Groepleier: Membraantegnologie
Prof Henning Krieg Henning Krieg het sy B.Sc. En B.Sc. Hons in Suid-Afrika voordat hy op 'n Fulbright-beurs na die VSA in 1994 gereis het waar hy sy M.S. in Chemie aan Rutgers, die Staatsuniversiteit van New Jersey voltooi het. Hy het teruggekeer na Suid-Afrika waar hy sy Ph.D.-graad voltooi het in 2000 aan die Noordwes-…

Agtergrond: Membraantegnologie - Hulpbronveredeling
Suid-Afrika het talle reserwes van verskeie natuurlike hulpbronne. Alhoewel sommige materiale maklik uit hierdie hulpbronne gesuiwer kan word, is ander skeidings beswaarlik moeilik. Byvoorbeeld, Zircon, die belangrikste bron vir Zr wêreldwyd, bevat altyd 'n paar persent van Hf. Die chemiese en fisiese…
Background: Membrane Technology - Resource Benification
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, the most important source for Zr worldwide, always contains a few percent of Hf. The…

H2 Production
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 new and existing membranes are screened for their suitability for this process in terms of…
Process Intensification
Based on past experience on in-house manufactured zeolite coated ceramic membranes, current research is continuing on the use of zeolites and zeolitic membranes combining their catalytic properties as well as their ability to act as molecular sieves. /sites/natural-sciences.nwu.ac.za/files/files/CRB/imagesSintering…
Gas Separation
While gas permeation studies form an intrinsic characterisation tool both for the inorganic as well as organic membranes for various applications, there are ongoing projects focussing specifically on the resolution of various perfluorinated compounds. These projects focus mainly on finding membrane based separation processes to replace…
Background: Membrane Technology
Key Research Areas Research Focus The aim of our research group is to find novel, cost effective and environmentally friendly membrane based separation solutions for industrial as well as rural applications with a specific emphasis on South African relevance. There are two cross-linked key areas of interest within our research…
