Soccer ladies relish challenge in Potch

The Kovsie women’s soccer team has a tough challenge ahead of them in their quest to reach the semi-finals of Varsity Women’s Football for the first time.

The tournament starts on Thursday 20 September 2018 in Potchefstroom. The Kovsies’ best performance in the competition was in 2016, when they were fifth.

They are in the same group as the University of Johannesburg (UJ), the University of KwaZulu-Natal (UKZN), and Tshwane University of Technology (TUT). TUT has dominated Varsity Women's Football, winning four of the five tournaments. TUT and UJ contested the final last year, as well as the University Sport South Africa (USSA) tournament in July.

Kovsie coach, Godfrey Tenoff, says the challenge of playing the top-seeds is one they relish and welcome.

According to him, the ladies will have gained confidence from USSA where they ended sixth, improving by two places from 2017.

“We were satisfied with our performance at USSA. There are so much the players are capable of, but they don’t get the platform to test their talents as often as the men. We only play UJ and TUT once or twice a year, and there are very few teams in our province with that much talent. So, we have to get out more and find opportunities to play against top-teams to put our preparations and methods to the test.”

“We’ve had a good defence all season, led by our captain, Uma Jakalase. This will have to get us through the tournament.”

* The fixtures: 20 Sept vs UKZN; 21 Sept vs. TUT and UJ. The play-off matches are scheduled for Saturday.

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.
