UFS Creative Clubs

In an ever-changing, increasingly complicated world, the youth must be prepared to bring knowledge and skills to solve issues, make sense of information, and know how to acquire and analyse evidence to make judgements. Science, Technology, Engineering, and Mathematics (STEM) education encourages discussions and problem-solving among students, developing practical skills and an appreciation for collaborations. 

The Social Responsibility Projects department on the UFS South Campus is running a Creative Clubs programme that speaks to STEM education and collaboration.

Opening opportunities 

The primary goal of Creatives Clubs, a MerSETA-funded programme, is to open opportunities to develop problem-solving, critical thinking, and reasoning skills. One aspect Creative Clubs focuses on is identifying potential in the pupil and supporting them in participating in the Eskom Expo for Young Scientists. Learners participate in mathematics, science, and coding activities at the club.

According to Joleen Hamilton, the coordinator and founder of Creatives Clubs, they currently host top-achieving learners in maths from eight schools from Grades 8–12 in Bloemfontein. These schools are split into two groups, which meet at the South Campus on Tuesdays and Thursdays. “We need maths daily, since it stimulates the intellect and aids problem-solving. That’s why, no matter how complicated the sum looks, keep trying and do not give up,” Hamilton said at one of the maths sessions.

Enhancing critical thinking

Matheko Thamae, also a coordinator, mentioned that this programme significantly improves maths and science outcomes for high school learners. “With a dynamic world of innovation and the 4th Industrial Revolution (4IR), the club also assists learners with critical thinking and in solving their communities’ socio-economic issues,” Thamae said. 

“Attending these sessions assists me in thinking out of the box and realising that every problem has a solution. I will continue to attend the programme so that I can find solutions to unresolved problems,” Sechaba Ramakatsa, a Grade 9 learner from Lekhulong Secondary School, said. Ramakatsa, who enjoys assisting others, aspires to be a medical doctor so that people might have better healthcare experiences.

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.
