Netball captain rewarded, Chawane gets UK contract

Lefebere and Khanyisa — Lefébre Rademan (left) and Khanyisa Chawane before the start of the Varsity Netball clash. Rademan was named the Player of the Tournament, a reward Chawane received last year.

For the sixth time in the seven years of the competition, the best player in the Varsity Netball tournament hails from the University of the Free State (UFS).

Lefébre Rademan, captain of the Kovsie netball team who ended third in Varsity Netball, was named as the Player of the Tournament and the Players’ Player of the Tournament on Monday night (7 October). Previous UFS recipients of the award are Ané Bester (2013), Karla Pretorius (in 2014 and 2015), Khomotso Mamburu (2016), and Khanyisa Chawane (2018).

Rademan shot 176 goals from 214 attempts for a goal average of 82%. In both the Premier League and National Championship, she received the prize for the best shooter this year.

The news comes shortly after the announcement that a UFS teammate has secured a contract to play overseas next year. Khanyisa Chawane, who impressed immensely as a member of the Proteas at this year’s World Cup, will represent Bath in Europe’s Superleague. The 23-year-old Chawane also received an offer to play in the Australian league, but the one in England suited her better.

She will return to Bloemfontein midway through the year and will still be available for the Kovsie netball team, as she will continue her studies. The talented mid-courter follows in the footsteps of Pretorius, who also spent a season with Bath in 2016.

“I am really thrilled to have signed with Bath. There is no doubt that I’m going to come out a better player; I’m grateful to have been scouted and given this opportunity to play for such a big team. It still brings tears to my eyes when I think about it.”

“My goal has always been to play abroad and to challenge myself. I always strive to better myself and give my best on and off court,” Chawane said about the opportunity next year.

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.
