Lefébre Rademan, the country’s top student netball player in 2019, has been snatched up by English netball club London Pulse to play in England in 2021.

 

Attempting to become an even better netballer, former Kovsies netball captain Lefébre Rademan decided to jet off to England to play in their league.

Rademan was contracted by London Pulse to compete in the European Superleague in 2021. She will be the fourth Kovsie after Maryka Holtzhausen (2015 and 2018-2019), Karla Pretorius (2016), and Khanyisa Chawane (2020) to play in the league.

Rademan said it was an easy decision, even though it will be far and a long time away from home. The league runs from February to July, with a pre-season in December. She will continue with her master’s degree at the University of the Free State next year.

“I am not going to play netball forever and such an opportunity doesn’t come often. Having competed against England, New Zealand, and Jamaica earlier in the year, I realised they play at a much higher level and if I want to improve and become the best, I would also need to move to a next level.”

“As a goal attack, having Protea teammate Sigi Burger (goal shooter) at the same club, will be an advantage for both of us and for the Proteas as a combination.”

Rademan has had a great past two years, making her Protea debut (12 tests in total) and receiving a number of accolades, such as the Varsity Netball Player of the Tournament in 2019.

In the Telkom Netball League in October, captaining the Free State Crinums, she was named Shooter of the Tournament. She was Player of the Match twice. Her goal average of 88,1% was the highest in the competition.

“Last year was such a good year for me personally, but that remains in the past. You can’t become complacent. I want to keep working hard and become a much better player,” Rademan said.

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.
