Special Issue Information

Dear Colleagues,

The Special Journal Issue on Ultrafiltration Membranes in Water Treatment addresses a rapidly growing area of water treatmet technology. Ultrafiltration membranes are used to separate small particles and disolved solutes based on size. The utilization of UF water treatment is used for feed pretreatment prior to desalination, wastewater treatment, and it is entrenched in the chemical and pharmaceutical industries, as well as in food and beverage processing. Topics of interest for this Special Issue include but are not limited to predictive modeling of UF separations performance, novel approaches to synthesis of robust (and chemically resistant) UF membranes, UF membranes that overcome the selectivity–permeability tradeoff, low fouling UF membranes, self-adaptive operation of UF membranes, advanced coagulant dosing strategies, surface modification of UF membranes,  module design, and tunning of UF membrane performance. This Special Issue will provide a comprehensive view of UF membranes and their unique place in water treatment. Original research papers are sought for this Special Issue, but critical and informative reviews will also be considered, subject to preapproval by the Editor of the Special Journal Issue of the proposed critical review.

Pretreatment of reverse osmosis (RO) feed water of high mineral scaling propensity was evaluated with respect to downstream RO membrane scaling, for two different feed pretreatment configurations. The pretreatment schemes included (i) media sand filtration, followed by a hydrocyclone (HC) and (ii) a hydrocyclone, microfilter, and a UF module, where both configurations included mesh screens for added protection. The first pretreatment configuration reduced the source water turbidity to ~0.5 NTU, while treatment that included UF feed yielded turbidity of <˜0.1 NTU; both pretreatment strategies provided feed water turbidity within the range recommended for RO desalination. Membrane scaling tests, with the pretreated water without antiscalant dosing, using a plate-and-frame RO unit and a membrane monitoring system, provided real-time membrane surface images that were quantified with respect to the progression of mineral scaling. RO desalting of source water pretreated with the first configuration revealed flux decline that was 75% greater and scale coverage (primarily gypsum) a factor of approximately eight higher relative to desalting of UF-treated source water. The results suggest that RO desalting of high mineral scaling propensity water can significantly benefit from added UF treatment to achieve feedwater turbidity to well below the typically recommended 0.5 NTU upper limit.
