Projections indicate that by 2020 about 80% of all jobs will require some level of competency in Science, Technology, Engineering and Mathematics (STEM). Also, given the rising unemployment rate and the subsequent demand for entrepreneurial skills in the past few years, STEM education has become a priority for South Africa.

A step in the right direction

Equipping young people to be efficient in the world of work and business is a major driver behind the country’s education system. The MEC for Education in the Free State reiterated the importance of STEM subjects. Dr Tate Makgoe addressed about 200 top-performing Grade 12 learners from quintile 1-3 schools in the province who were attending the South African Institute for Chartered Accountants (SAICA) maths camp.

Making mathematics fashionable

The week-long camp recently closed with an awards ceremony which was held on the Bloemfontein Campus of the University of the Free State (UFS). Nine of the creams of the crop of matric learners were honoured for their achievements in mathematics, physical science, and accounting.

Zinhle Gumbi, from Morena Mokopela Secondary School, one of the three Mathematics Top Achiever award recipients has become more determined to choose a maths-related profession. “I have told myself that any career I follow must include maths. Dr Tate Makgoe said we must prove to people that the black child can do it.”

Emerging as one of the Accounting Top Achievers was Albert Ramatsekane from Tsoseletso Secondary School who intends to pursue a Chartered Accountant (CA) qualification. “The camp has boosted my confidence. Now I can choose the CA stream without thinking twice.” 

Sowing the seed and reaping the fruits

Accounting lecturer Mojalefa Mosala was satisfied with the results of the camp. “I am happy to see many familiar faces in my classes who have attended previous camps. It means we’re doing something right.”

Mosala, a former assistant camp organiser, has confidence in the project as it “affords a rare opportunity to learners who have not been exposed to information, the higher learning environment, study skills and motivational figures to experience all of these”. 
Kovsies prides itself in partnering with industry stakeholders to build the future of the country, one maths camp at a time.

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.
