Physical property and gas transport studies of ultrathin polysulfone membrane from 298.15 to 328.15 K and 2 to 50 bar: atomistic molecular simulation and empirical modelling

Abstract

Pioneering work to elucidate and model the effect of operating conditions on physical and transport properties of ultrathin membranes.

High flux polysulfone braided hollow fiber membrane for wastewater treatment role of zinc oxide as hydrophilic enhancer

“…The high molecular weight of PSf makes this polymer suitable for use in membrane filtrations particularly for water [4,5], pharmaceutical [6], textile dyeing [7,8], desalination [9], peat water [10] and sewage wastewater [11] treatment systems. The excellent mechanical strength, its stability at pH levels from 2 to 13, excellent resistance to caustic and good resistance to moderate chlorine are qualities of PSf which make it suitable to be used for membrane filtration even though it is hydrophobic in nature [5,[11][12][13][14][15][16]. In detail, the excellent mechanical strength ensures the membranes are able to operate at higher pressure, the capability of PSf which can withstand from low to high pH range allows the filtration process to operate at high temperature [6] and the good tolerance to moderate chlorine makes it very suitable for use in any water and wastewater filtration system.…”
