Recent Advances in Energies Technologies for Wastewater Treatment

Dear Colleagues,

The growing need for sustainable water management and energy recovery has positioned wastewater treatment at the forefront of circular economy and decarbonization strategies. Traditional treatment processes are often energy-intensive and rely on chemical inputs, whereas recent technological innovations have enabled energy-efficient and even energy-generating treatment approaches.

This Special Issue, “Recent Advances in Energy Technologies for Wastewater Treatment”, will highlight the latest developments in energy technologies, advanced materials, and innovative reactor systems for improving treatment performance, reducing operational costs, and recovering valuable resources.

We welcome contributions that explore both fundamental mechanisms and applied system designs linking wastewater treatment with energy production, conversion, and optimization. Studies combining experimental work, modeling, and life cycle or techno-economic analysis are especially encouraged.

This Special Issue will serve as a multidisciplinary platform to advance our understanding of bioelectrochemical systems, renewable energy integration, and sustainable materials toward the development of energy-positive wastewater treatment processes.

Topics of Interest

Potential topics include, but are not limited to, the following:

• Bioelectrochemical systems (BESs), microbial fuel cells (MFCs), and microbial electrolysis cells (MECs);
• Electrochemical and photoelectrochemical wastewater treatment processes;
• Photocatalysis, electrocatalysis, and nanomaterial-based oxidation technologies;
• Modified electrodes and catalytic materials for enhanced pollutant removal;
• Integration of renewable energy (solar, hydrogen, geothermal, etc.) in treatment systems;
• Hybrid biological–electrochemical and physicochemical treatment configurations;
• Resource recovery (nutrients, hydrogen, methane, metals, etc.) from wastewater;
• Energy-efficient reactor design and process intensification;
• Monitoring, automation, and smart control of energy flows in treatment plants;
• Life cycle assessment (LCA) and techno-economic analysis of energy-orientated systems.

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. Energies 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.
