Diversity festival
Staff and students come together in celebration at the International Cultural Diversity Festival.


There are 195 countries in the world and the University of the Free State (UFS) officially has a personal relationship with 24 of them. Be it through exchange inbound or outbound programmes or research collaboration, Kovsies is growing its global footprint.

The 2019 International Cultural Diversity Festival brought a mix of music, dance, and poetry to the Bloemfontein Campus on Friday 13 September 2019. The aim of the festival was to recognise, appreciate and celebrate the diverse cultures represented on all our campuses.

Reeling in and rolling out the best talent pool

As stated in the 2018 Internationalisation Report, “Kovsies currently has about 50 international collaboration agreements, and collaboration with 1 584 institutions,” in terms of research. The plan is to widen researchers’ international networks, with a special focus on the African continent.

Finding strength in diversity

“Diversity within groups at the UFS necessitates that we foster a culture of tolerance and a spirit of mutual acceptance and appreciation at our university,” says Chevon Slambee, Chief Officer at the Office for International Affairs (OIA).

Slambee spoke on behalf of the Vice-Rector: Research and Internationalisation, Prof Corli Witthuhn, and the Director of the OIA, Cornelius Hagenmeier, commending the diversity reflected in our international students and staff community.

She mirrored the views of the Kovsie community at large in calling for an end to division and violence based on “othering”. Referring to the upsurge in violence directed against women and people from other countries that we saw in South Africa last month, Slambee remarked: “We are shocked and speechless in light of these events, which are contrary to the spirit of embracing one another’s humanity, which we believe in and want to promote.”

A coming together

The festival theme this year was the Boma which is a traditional space created back in the day where a community would sit around the fire, drumming, singing, dancing and listening to tales told by the elders. The UFS strives to be a similar space – growing the current number of international relationships and immersing the institution in the global village – the African way.

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.
