Special Issue Information

Dear Colleagues, 

The need of clean water for the world is intensifying, driven by population growth, industrialization, rapid urbanization, and climate change. Wastewater refers to all aqueous waste or sewage from homes, hospitals, factories and any other building that uses water in its facilities. Untreated wastewater can have a very negative impact on the environment. The fact that we are making water unusable means that we are literally draining our water supplies. Membrane distillation (MD) has been considered as one of the favorable technologies for the treatment of highly saline wastewater.

We are pleased to invite you to contribute to this special issue entitled "Membrane distillation for wastewater treatment". This special issue will focus on the use of membrane distillation in the treatment of wastewater, such as brine from desalination plants, produced water, municipal wastewater, and industrial wastewater. Also, the membrane development for their application in membrane distillation applications will be included in this issue.  Additionally, innovative investigations on membrane wetting control approaches are welcomed.

Authors are invited to submit their latest original results as full papers or short communications. Furthermore, review articles, case studies and perspective articles are also welcomed and encouraged.

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.

Produced water (PW) generated from hydraulic fracturing operations was treated using an integrated electrocoagulation, ultrafiltration, membrane distillation, and crystallization process (EC UF MDC). The aim was to determine the viability of this integrated process for maximizing water recovery. The results obtained here indicate that optimizing the various unit operations could lead to increased recovery of PW. Membrane fouling limits all membrane separation processes. A pretreatment step to suppress fouling is essential. Here, removal of total suspended solids (TSS) and total organic carbon (TOC) was achieved by electrocoagulation (EC) followed by ultrafiltration (UF). The hydrophobic membrane used in membrane distillation may be fouled by dissolved organic compounds. Reducing membrane fouling is essential to increase the long-term durability of the membrane distillation (MD) system. In addition, combining membrane distillation with crystallization (MDC) can help reduce scale formation. By inducing crystallization in the feed tank, scale formation on the MD membrane was suppressed. The integrated EC UF MDC process can impact Water Resources/Oil & Gas Companies. Conservation of surface and groundwater is possible by treating and reusing PW. Additionally, treating PW reduces the amount of PW disposed in Class II disposal wells and promotes more environmentally sustainable operations. Full article
