First ever netball final in Bloemfontein
The Kovsies will be aiming to lift the Varsity Netball trophy in front of their home supporters on Monday when they face Tuks in the final in the Callie Human Centre.
The netball team of the University of the Free State, once again after five years, earned themselves the right to stage a final in the Varsity Netball competition. The two-time champion, the Dream Team, qualified for the final after topping the log and then wiping the floor with the Maties on Monday (1 October 2018) in the semi-final. The score was 56-45. 

They will come up against Tuks in the Callie Human Centre on the UFS Bloemfontein Campus for the final tonight. The match will get underway at 18:45.

The team won the very first two years of the competition in 2013 and 2014. On both occasions, they had to play away from home – in 2013 against the Pukke in Potchefstroom and in 2014 against Tuks in Pretoria. 

It will be the fourth meeting between the Kovsies and Tuks within three months. The Free State students won the group fixture in August by 68-43, but Tuks had to do without a number of their star players. At the University Sport South Africa tournament in Bloemfontein during July, Tuks triumphed twice, winning the final by 48-30.

Apart from the winners’ medals, an award will be handed to the tournament’s top player. Centre Khanyisa Chawane is one of three finalists. The winner gets chosen through public votes.

Dream Team players have won the prize four of the five times. Ané Botha was crowned in 2013, Karla Pretorius in 2014 and 2015, and last year it was the turn of current Kovsie player, Khomotso Mamburu.

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.
