Advanced Oxidation Processes toward Challenges in Contaminants of Emerging Concern Treatment

Dear Colleagues,

Nowadays, drinking water sources are becoming increasingly vulnerable and the demand for municipal and industrial wastewater treatment and reuse is increasing, aiming at circular economy principles. Water scarcity is already driving the urgent need for the improvement of water treatment, especially dealing with the challenges posed by contaminants of emerging concern (CECs) including personal care products and pharmaceuticals, metals, perfluorinated compounds, pesticides, disinfection by-products, microplastics, etc. Recent water treatment research has highlighted the ability of advanced oxidation processes (AOPs) to treat a wide variety of contaminants, going beyond the effectiveness of conventional water treatment technologies.

This Special Issue of Processes highlights the recent progress in the field of groundwater and surface water treatment, wastewater treatment toward water/sewage sludge reuse and energy recovery, and contaminated site remediation. We are pleased to invite you to contribute relevant research articles and reviews focusing on (but not limited to) the following topics:

• Behavior and fate of CECs during the advanced oxidation: reaction kinetics and mechanisms, degradation by-products and toxicological aspects;
• Hydroxyl and sulfate radicals based homogeneous AOPs (O₃/H₂O₂, UV/H₂O₂; UV/persulfate, chlorine-based AOPs, Fenton process);
• Heterogeneous photocatalysis;
• Renewable energy sources and green low-cost materials in AOPs;
• Progress in reactor design and AOPs pilot plant investigation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
