Membrane processes allow scalable and energy-efficient separation of gas liquid, advance low-carbon purifications in various industrial environmental applications enable more resilient economy society. In pursuit developing advanced membranes with continuously improved separating performances, nanofillers have been commonly incorporated into to upgrade membrane properties such as mechanical rob...

Rings are common in disk galaxies. These rings are either indistinguishable from a pair of tightly wound spirals, or themselves are a part of the spiral structure. Furthermore, their occurrence is seen coincident with a bar in the center. In this paper, we interpret this spiral-ring structure as density waves resonantly excited by a rotating bar potential. The theory gives excellent agreement f...

Abstract Intense pressure on water resources has led to efforts reuse reclaimed processing wastewater in the food industry. There are tight rules for quality, but efficient separation technologies such as reverse osmosis possess good possibilities reuse. This study developed a membrane-based concept from candy industry emphasizing pre-treatment stage reduce fouling. The contained suspended soli...

A vibrating membrane module currently marketed for ®ltration applications was evaluated for the separation of volatile organic compounds (VOCs) from aqueous solutions by pervaporation. Preliminary screening experiments with three VOCs, three silicone membranes, and in the presence and absence of a surfactant were performed to determine if further consideration of the vibrating module for a ®eld...

Ultra-low pressure gravity-driven membrane (GDM) systems have the potential to be significantly less costly and complex than conventional membranes for water treatment applications. To build upon this inherent advantage, study assesses reuse of recycled in GDM producing drinking water. Two reverse osmosis spiral-wound modules were into nanofiltration (NF)-like ultrafiltration (UF)-like via cont...

Our objective was to measure whey protein removal percentage from separated sweet using spiral-wound (SW) polymeric microfiltration (MF) membranes a 3-stage, 3× process at 50°C and compare the performance of with ceramic membranes. Pasteurized, Cheddar cheese (1,080 kg) microfiltered 0.3-?m polyvinylidene (PVDF) fluoride SW membrane 3×, 3-stage MF process. Cheese making processing were replicat...

Sodium persulfate is a common oxidant used for in situ chemical oxidation (ISCO) remediation of ground water contaminants (e.g., trichloroethylene (TCE)). Following ISCO unused persulfate and oxidation by-products such as sulfates remain within the groundwater at elevated levels. In this laboratory study the performance of three membranes: one nanofiltration (NF) membrane (designated DK) and tw...
