The coach of the first women’s hockey team of the University of the Free State is confident that they can do well in the upcoming Varsity hockey tournament.

The competition works on a gender-rotation system every year. This will be the fourth term of Varsity hockey for women. The Kovsie women has a good record. In 2013 they ended fourth, in 2015 they were second, and in 2017 fifth.

The Kovsies will be facing the University of Johannesburg (UJ) on Friday 3 May 2019. On Saturday, the Maties is lying in wait and the North-West University on Sunday.

“I am confident that we will be doing well. If each player plays her role very well, we should reach the semi-final stage. We have put in the hard work, with good progress. We have played three matches so far in 2019 and haven’t been on the losing side yet,” said Luke Makeleni, head coach.

In friendlies last month, the Kovsies drew to NWU (0-0), defeated UJ by 3-1, and had a good win (6-0) against the Johannesburg club, Shumbas.

“We have quite an experienced squad, with seven survivors from the previous Varsity hockey competition (in 2017), so they know what is expected,” Makeleni said. He is in his third year of coaching the women.

The Kovsies have several players with national experience. Simoné Gouws made her debut for the Proteas last year. Casey-Jean Botha, Shindré-Lee Simmons, Antonet Louw, and Lizanne Jacobs have all represented the South African U21 team. Botha is also in the Protea squad. 

■ The Kovsie team: Wiané Grobler, Chane Hartel, Mikayla Claassen, Anke Badenhorst, Casey-Jean Botha, Shindré-Lee Simmons, Esté van Schalkwyk, Nadia van Staden, Antonet Louw, Michelle Ngoetjane, Heraldine Olin, Lizanne Jacobs, Refilwe Ralikontsane, Mielanka van Schalkwyk, Nela Mbedu, Simoné Gouws, Frances Louw, Kia-Leigh Erasmus.

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.
