TIA/UFS Platform upscale bioremediation reactors
We have a site where heavy-metal pollution occurs in the groundwater at levels 140 000 times higher than the regulated drinking water standards. We have constructed a 60 kl bioreduction pilot reactor in partnership with Geosyntec Consultants, USA. The reactor is currently treating 21 kl of water with 100% reduction of the metal daily.

January Maintenance and Improvements
Dr Peter Williams visited the site on 12 January 2013 after our metal bioreduction pilot reactor has been in operation for 16 months. Various construction changes have been made during the past year, such as the addition of a polishing reactor to mop up any residual metal which may be present in the bioreactor effluent.

Pitso Matala in the deep mines of South Africa

Hi! I am Pitso Matala and this is my story on venturing into the deep mines of South Africa.

Wow, I am not sure where to begin, but it was quite an experience! The pictures are from my second trip to Star Diamonds mine (Theunissen, Free State). The first thing I noted, was everyone’s commitment to safety. I appreciated the environment and how tough these workers really are. The people were also very friendly and helpful! I am aware that heat can play a crucial role and one must be properly prepared for the descend into the belly of the earth. I was thankful to benchmark my work in Star Diamonds. When I attempt deeper, warmer mine samplings, I will be ready now…..I am ready for action, let’s get sampling.
