Background: Membrane Technology - Resource Benification
2017-08-31 South Africa has significant reserves of various naturally occurring resources. While some materials can be easily purified from these resources other separations are notoriously difficult. For example, Zircon,…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/resource-benification

H2 Production
2017-01-19 In our group membrane based elctrolyzers are developed for the production of H2 using novel processes like the hybrid sulphur (HyS) process where the hydrogen is produced by the oxidation of SO2 in the presence of water forming H2SO4. Both…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/process-intensification
