Professor Alison Lewis and CPU Team in the ice lab 2016
The brains behind Eskom's operations

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).

Removing pollution from water

Research based on work done by Professor Alison Lewis and her team in the Crystallisation and Precipitation Unit (CPU) at UCT, is being used at Eskom’s R8.3 million pilot eutectic freeze crystallisation plant. The research, funded by Eskom removes all pollution from the water, solidifies it into pure salts and cleans the water so it can be reused in the power plant.
