Special Issue Information

Dear Colleagues,

Membrane technologies have recently emerged as an additional category of separation processes to the well-established conventional processes, and their applications water reclamation, wastewater treatment, water purification, and industrial separations in pharmaceuticals, biotechnology, chemicals, electronics and other sectors. Membrane technologies offer advantages over existing conventional technologies including high selectivity, low energy consumption, high productivity, moderate cost to performance ratio, and compact modular design. Membrane-based hybrid processes combining either a membrane process with a conventional process or another membrane process might be optimal for several applications, and may sometimes achieve separations that are otherwise impractical or impossible to achieve through conventional processes.

Membrane hybrid processes fall into two categories: those combining a membrane process with conventional process, and those combining different membrane processes. Membrane processes may include microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), electro-dialysis (ED), membrane bioreactor (MBR) or per-vaporation (PV), membrane distillation (MD). In the first category, a membrane processes may be combined with conventional processes such as ion-exchange, adsorption (using activated carbon or resins), microbial degradation, air-stripping and several others. In the second, one or more membrane processes are integrated to overcome the problems arising in single membrane processes, and shall include combinations of MF-RO, UF-RO, NF-ED, PV-RO, UF-MD, UF-NF-RO-MD or unique combinations thereof for specific applications. In this regard, new materials and fabrication technologies have been developed and applied to novel membrane synthesis and modification, exemplified by carbon nanotubes-based membranes and nano-composite membranes. Novel membrane processes have been developed with improved membrane materials and designs. These major breakthroughs often lead to greatly enhanced process efficiency arising from permeate flux enhancement, fouling control, and performance improvement.

This Special Issue offers a perfect site to document state-of-the-art developments and innovations in these areas. Authors are invited and encouraged to submit their original papers and reviews.

Submission

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 quarterly 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 300 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Type of Paper: Article
Title: About How to Replace Efficiently the Secondary Clarifier in a Step Sludge Recirculation Reactor by Membranes
Authors: Marco Stoller* and Luca Di Palma
Affiliation: Department of Chemical Materials Environmental Engneering, University of Rome "La Sapienza", Via Eudossiana 18, 00184 Rome, Italy
Abstract: The "hybrid system" consists in the coupling of a step sludge recirculation (SSR) reactor with membranes (replacing the last stage of sedimentation of the biomass more efficiently). The paper will focus on the membrane process, in particular: (1) efficiency to separate bacteria from protozoa from the purified wastewater stream. The separation of the two biological spices is of great advantage since optimized dosage may occur at different stages of the SSR. The discussion will show how the formation of "secondary membranes" by the organic content in the wastewater sticking over the membrane increases this selectivity; (2) membrane fouling. The analysis will follow threshold flux measurements on the system, and how to maintain for long operating times productivity of the membrane, despite the need of limited fouling to increase the selectivity as shown at point 1.
