Fouling of Aluminum Oxide Microfiltration Membranes by Semi-Synthetic Metal Working Fluids
The modeled membrane fouling mechanisms were validated through the reformulation of a semi-synthetic MWF designed to have greater microemulsion stability. It was experimentally verified that the new fluid did not see significant aggregation. Accordingly this fluid did not show evidence of …

Fouling mechanisms in the membrane filtration of single and binary protein solutions
In this study the fouling mechanisms of various microfiltration and ultrafiltration membranes were studied when subjected to crossflow filtration using various protein solutions. Experimentation was carried out using controlled flux experiments and fouling phenomena was investigated via the …

Scale-up of continuous chemical synthesis systems
… in detail. Previous work demonstrated the use of microfiltration membranes to separate liquid-liquid systems by leveraging the dominance of interfacial tension over gravity at small scales. When scaling up, it was determined that pressure control was critical to the operation of the separators. A …

Conductive Membranes for Fouling Mitigation and Permeate Flux Control
… control through conductive modification of the microfiltration membrane, namely coating a layer of conducting polymer on the membrane surface, to improve the function and, subsequently, cost-effectiveness of filtration systems. In this work, a microfiltration membrane was first fabricated by …

Application of electrospun fiber membranes in water purification
Electrospun membranes are attractive for the liquid filtration applications especially as microfiltration membranes because they are low in solidity and have open, highly interconnected porous structures. Nevertheless, liquid filtration processes are pressure driven; hence, it is crucial to …

Design and fabrication of novel nanofiber membranes via electrospinning technique for membrane distillation
… development of suitable electrospun nanofiber membranes for MD. This study mainly focuses on the newly-developed one-dimensional and two-dimensional nano-materials embedded nanofiber membranes, which suffer less wetting issue and have improved water vapor flux performance in MD. It also …

Characterization of microporous ECTFE membranes exposed to different liquid media and ?-radiation and nanoparticle microfiltration through such membranes
Microporous polymeric membranes are used in a variety of applications for separations, purification as well as barrier function. A major application is for microfiltration (MF). Changes in the properties of MF membranes exposed to acids, bases and organic solvents are of interest in semiconductor …

Polymeric Adsorption of Estrone from Water and Photocatalytic Degradation by Zinc Oxide
… high concentrations. Polyamide (Nylon) 6,6 microfiltration membranes were used as a functional polymeric adsorbent to capture low levels of estrone from water. The process is driven by a hydrogen-bonding mechanism between amide groups in polyamide 6,6 and phenolic hydroxyl groups on estrone …
