Special Issue Information

Dear Colleagues,

Nanofiltration (NF) and Reverse Osmosis (RO) are increasingly used in drinking water treatment, seawater desalination, wastewater reclamation, and for the production of water for industrial purposes. Significant development has taken place in terms of the fundamental understanding of the transport mechanism in the NF/RO process. Similarly, various methods, such as interfacial polymerization incorporating nanoparticles and other additives, UV grafting/photografting, plasma treatment, and layer-by-layer modification, have been used to fabricate improved NF/RO membranes, which trigger new applications in many industries.

However, there are still several prevalent issues that may hinder the successful application of NF/RO membranes, including concentration polarization, membrane fouling, reverse solute diffusion, and the need for a high-performance membrane design. These challenges are also the current research focus in NF/RO.

Thus, this Special Issue will deliver new insights in the recent advances in NF/RO. We look forward to submissions on innovative research related to the design and applications of NF/RO membranes with lower cost, less energy, and-importantly-minimized environmental impact. Strategies towards NF/RO-concerned fouling control and mitigation are also in the scope of this 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. Membranes 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 2700 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.

Conventional resources of phosphorous are at high risk of depletion in the near future due to current practices of its exploitation, thus new and improved exploration methodologies need to be developed to ensure phosphorous security. Today, some treatment plants recover phosphorous from municipal wastewater as struvite (MgNH4PO4·6H2O). Magnesium is often added to the wastewater as MgCl2·6H2O to facilitate the phosphorous recovery. However, the use of magnesium increases the costs of the process and is not aligned with sustainable development, therefore, alternative magnesium sources have to be found. The current study analyzes the feasibility of integrated membrane processes for magnesium recovery from seawater for utilization in the phosphorous recovery process. The integrated membrane systems consist of nanofiltration (NF), membrane distillation (MD), and membrane crystallization (MCr). The lowest associated cost is found for standalone NF treatment. However, the additional treatment with MD and MCr produces fresh water and salts like NaCl or potentially other valuable minerals at the expense of low-grade heat. Full article
