Gravity Driven Membrane (GDM) Filtration: Fundamentals to Application

Dear Colleagues,

Gravity-driven membrane (GDM) filtration has emerged in the past decade as novel unit operation for water and wastewater treatment/reuse. Valorizing instead of preventing biofilm growth on the surface of ultrafiltration membranes enables stable permeate flux production and improvements in biological stability of the treated permeate. GDM technology is now applied in a variety of different applications, such as reverse osmosis (RO) pre-treatment of seawater, decentralized graywater recycling, and treatment of surface water for potable use. GDM research has elucidated fundamental insights into the structure and function of membrane-based biofilms, which have created translational relevance for best practice approaches to manage biofilms in conventional membrane and water engineering systems (e.g., cooling towers, water distribution networks).

The purpose of this Special Issue on “Gravity-Driven Membrane Filtration: Fundamentals to Application” is to highlight the continued relevance of GDM filtration for basic research and their ubiquitous application. The Special Issue welcomes both original contributions and reviews related to the design, operation, and engineering of biofilms in GDM systems applied to water, wastewater. and graywater treatment/reuse for both centralized and decentralized application. We warmly welcome your submission.

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.
