Louzanne Coetzee ready to take shot at Paralympics title

For some athletes, the postponement of the Paralympics was a big frustration, but for Louzanne Coetzee it was a ‘blessing in disguise’.

According to the former University of the Free State (UFS) student and current Residence Head of Akasia on the UFS Bloemfontein Campus, she was more than happy to get another 12 months to prepare herself to the very best of her ability. She will be in action at the Tokyo Paralympics in the 1 500 m on Sunday (29 August 2021) and Monday (30 August). On 5 September, she will tackle the marathon. It is her second Paralympics.

“This is the most exited I have ever been for an event. It has been so long since I was able to compete on a high level. I think it is a blessing in disguise. It allowed me more time to prepare. I’m in a great state and I cannot wait,” she said.

In the 1 500 m, Coetzee will be guided by Estean Badenhorst. In the marathon she will run next to Claus Kempen, with whom she has completed a couple of marathons before.

“They are both very experienced and I’m fortunate to have such a great team with me. When you are running an event like the 1 500 m, you need to fully trust your guide with his decision making.”

“The main focus is the track item. I won’t put too much pressure on myself in the marathon. The prime goal is to gain experience in the longer distance, because that is where I’ll be shifting in the future,” she explained.

The South African 1 500 m record holder in the T11 classification (totally blind) clocked a personal best time of 4:51.65 in 2019. She is the world record holder in the 5 000 m; however, the item does not feature on the Paralympic programme.

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.
