Abstract: The present invention relates to the production of high flux hollow fiber ultrafiltration membrane prepared from poly(acrylonitrile-co-methacrylic acid), (polysulfone and poly(acrylonitrile-co-methacrylic acid)) and (polysulfone and ion exchange resin (sulfonated polystyrene-divinyl benzene copolymer)) blend and the point-of-use filtration unit there from for water purification and disinfection. The produced membrane has an active layer with pore size which effectively rejects pathogens and other bacteria from contaminated water while allowing the passage of water to produce biologically pure water for drinking. Therefore, the present invention relates to development of hollow fiber ultrafiltration membrane that delivers biologically pure water at a desirable rate, that is at a rate 25-200 liters/m2.h. The membrane performance in terms of flux and rejection efficiency is dependent on polymer material type and surface properties.
