Although challenging, very exciting and a new journey, says Louzanne Coetzee about the athletics year for which she has been recognised.

The 26-year-old, who is doing her master’s in Social Cohesion and Reconciliation Studies at the University of the Free State, won the Free State Sports Association for the Physically Disabled (FSSAPD) Sports Star of the Year award for a fourth consecutive time. This was for the period June 2018 to April 2019.

In that time, she set a world record, an Africa record, and ran two marathons in which she came amazingly close to a second world record.

Only in her second marathon at the Berlin Marathon in September, the Paralympian fell 26 seconds short of the T11 (totally blind) world record time. She met the qualifying time for the 2020 Paralympic Games in Tokyo during the London Marathon in April.

“Marathons are definitely challenging and a new field for me, but I would say it has been a good 12 months. My aim is now set on next year’s Paralympic Games, where I would like to compete in the marathon and the 1 500 m.”

“I hope to run a good time in the 1 500 m at the World Para Athletics Championships in November.”

At the SASAPD National Championships for physically disabled and visually impaired athletes in April 2019, Coetzee won three gold medals and set a record in the 1 500 m. 

Others from the UFS also honoured

Coetzee has received several awards in her career, but says it is always special to be rewarded by her own federation (FSSAPD). 

Danie Breitenbach (T11) was also honoured as the Senior Male Sports Star. He bagged two gold medals and one silver and set a SA record in both the 800 m and 1 500 m at the nationals. Another Kovsie, Dineo Mokhosoa (F36 – coordination impairments), received a merit award for her gold medal in shot-put and silver in the discus at the national champs.

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.
