The University of the Free State celebrated the achievements of the Paralympic athlete, Louzanne Coetzee. She won silver and bronze medals at the Paralympic Games in Tokyo.

It is great to be back with her University of the Free State (UFS) family, and Louzanne Coetzee would not have been able to reach her dreams without her Kovsie support.

The Paralympic star thanked the UFS for the role it played in her career and said it was a privilege to represent the UFS and South Africa.

She returned from the Paralympic Games in Tokyo with silver (1 500 m; T11) and bronze (marathon; T12) medals and was welcomed back at a special UFS celebration on 13 September 2021.

The 28-year-old, her guides – Estean Badenhorst and Claus Kempen – and a small group of UFS dignitaries celebrated her achievements.

The Residence Head of Akasia Residence at the UFS not only brought home two medals, but also set a new 1 500 m African record (T11; 4:40.96) and a new world marathon record (T11; 3:11:13) in her class.

Support from home

Coetzee is a UFS alumna who started running while being a Kovsie student.

“Thank you so much for the welcome back,” she said.

“It is great to come back home to my UFS family. Especially after three weeks in another country.”

She said the support messages from the likes of Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, meant a lot while she was in Tokyo.

“I, Claus, and Estean would not have been able to do this without the support of the UFS and Oom DB (Prinsloo; Director of KovsieSport).”

Representing the UFS and the continent

She made special mention of Badenhorst and Kempen, who also run for the Kovsie Athletics Club. “I really feel we function well as a team, and I think the results have been fruitful.”

Prof Petersen praised and thanked them, also for representing the UFS, South Africa, and the continent in such a superb manner.

“You really made us proud as the University of the Free State family, and I know that you will continue with great performances in the future,” he said.

Prinsloo said KovsieSport is immensely proud of the trio and for being UFS ambassadors.

“Thank you very much. We are looking forward to the next couple of years.”

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.
