SA joins the ultrafiltration production market

Abstract

Membrane technology Capillary ultrafiltration is arguably the fastest growing filtration technology in the world. The water produced by these types of membranes is said to be of a very high quality, mostly exceeding the quality of water produced by conventional treatment methods. This is achieved without excessive use of chemicals or operator intervention. Ultrafiltration membranes essentially clean water through a ‘sieving’ process. These membranes have extremely small pores (in the nanometre size range), which prevent particles, colloids, microorganisms and dissolved solids that are larger in dimension than the pores in the membrane surface from passing. The membranes therefore act as a physical, size-exclusion barrier. South Afric An product In South Africa, investigations into the possibility of establishing locallyproduced membrane and filtration systems for potable and industrial water management started in the 1990s at the Institute of Polymer Science at the University of Stellenbosch.
