Louzanne and Marné included in national student cross country teams

Two Kovsie athletes, including the blind athlete and world record holder, Louzanne Coetzee, have been included in the national student cross country team.

Coetzee and Marné Mentz will compete at the World Student Cross Country championship on 7 April in St Gallen in Switzerland.

They qualified for the team after good performances at the Athletics South Africa’s cross country trials held at the University of the Free State (UFS) on 20 January. The distance was over 10km.

What makes Coetzee’s inclusion even more remarkable is the fact that she will be competing against able-bodied runners. The world record holder in the 5 000m in her disability category (T-11) and her new guide, Xavier Adams, finished first among the female students in a time of 39:32, which is her personal best. Mentz ended in second place for students in 39:44. They will make up two of the six spots in the women’s team in Switzerland.

First for Coetzee

 It is the first time that Coetzee was chosen for an able-bodied national team. She is doing a master’s degree in Reconciliation and Social Cohesion this year and Mentz is in her final year of a BEd Intermediate Phase.

Tshepang Sello, another Kovsie and an Olympic athlete from Lesotho, took first position for students in 38:04 but did not qualify for the South African team because of her Lesotho citizenship.

Kesa Molotsane (35:29) was the overall winner. Although Molotsane is still doing her honours this year, she ran in the open division as she no longer qualifies as a student because she is over the age of 25, according to University Sport South Africa regulations.

Molotsane ,26, is the national cross country champion of 2016 and obtained second spot last year.

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.
