and h + continued to disassemble the ring and obtain the compound of m/z = 248.…”

“…As a type of advanced oxidation process, 10 photocatalytic technology has attracted increasing attention in antibiotic wastewater decontamination due to its consistent high-level efficiency. In addition, binary transition metal-based catalysts were relatively attractive compared to monometallic oxides, benefiting from the intensified stability and activity.…”

Grand Challenges in Chemical Treatment of Hazardous Pollutants

“…The tremendous growth in industrialization and urbanization has resulted in generation of large amount of wastewater as well as hazardous waste (Chai et al, 2021;Titchou et al, 2021). Heterogenous solid waste usually ends up in landfills which undergoes various physicochemical change (Xiong et al, 2019;Patel et al, 2021)The nature and composition of hazardous waste varies depending on the source materials.…”
