Composite membranes with nano-sized inorganic materials have high selectivity, hydrophilicity, and improved fouling resistance. Blending Carbon Nanotubes (CNTs) in the polymer solution improves membrane properties like water permeability, The effect of amount, together CNT amount on properties, was investigated this work. There more than 10% increase hydrophilicity 1% addition, but it not alter...

In this study, three types of Al2O3 powders were used as raw materials to fabricate and evaluate the performance all-alumina multi-layer filters, an attempt was made ultrafiltration filter that separates removes proteins. When bovine serum albumin (BSA, molecular weight 66,000) protein, a very high rejection rate 91.9 % obtained even under mild conditions with differential pressure 1 atm or less.

Abstract Transmembrane flux measurements are the only practical tools used to evaluate degree of organic fouling and efficiency chemical cleaning ultrafiltration membranes in situ. Tangential pH-streaming potential profiles may become a comprehensive situ method analyse versus membrane damage. A parallel implementation two methods was assist tuning an efficient protocol for 300 kDa polyethersul...

Abstract Renal Replacement Therapies generally associated to the Artificial Kidney (AK) are membrane-based treatments that assure separation functions of failing kidney in extracorporeal blood circulation. Their progress from conventional hemodialysis towards high-flux (HFHD) through introduction ultrafiltration membranes characterized by high convective permeation fluxes intensified need eluci...

Abstract In this study, statistical analysis was performed to investigate the influence of operational parameters based on experimental results. The research aimed know whether a long-term discontinuous module vibration operation is possible without adversely affecting filtration efficiency. Polymer membranes were compared by surface characteristics with contact angle measurements and selected ...
