Female athletes dominate USSA
From left: Marné Mentz (second), Ts’epang Sello (first) and Tyler Beling (third) were in a class of their own, taking the first three spots in the 1 500m at the University Sport South Africa national championship in Sasolburg.

As expected, the Kovsie athletics team made the University Sport South Africa (USSA) national championship, held over the weekend in Sasolburg, one to remember.

Eight athletes earned gold medals, which is twice as many as last year. The total of 24 medals (including seven silver and nine bronze) is also double the number won in 2017. 

They ended third, just one gold medal below the University of Johannesburg. The female athletes won the women’s competition and contributed to seven of the eight gold medals. The Kovsies dominated the 1 500m and 5 000m events in which they both claimed the first, second and third spots. They even grabbed the fourth and sixth position in the 5 000m in which Kesa Molotsane triumphed, with Tyler Beling second, and Marné Mentz third. Mentz and Beling swapped places in the 1 500m behind Ts’epang Sello. 

Molotsane also won the 10 000m in a record time of 34:49.16 which is a massive three minutes and five seconds quicker than the previous record.

The 800m title also now belongs to Sello. She and Beling won a third medal (bronze) as members of the 4 x 400m relay women’s team. 

The other gold medalist was Lara Orrock (3 000m steeplechase), Lynique Beneke (long jump), Esli Lamley (pole vault) and Rynardt van Rensburg (800m).

All five Kovsies who competed at the CAA Southern Region Youth & Junior Championships that took place over the weekend in Boksburg, won medals. They were Pakiso Mthembu (gold, 5 000m), Michaéla Wright (gold, long jump), Tyler (gold, 1 500m), Tsebo Matsoso (silver, 200m) and Orrock (silver, 3 000m steeplechase).

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.
