Special Issue Information

Dear Colleagues,

The editorial board of Membranes cordially invites you to submit an article to a Special Issue on "Membrane Processes for Environmental Applications.”

Various membrane technologies are used for environmental applications, including municipal, agricultural, and industrial water and wastewater treatment, water reuse and desalination.

These range from well-established membrane technologies based on pressure-driven separation such as UF, NF, and RO to advanced technologies based on thermal and concentration gradients (MD, FO) as well as electro-membrane separation (ED, EDR, CDI). The development of new technologies elaborates the applicative spectrum of membranes and allows treatment of more complex waste such as high saline water or water containing chemicals of emerging concerns (i.e., micro-pollutants). Furthermore, coupling several treatment technologies including biological process and membrane systems (e.g., membrane bioreactors and microbial desalination cells) has been proven to increase treatment efficiency. Still, these systems suffer from limiting phenomena such as concentration polarization, fouling and high energy consumption.

This Special Issue welcomes both original contributions and mini-reviews related to advanced membranes and their environmental applications. We seek studies that highlight treatment technologies that involve membranes (polymeric, composites, and ceramic) and may also couple bio/electrochemical treatment. Overall, these should be mainly related to desalination, drinking water production, industrial water treatment, water and wastewater treatment, water reclamation in agriculture, remediation, micro-pollutants removal (micro plastics, pharmaceuticals, PFAS), resource recovery and production of high-added value products from wastewater and overcoming limiting phenomena.

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.

This work described the preparation of membranes based on aromatic polysulfones through the phase-inversion method induced by a nonsolvent, generating the phase separation (NIPS) process. Three new techniques, including the nano iron acid etching method, base hydrolysis method of crosslinked polymers, and base hydrolysis method of a reactive component in a binary polymer blend, were developed for pore creation on membranes. The modified polymers and obtained membranes were carefully characterized. The uniform pores were successfully created by base hydrolysis of the crosslinked polymers and obtained at the size of the crosslinker. Moreover, homogeneous pores were created after base hydrolysis of the membranes prepared from binary polymer blends due to the internal changes in the polymer structure. The separation performance of membranes was tested with different inorganic salt solutions and compared with commercially known membranes. These new membranes exhibited high water flux (up to 3000 L/m−2·h−1 at 10 bar and at 25 °C) and reasonable rejections for monovalent (21–44%) and multivalent ions (18–60%), depending on the different etching of the hydrolysis times. The comparison of these membranes with commercial ones confirmed their good separation performance and high potential application for water treatment applications. Full article
