Special Issue Information

Dear Colleagues,

“The Application of Electrochemical Methods in Water Treatment (AEMWT)” is the title of a Special Issue of Water that is devoted to the interdisciplinary subject of electrochemistry and all aspects related to water and wastewater treatment. The AEMWT focuses on the publication of both original work and reviews in the field of electrochemical treatment. The AEMWT provides the fast dissemination of original articles, reviews, short communications, and full communications, covering the whole field of electrochemical applications in water and wastewater. Short communications are limited to a maximum of 21,000 characters (including spaces), whereas full communications are limited to 26,000 characters (including spaces). We aim to be the fastest published Special Issue in the journal.

AEMWT welcomes the research fields covered by the following areas:

  • Bioelectrochemistry;
  • Combining electrochemistry with other technologies;
  • Computational and theoretical electrochemistry;
  • Electrochemical materials science;
  • Electrochemical methods in carbon sequestration and conversion;
  • Electrochemical sensors in water treatment;
  • Fundamental electrochemistry;
  • Mechanisms of contaminants transformation;
  • Pilot- and full-scale application of electrochemical technology.

The editors would like to draw particular attention to the quality and the scientific content of submissions. Papers must be presented in a way that is accessible to the readers. The presentation and discussion must be at a level that meets the global status of Water.

The AEMWT will not publish papers that have been partially or completely published in other journals or papers that plagiarize other works. All submitted papers are screened for similarity with published works. High similarity will result in rejection without review.

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.

This study investigates performance variation and cell degradation in proton exchange membrane water electrolysis (PEMWE) systems depending on feed water quality. In commercial PEMWE designs, simplified water treatment configurations focusing primarily on electrical conductivity (EC) control are sometimes adopted instead of conventional full ultrapure water production processes. To evaluate the impact of different water treatment processes on cell degradation, permeates from various processes were used as feed water, and cell voltage patterns were analyzed based on EC and total organic carbon (TOC) levels. The experimental results demonstrated that both the two-pass reverse osmosis (RO) and mixed-bed polisher (MBP) permeates achieved an EC below 1 μS/cm, meeting the minimum required standard. Although the cell voltage increase trends for both permeates were similar, the MBP permeate exhibited a higher TOC level despite its lower EC. The elevated TOC level observed in the MBP permeate is attributed to the low organic matter rejection rate of the RO membrane used in the preceding process. This highlights that in simplified water treatment processes for PEMWE, implementing a two-pass RO configuration is essential for effective TOC control. However, simply introducing this configuration is insufficient; it must be accompanied by strategic RO membrane selection to ensure stable operation of PEMWE systems. Full article
