Student centered community engagement programmes

To help make a change and push for sustainable development, the University of the Free State Division of Student Affairs works with communities around Bloemfontein fostering a culture of creating sustainable solutions.

Gernus Terblanche, Kovsie Support Services and Assistant Researcher in the Division says, ‘it is important for the university to be actively involved in the community as it makes up such a large portion of the Bloemfontein and students also represent many different communities on and off- campus.’

Terblanche said: “As an educational institution it is vital for the UFS to support and guide students towards creating innovative solutions; both local and globally. Our experience is that students often come up with real solutions that can make a real impact in the lives of real people – and it would be crucial to support such initiatives.”

The office has worked with BloemShelter, VermiVillage, GAP Equip, National Hospital and as part of the programmes of 2022 also with Lighuis, Talita Cumi, ROC Kids and the Universitas Neighborhood association. “We are also very fortunate to have, Shanen Emam, Miss Free State 2023 as one of our students that are involved with our programmes,” added Terblanche.

One of the students involved is Prince Sijane, Bloemfontein Campus Student Representative Council member responsible for Civic and Social Responsibility when asked why student participation is important, he said, “By actively participating in initiatives that address social issues or promote community well-being, students become more aware of the challenges faced by society.”

The Division of Student Affairs’ KovsieACT office is also in partnership with the Faculty of Natural and Agricultural Sciences (Department of Sustainable Food Systems and Development) and the Faculty of Health Sciences (Department of Nutrition and Dietetics) to develop and maintain vegetable gardens.

Tereblanche said: “The produce of these gardens addresses hunger and malnutrition amongst students on campus. KovsieACT also facilitates an eco-vehicle project during which student teams learn how to build electric vehicles powered by solar charging stations. This project is aimed at developing skills appropriate to the 4th Industrial Revolution and sustainable resources development including clean and green energy.”

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.
