Ultrafiltration Process

Poly(amic acid) prepared from 3,3',4,4'-benzophenonetetracarboxylic dianhydride and bis(4-aminophenyl) ether was used for preparation of microporous membranes by the phase inversion process. Membranes coagulated in acetic anhydride were brittle but usable for ultrafiltration. Coagulation of the poly(amic acid) in water or lower alcohols and subsequent thermal cyclocondensation led to extremely brittle polyimides, which limits their use for ultrafiltration process.

Phase Inversion Process

Low-molecular-mass cut-off tubular ultrafiltration membranes have been developed at the Institute for Polymer Science at the University of Stellenbosch; the compositions and the manufacturing methods are such that these membranes can be made commercially on an industrial scale. Three membranes were designed which gave performances comparable to those of other commercial membranes. The development work comprised detailed studies of the mechanisms of the phase-inversion process, of the solvents and non-solvents used in the gelation step, and of the factors influencing the actual physical production of the membranes. The technology of producing the membranes was successfully transferred to the commercial-scale operation and the membranes have been shown to be economically productive and to show promise in removing colour contamination from natural surface waters and from process streams in the sugar industry.
