The brains behind Eskom's operations
Mon, 05 Sep 2016 - 13:15

Professor Alison Lewis and her Crystallization and Precipitation Unit (CPU) team are making news headlines as part of researchers behind Eskom's Eutectic Freeze Crystallization 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).
