Special Issue Information

Dear Colleagues,

This issue focuses on advancing sustainable practices in the management of membranes (reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), forward osmosis (FO), electrodialysis (ED), membrane distillation (MD), fuel cells (FCs), etc.) as they approach the end of their operational life. Synthetic membranes play a crucial role in water treatment, desalination, energy, and various industrial applications, yet their environmental impact and disposal present significant challenges. This collection of articles explores state-of-the-art strategies for membrane reuse and recycling and novel technologies for extending their functional lifespan. Emphasizing circular economy principles and life cycle assessment (LCA), contributors will examine innovative approaches to mitigate environmental footprints and promote resource efficiency in membrane technologies. We invite researchers and practitioners to contribute their expertise, advancing knowledge and solutions for sustainable membrane end-of-life management.

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 2200 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.

The objective of this study is to evaluate the degradation of end-of-life BWRO membranes sourced from a factory in France by analyzing their water permeability, roughness, and chemical composition in order to diagnose the level of degradation incurred during their first life cycle in water softening. Following this, two new applications for the end-of-life BWRO membranes were investigated: (i) as ultrafiltration membranes (UF) for domestic effluent treatment and (ii) as cation exchange membranes (CEM) for use in fungal microbial fuel cells (FMFC). The UF membrane was renovated with an acetic acid treatment and, subsequently, used for domestic effluent filtration. The cation exchange membrane was developed in two steps: (i) chlorine treatment and (ii) the deposition of an Amer Sil layer, a functional coating formed by an interpenetrating polymer network (IPN) made of sulfonated polyether sulfone (S-PES) in a cross-linked matrix of acrylic acid and divinylbenzene.
