Tennis the bright spark at USSA
The Kovsie Tennis team was crowned as USSA victors for the eighth consecutive time at the recent University Sports South Africa tournament
Even though some Kovsie sport codes came close, it was eventually only the tennis team who were able to grab hold of a gold medal at the various USSA (University Sport South Africa) tournaments taking place in numerous cities across the country during the student winter holidays.

It was the eighth consecutive USSA crown for the Kovsie tennis team. They won all their matches with ease and even the final against Tuks was a one-way affair, winning eight games to one.

The other sport that came close to winning their tournament, was the netball girls. They came unstacked in the final, losing 30-48 to Tuks. It was the first time since 1998 that Kovsies hosted the USSA netball tournament.

The Kovsie female hockey team claimed third spot and the men, playing in the B section, ended second. They only lost once (against the University of KwaZulu-Natal by a single goal), which denied them promotion to the A section.

The Shimlas nearly obtained bronze, but a penalty try for Wits in the closing minutes cost them in the play-off match for 3rd/4th position.

Both the men and women’s football teams ended sixth, but more importantly, the women qualified for the 2019 Varsity football competition. The women improved by two positions and the men by four places from the 2017 tournament.

The table tennis team didn’t have an official final position. They lost in the quarterfinals.

The basketball men ended ninth and the women tenth, improving by ten and six places respectively.

The volleyball men’s team finished in 11th position and the women took 15th spot.

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.
