Special Issue Information

Dear Colleagues,

In the face of the ever-growing severe problem of water shortage, water treatment/purification, including seawater desalination, wastewater reuse, recycling and resource recovery are considered a part of the solution to the problem. Membrane technology has distinct advantages such as simple operation, easy scale-up and no use of chemicals, and thus has been widely used in wastewater recycling, seawater desalination and drinking water treatment. However, the application of membranes in water treatment/purification encounters various unsolved problems, such as membrane fouling.

We are pleased to invite you to submit your latest results (research article and reviews) in the Special Issue on “Membrane Technology: Application in Water Treatment/Purification” of the journal Membranes. This Special Issue aims to seek contributions to assess the state of the art and future developments in the field of membrane technologies in water treatment/purification. Topics include (but not limited to) the following: membrane fabrication and modification, membrane fouling characterization, membrane bioreactor applications, membrane fouling mechanisms, membrane fouling control, drinking water purification, seawater desalination and various wastewater treatments.

I look forward to receiving your contributions.

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.

Humic, protein, and polysaccharide substances have been recognized as significant types of foulants in membrane systems. Despite the remarkable amount of research that has been performed on the interaction of these foulants, particularly humic and polysaccharide substances, with inorganic colloids in RO systems, little attention has been paid to the fouling and cleaning behavior of proteins with inorganic colloids in UF membranes. This research examined the fouling and cleaning behavior of bovine serum albumin (BSA) and sodium alginate (SA) with silicon dioxide (SiO2) and α-aluminum oxide (Al2O3) in individual and combined solutions during dead-end UF filtration. The results showed that the presence of SiO2 or Al2O3 in water alone did not cause significant fouling or a flux decline in the UF system. However, the combination of BSA and SA with inorganics was observed to have a synergistic effect on membrane fouling, in which the combined foulants caused higher irreversibility than individual foulants. Analysis of blocking laws demonstrated that the fouling mechanism shifted from cake filtration to complete pore blocking when the combined organics and inorganics were present in water, which resulted in higher BSA and SA fouling irreversibility. The results suggest that membrane backwash needs to be carefully designed and adjusted for better control of BSA and SA fouling with SiO2 and Al2O3. Full article
