Key Points of Advanced Oxidation Processes (AOPs) for Wastewater, Organic Pollutants and Pharmaceutical Waste Treatment: A Mini Review

ChemEngineering, Journal Year: 2022, Volume and Issue: 6(1), P. 8 - 8

Published: Jan. 18, 2022

Advanced oxidation procedures (AOPs) refer to a variety of technical that produce OH radicals sufficiently oxidize wastewater, organic pollutant streams, and toxic effluents from industrial, hospital, pharmaceutical municipal wastes. Through the implementation such procedures, (post) treatment waste leads products are more susceptible bioremediation, less possess load. The basic mechanism produces free other reactive species as superoxide anions, hydrogen peroxide, etc. A classification AOPs is presented in this short review, analyzing processes UV/H2O2, Fenton photo-Fenton, ozone-based (O3) processes, photocatalysis sonolysis chemical equipment points view clarify nature each AOP their advantages. Finally, combined implementations favored through literature an efficient solution addressing issue global environmental management.

Advancement in Ozone base wastewater treatment technologies: Brief review

Ecological Questions, Journal Year: 2022, Volume and Issue: 33(2), P. 1 - 23

Published: Feb. 7, 2022

Over 70% of the planet's surface is covered by water. A universal solvent, water can dissolve a wide variety compounds. The majority contamination caused human activity. Increasing use and pollution are to blame for current shortage fresh supplies. Population expansion, agricultural runoff, municipal wastewater primary sources in river. To conduct study, logical chain was developed. For review, open scientific information were used. focus on publications from last 10 years at same time; earlier works taken into accounts that have useful this which identified list references when studying recent sources. number published than ago does not exceed 7% total references. present study aims determine optimum conditions best removal contaminants as review focuses advancement Ozonation/AOP technology, different type methods used drugs operating condition. Various modern treatment procedures make extensive drinking plants. Water shortages countries be alleviated implementing some recommendations made research. More catchment areas need developed; strict management policies guidelines should implemented. Ozonation also more effectively remove certain personal care products (PPCPs) skin. Recycled disinfected using ozonation, breaks down ozone When way, it an effective parasiticide, germicide, virucidal agent. It chroma compounds, smells, infections, many micro-pollutants simultaneously. Ozone-based AOP studied future see whether cost-effective if consumes energy other traditional methods.

Roles and mechanisms of carbonaceous materials in advanced oxidation coupling processes for degradation organic pollutants in wastewater: a review

Biochar, Journal Year: 2023, Volume and Issue: 5(1)

Published: Dec. 8, 2023

Abstract The widespread organic pollutants in wastewater are one of the global environmental problems. Advanced oxidation processes (AOPs) widely used because their characteristics high efficiency and strong oxidation. However, AOPs may have some defects, such as incomplete mineralization generation toxic by-products during degradation process, thus it is essential to seek efficient green treatment technologies. Coupling different or other beneficial for reduces ecological risks environment. It worth noting that carbonaceous materials (CMs) received attention application water by advanced coupling (C-AOPs) due excellent physicochemical properties recent years. behaviors mechanisms C-AOPs based on CMs still unknown. Therefore, comprehensively summarize research progress. In this review, applications were reviewed first. Secondly, synergistic discussed. Then, intermediates explored important toxicity assessment methods proposed. Finally, potential future challenges This review provides an reference optimization future. Graphical

Recent Advances in Endocrine Disrupting Compounds Degradation through Metal Oxide-Based Nanomaterials

Catalysts, Journal Year: 2022, Volume and Issue: 12(3), P. 289 - 289

Published: March 3, 2022

Endocrine Disrupting Compounds (EDCs) comprise a class of natural or synthetic molecules and groups substances which are considered as emerging contaminants due to their toxicity danger for the ecosystems, including human health. Nowadays, presence EDCs in water wastewater has become global problem, is challenging scientific community address development application effective strategies removal from environment. Particularly, catalytic photocatalytic degradation processes employing nanostructured materials based on metal oxides, mainly acting through generation reactive oxygen species, widely explored eradicate water. In this review, we report recent advances described by major publications years focused several classes EDCs, such plastic components additives, agricultural chemicals, pharmaceuticals, personal care products, were realized using novel oxide-based nanomaterials. A variety doped, hybrid, composite heterostructured semiconductors reported, whose performances influenced chemical, structural well morphological features. Along with photocatalysis, alternative heterogeneous advanced oxidation development, combination may be promising way toward industrial scale application.
