Special Issue Information
Dear Colleagues,
Water scarcity has become a pressing global concern, with wastewater treatment of complex matrices gaining increasing relevance worldwide. Water, an essential and limited resource, is continuously threatened by anthropogenic activities, including domestic, industrial, and agricultural practices, which generate effluents enriched with persistent, emerging, and recalcitrant contaminants. Conventional treatment methods are often insufficient for their complete removal, underscoring the urgent need for robust, innovative, and sustainable technologies to ensure water recovery and reuse.
Within this framework, advanced oxidation processes (AOPs)—including chemical, photochemical, and electrochemical strategies—are emerging as highly promising alternatives for addressing these challenges in real and complex wastewater systems. Their potential to achieve high pollutant mineralization levels, combined with technological advances in materials science and reactor design, positions them at the forefront of modern wastewater remediation research.
This Special Issue in Processes aims to gather contributions from the international scientific community to advance knowledge and foster technological solutions for the sustainable remediation of complex wastewater. We welcome original research articles and comprehensive review papers that address fundamental aspects, applications, and technological innovations in this field.
Topics of interest include, but are not limited to, the following:
- Fenton and photo-Fenton processes
- Heterogeneous photocatalysis
- Electrochemical advanced oxidation processes
- Ozonation processes
- Hybrid and combined treatments
In addition to the application of these technologies, manuscripts highlighting the following aspects will be highly valued:
- Novel reactor design and scale-up approaches
- Development of advanced photocatalytic and electrode materials
- Analytical studies using liquid chromatography, total organic carbon (TOC), and reaction mechanism elucidation
- Cost–benefit analyses and techno-economic assessments
- Integration into circular economy models
This Special Issue seeks to serve as a platform to promote high-impact technological solutions that contribute to sustainable water management, environmental protection, and the responsible use of this critical resource.

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.
