Methods for Enhancing the Energy Efficiency of Water and Wastewater Treatment

Dear Colleagues,

Wastewater treatment represents 0.1% of the energy–water nexus and, as such, any effort expended here would not be expected to yield much of any impact on a geological scale. Despite this, it is a topic much deserving of attention due to a legacy of human innovation in the sector that has been dedicated to safe water for everyone. Today, however, the research attention is shifting to energy. 

Decarbonization of the water sector has started with the optimization of the existing technology. Increasingly ambitious targets have fuelled a technology pipeline that will begin to meet these targets. Naturally, many will fail in the process. Scrutiny over publicly funded research ensures the focus is placed on areas with the best chance of success, thus leading to overall progress.

In researching for this Special Issue, entitled “Methods for Enhancing the Energy Efficiency of Wastewater Treatment”, we have focused on identifying the key processes in the academic and industrial machine sustaining the current progress rate.

This Special Issue will reflect the current state of the pipeline, revealing where a significant impact is being made. In contrast, authors are also invited to submit papers on the current state of mature technology, such as novel contributions made by way of improvements. Together, they will reveal how important continued investment is to meet our ambitions.

Finally, for the areas achieving a high impact, we invite authors to articulate the precise method through which efficiency is enhanced, not limited to a technical scope but also covering the process through which the research presented has arrived at its current state of technology readiness. The scope calls for providing a wide audience with a dynamic reading experience that will make complex technical information easy to consume. From entry-level Ph.D. students seeking a one-stop introduction to their new topic to decision-makers, investors, and the researchers driving innovation, this is a Special Issue worthy of consideration.

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.
