Recent Advances in Wastewater Treatment Based on Membrane Technologies

Dear Colleagues,

Water pollution is one of the greatest challenges around the world. A major global problem is the rising lack of appropriate quality water supplies. Membrane technology has been accepted as an effective separation process for water and wastewater treatment due to the reliability and efficiency of contaminant rejection, along with the flexibility provided through a range of membrane materials and pore sizes (microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO)).

Membrane filtration processes offer several benefits, including easy operation, monitoring, and maintenance, compact modular construction and smaller footprint, smaller bulk chemical storage tanks and feed facilities, and low chemical sludge effluent. However, like with any other technology, there are obstacles that must be solved to increase the performance of the membrane process.

Recent research attempts have focused on developing polymer-based nanocomposite membranes for sustainable water purification, aimed at enhancing fouling resistance and surmounting the trade-off relationship between permeability and solute rejection. Nanocomposite membranes are a promising modified version of traditional polymeric membranes for water and wastewater treatment, with three main characteristics of enhanced permeation, improved rejection, and reduced fouling. For novel nanocomposite membranes, there is a strong connection between membrane fabrication methods, the properties of fabricated membranes, and membrane performance.

We are seeking high-quality research and review papers on different nanocomposite membrane fabrication and modification techniques for mixed matrix membranes and thin film membranes for both pressure-driven and non-pressure-driven membranes using different types of nanoparticles, carbon-based materials, and polymers. Research contributions on different aspects related to recent advances in wastewater treatment based on membrane technology are welcome to 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 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.
