Special Issue Information
Dear Colleagues,
In recent time, there has been a growing interest in responsive membranes for wastewater and water treatment applications. These include electrically conducing membranes (‘electroconductive membranes’) able to couple filtration with electrochemical surface reactions. Typically, electroconductive membranes are fabricated through deposition of a conductive layer (e.g., conductive nanomaterial such as carbon nanotubes or graphene) on conventional polymeric membranes or through synthesis or stand-alone metallic/ceramic membranes.
Electroconductive membranes have been shown to be efficient in multiple water and wastewater treatment applications, including pressure and thermal-driven water filtration (i.e., RO, NF, UF, and MD), and as part of more complex systems such as membrane bioreactors and microbial fuel and desalination cells.
Through applying external potential on the membrane’s surface, electroconductive membranes were shown to mitigate membrane fouling (organic, inorganic, and biofouling), control membrane properties related to transport (i.e., rejection and flux), and also remove/destroy contaminants through electrochemical redox reaction at the membrane surface (i.e., heavy metals and organic matter). Electroconductive membranes were also more recently shown to be efficient in mitigating temperature polarization and flux enhancement of hypersaline solutions as part of a membrane distillation system used for RO brine management.
This Special Issue welcomes papers focused on the latest knowledge and innovations regarding any types of processes using electrically conducing membranes for water and wastewater treatment, including biological, physiochemical, and thermal processes. The papers must show originality and represent a significant contribution to be considered within the scope of the Special Issue.

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. Sustainability 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 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.
