Advances in Electrochemical Oxidation Technologies for Water and Wastewater Treatment

Dear Colleagues,

Electrochemical oxidation (ECO) processes are advanced oxidation processes with a wide range of applications in the treatment of organic and inorganic contaminants usually found in different wastewater streams. In recent years, electrochemical oxidation has gained increasing interest for the treatment of harmful and recalcitrant organic pollutants, which are typically difficult to degrade with conventional wastewater remediation processes. Numerous publications have claimed that ECO successfully removed large levels of pollutants, while other research found that when utilized as the only treatment method, ECO suffered from a number of issues that limited its application. In order to identify more sustainable and cost-efficient solutions, issues such as cell configuration, energy balance, and electrode material should be reviewed through more research to further optimize the operating parameters. Moreover, research on scaling up the electrochemical oxidation processes is lacking, and researchers are very much encouraged to develop research programmes to fill this gap. Primary data on small- and large-scale systems is therefore important to further develop the different ECO systems. Two lines of ECO investigation are encouraged: the integration of ECO systems into existing treatment systems and the complete replacement of conventional systems.

Authors are invited to submit contributions on the study of electrochemical oxidation, including but not limited to the following topics:

• Electrocoagulation;
• Electroflotation;
• Electrocatalysis;
• Electrochemical oxidation;
• Microbial fuel cells;
• Microbial electrolysis cells.

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 250 words) can be sent to the Editorial Office for assessment.

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. Water is an international peer-reviewed open access semimonthly 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 2600 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.
