Seawater desalination, either through thermal (e.g., multistage flash) or membrane (e.g., reverse osmosis) processes, has become an increasingly important contributor to the world’s freshwater supply. This is true not only for arid regions of the world such as the Middle East and North Africa, but also for semi-arid regions in which the water demand from burgeoning coastal cities has exceeded the sustainable yield under climate changes.
Desalination involves potential environmental impacts. Typical direct impacts include the entrainment and impingement of marine organisms into offshore intakes, or the exposure of organisms to constituents that have been concentrated (e.g., salt) or added through the desalination process (e.g., trace metals or waste heat). So far, many sustainable design features have been successfully developed and implemented to mitigate these impacts. For example, adopting submerged brine outfalls with multiple high-velocity discharge ports at an inclination help reduce the impact concentration, as well as combining brine with other effluents (e.g. wastewater). The use of subsurface seawater intakes and discharge wells can also provide a buffer from the ocean. Yet, ongoing concerns remain in different areas, for example, the direct impacts of mechanical stresses to marine organisms due to the discharges and modifications to the groundwater flow due to subsurface intakes, and the indirect impacts due to increased energy consumption and greenhouse gas emissions caused by the power generation needed for the reverse osmosis (RO) processes. There are ongoing efforts for further improvement, for example reducing brine volume or concentration using novel technology to improve freshwater or energy recovery such as pressure-retarded osmosis, reverse or forward electrodialysis, and ion-concentration polarization.
In this Special Issue, we welcome original research, case studies, and review articles pertaining to these and related topics towards the sustainable design for seawater desalination facilities.

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 papers will be 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. Water is an international peer-reviewed open access monthly 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 1600 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.
