Intensified Technologies Based on the Fenton Process for Recalcitrant Wastewater Treatment

Dear Colleagues,

We would like to take this opportunity to invite you to participate in a Special Issue on “Intensified Technologies Based on the Fenton Process for Recalcitrant Wastewater Treatment”, which will be published in Processes.

Widely used compounds such as pharmaceuticals, disinfectants, surfactants, personal care products, etc., cannot be properly treated by conventional wastewater treatment processes and are increasingly entering the environment. In many cases, their release can lead to endocrine disruption, acute toxicity, and long-term low-dose exposure, inducing changes in microbial communities that may promote antibiotic resistance development. Thus, there is an urgent need to develop effective and sustainable treatment technologies to remove these recalcitrant pollutants and improve water quality. Fenton’s oxidation stands out due to its simplicity, non-selective nature, and use of low-price and non-toxic reagents. However, some disadvantages limit its practical application. The main drawbacks include the need for a highly acidic environment, the constant loss of iron species, and the generation of iron sludge. To address these concerns, there is ongoing exploration and development of intensified Fenton technologies with the aim of increasing efficiency, lowering operating costs, and reducing chemical consumption and processing time.

This Special Issue on “Intensified Technologies based on the Fenton Process for Recalcitrant Wastewater Treatment” seeks high-quality research and review articles focusing on strategies to intensify the Fenton process and overcome limitations. Potential topics include (but are not limited to):

• Homogeneous Fenton and Fenton-based processes;
• Heterogeneous Fenton-based process;
• Solar photo Fenton and Fenton-based processes;
• Electrochemical Fenton process;
• Bio-electro-Fenton process;
• Combining a Fenton-based process with other treatment technology;
• Innovative reactor design and operation to intensify Fenton-based processes.

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.
