Friends beat the odds by achieving second degrees together

Their friendship began in high school, where they were constantly told by teachers that they would not make it to university, but these best friends never gave up. On Thursday 21 April 2022, they received their honours degrees in the Faculty of Natural and Agricultural Sciences together during the afternoon ceremony of the University of the Free State’s April Graduations.

Lerato Mbongo and Opheleleyo Qwabe, who have been friends since Grade 9, said being picked on in class for not being the brightest learners brought them together and motivated them to work harder.Mbongo obtained a Bachelor of Agriculture Honours majoring in Wildlife Management, and Qwabe received a Bachelor of Agriculture Honours majoring in Agricultural Economics.

“We’ve always dreamed big, but if you had told us back then that we would one day be two-time graduates, we wouldn’t have believed it. During one of our Maths lessons back in Grade 9, our teacher went around asking the ‘smarter’ kids what they wanted to study after matric, but when he got to us, he said there was no point in asking because we wouldn’t make it that far anyway,” Qwabe said.

The friends, who both started at the university’s South Campus, said they were grateful for the UFS Preparation Programme, as it boosted both their marks and their confidence. “The programme helped us to believe in ourselves again, and also played a big role in helping us discover what we wanted to study. The courses we enrolled in really unlocked an unstoppable passion in us and helped us realise that nothing is impossible. Today, here we are celebrating 10 years of friendship, and our honours degrees. We’ve conquered once again, and we're sharing our victories together,” Mbongo 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.
