Nanofiltration: Membranes, Process Designs, Modules, and Applications

Dear Colleagues,

In recent years, significant advancements in membrane materials and process design have markedly enhanced the performance of nanofiltration (NF) and expanded its application landscape. This Special Issue aims to capture these developments by focusing on next-generation NF membranes, including mixed-matrix and 2D-material-enhanced thin-film composites. These innovations offer improved flux and selectivity, alongside enhanced fouling resistance and chemical stability, enabling operation under more demanding conditions. Contributions addressing process innovations—such as optimized module configurations, hybrid membrane systems (e.g., NF integrated with reverse osmosis or ultrafiltration), and data-driven operational strategies—are particularly welcome, given their role in improving energy efficiency and system reliability. The scope of NF applications has broadened beyond traditional water purification (e.g., drinking water treatment, wastewater reuse, partial desalination) to encompass non-aqueous domains such as organic solvent nanofiltration for chemical and pharmaceutical processing, food and dairy concentration, and resource recovery from industrial streams. This Special Issue seeks to provide a comprehensive overview of current research trends and highlight the latest achievements in membrane development, process designs, and real applications of NF processes.

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 250 words) can be sent to the Editorial Office for assessment.

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.
