UCT's CPU Tweefontein EFC unit
Cutting edge EFC, from theory to reality.
Thursday, August 17, 2017 - 22:45

Thanks to Professor Alison Lewis, Crystallisation and Precipitation Research Unit (CPU) Team and Industrial Partners who have contributed in moving eutectic freeze crystallisation (EFC) from theory to reality. The first full-scale working unit for EFC, which was purchased by Glencore, built and designed by Prentec, is based on research done by CPU staff and students at UCT’s Faculty of Engineering and the Built Environment.

The brains behind Eskom's operations
Monday, September 5, 2016 - 13:15

Professor Alison Lewis and her Crystallisation and Precipitation Unit (CPU) team are making news headlines as part of researchers behind Eskom's Eutectic Freeze Crystallisation Pilot Plant. This cutting edge technology, which is reported to recover about 98% water from liquid effluent discharge streams is located at Eskom's research, testing and development (RT&D). This has got curious minds thinking whether it is 'the solution' for infamous acid mine drainage (AMD).
