Two athletes, both employees of the University of the Free State (UFS), are now giving back to the sport in administrative roles.

Kesa Molotsane and Louzanne Coetzee are making time in their work and training schedules to serve the sports in which they have represented their country – Molotsane in cross-country and Coetzee in the 1 500 m and 800 m T11 category for athletes with a disability.

Coetzee is again heading for the Paralympic Games in Tokyo. She is a nominee for the International Paralympic Committee Athletes’ Council. Six representatives will be chosen at the Paralympics.

Coetzee was recently elected to the South African Sports Confederation and Olympic Committee Athletes’ Commission. She is also an athlete representative of the South African Sports Association for Physically Disabled.

Molotsane was co-opted into the National Executive Committee of University Sport South Africa as an assessor. She is also the new vice-chairperson of the Athletics South Africa Athletes Commission.

“My biggest dream is to enable athletes to dream big, and for their dreams to be recognised. I would like to see them enjoy their sport,” said Molotsane.

“I think I probably missed a lot of opportunities in my career due to a lack of funding, so I don’t want to see anyone face the same situation.”

Molotsane was also recently named as one of two ambassadors for the SPAR Grand Prix Series. 

According to Coetzee, a former member of the Student Representative Council at the UFS, she believes that it is important for a current sportsperson to contribute and give input in their sport. 

“I enjoy leadership, it is perhaps a gift of mine. Serving the sport in that capacity is not something that is too much of an effort or takes too much of my time. I enjoy contributing and to see something move in a direction.”

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
