Membrane development and fabrication for reverse osmosis and ultrafiltration part 4

Abstract

This study formed part of a programme designed to contribute to the development and establishment of ultrafiltration (UF) technology. The four goals of this study can be summarized as follows: i) to establish the technology of laboratory developed membranes for the industrial production of commercially useful tubular ultrafiltration membranes made from poly(ether sulphone). ii) to develop tubular ultrafiltration modules through modification of RO membrane technology which exists at Membratek. iii) to evaluate the membranes and modules in bench and pilot studies on real process streams. iv) to commercialize the technology through the design, construction and commissioning of industrial sized systems. The work proved the following: UF membranes which were developed, showed good integrity and quality when compared to commercial membranes. The materials selected for membrane and module manufacture were current state-of-the-art materials.
