Membrane fouling by the high protein concentrations used in biopharmaceutical industry remains poorly understood. In this study, feed of up to 10,000 ppm bovine serum albumin (BSA) were investigated with three polymeric membranes, two which had same molecular weight cut-off (namely, PES100 and PSF100), membrane material PES10). A crossflow ultrafiltration (UF) setup equipped electrical impedanc...

Factors affecting uranium removal from brackish groundwater using a direct solar powered ultrafiltration-nanofiltration/reverse osmosis membrane system were investigated during a field trial in the Australian outback. The key variables were uranium speciation (as a function of pH), groundwater type as well as energy variation over the course of a day. It was found that uranium was retained by t...

An ultrafiltration-based process for oligosaccharide and peptide fractionation from a macroalgae subcritical water hydrolysate was studied. A wide range of separation results obtained depending on the membrane pore. 100 kDa cut-off size enough clarification with total retention colloidal materials. Oligosaccharides present in showed highest all membranes, glucans mostly, followed by galactans, ...

In the presence of selective solvents, amphiphilic block copolymers self-assemble and form different mesomorphic structures, known as mesophases, such as micellar cubic, lamellar, normal/reverse hexagonal, and bicontinuous cubic. Mesophases have been utilized in pharmaceutical and biomedical applications and as template for synthesis of mesoporous material for separation and adsorption processe...

1. The enzyme which decomposes the capsular polysaccharide of Type III Pneumococcus is associated with a protein which under optimal conditions of filtration passes through membranes with an average pore size of 10.6 mmicro but is held back by pores having a diameter of 8.2 mmicro. 2. When enzyme solutions are filtered to dryness through membranes of such porosity as to hold back the active pri...

This investigation indicates the ability to selectively graft glycidyl methacrylate (GMA) only from the external surface of regenerated cellulose (RC) ultrafiltration (UF) membranes using activator generated electron transfer (AGET) atom transfer radical polymerization (ATRP). This controlled polymerization resulted in epoxy functionalized polymer brush ends. Further reaction of the terminal ep...

The most widespread method applied for standardization of milk protein in cheese production isultrafiltration. In the current study, pasteurized, unhomogenized whole milk was ultrafiltered with APVultrafiltration system, 51 spiral wound, polysulfone membrane with 20000 Da molecular weight cut off (DDS,Nakskov, Denmark) at 50 ˚C, such that the pressure difference between the two sides of membran...

Deep seawater is a valuable renewable resource. Due to its outstanding characteristics (i.e., clean, nutrient-rich and cold), deep seawater has been utilized in various subjects, such as mariculture, agriculture, food and beverage, pharmaceutical, medical, and renewable energy. As a result, deep seawater utilization cannot be separated from membrane technologies. Reverse osmosis has become the ...

This study aimed to investigate the performance of composite photocatalytic membranes fabricated by incorporating multiple nanoparticles (TiO2, carbon nanotubes, BiVO4) into polyvinylidene fluoride membrane material for real dairy wastewater treatment. The exhibited superior antifouling behavior, lower filtration resistance, better flux, and higher flux recovery ratio than pristine membrane. Sa...
