Rynardt and Lynique selected for SA team at World Cup
Long jumper Lynique Beneke is one of two Kovsies selected for the South African team to the inaugural Athletics World Cup.

University of the Free State (UFS) middle-distance runner, Rynardt van Rensburg, and long jumper, Lynique Beneke, have both secured a spot in the South African athletics team for the inaugural edition of the Athletics World Cup to be held in London, United Kingdom, on 14 and 15 July 2018. 

The 2018 domestic rankings were used to select the team, with one UFS athlete in each discipline set to represent the country as one of the eight competing nations at the event. Beneke, aged 27, won the long jump for women over the past two years at the national track and field championships, this year with a winning distance of 6,22 m. Van Rensburg, aged 26, won silver.

South Africa will compete against teams from the United States, Poland, China, Germany, France, Jamaica, Great Britain, and Northern Ireland. Beneke and Van Rensburg are both experienced athletes who have competed in the Olympic Games in 2016. The programme for the two-day championship does not include long-distance or combined event disciplines. Yolandi Stander, Van Rensburg, and Beneke have also been selected as part of the preliminary team for the CAA African Championships taking place in Asaba, Nigeria from 1 to 5 August 2018.

Van Rensburg recently clocked his personal best, which was also recorded as the 24th best time of the year, when he finished the Hengelo World Challenge meeting in 1:45.15.
Stander, who has a personal best of 52,81 m, won the bronze medal at this year’s nationals and a silver at the University Sports South Africa (USSA) meeting.

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.
