Pilot exchange programme between UFS and University of Wisconsin

The Institute for Reconciliation and Social Justice at the University of the Free State (UFS) partnered with the University of Wisconsin-La Crosse in the United States of America (USA) to pilot the first Global Education student-staff exchange. 

The pilot project hosted seven students from the USA and five students from the UFS in a joint tour. The group delved into the political histories of South Africa, visiting among others Freedom Park, the Voortrekker Museum, the Apartheid Museum, and Mandela House during the first leg of the tour in Johannesburg. Before departing from Johannesburg, they had enriching, thought-provoking round-table sessions with Sello Hatang, Leon Wessels, and some of the staff from the Nelson Mandela Foundation.

En route to Pilanesberg in North-West, the tour visited the Sterkfontein Caves and the Cradle of Humankind at Marupeng. Interactive days at the Mphebatho Cultural Museum and Pilanesberg National Park as well as an excursion to Korannaberg to view some San paintings, provided an opportunity to further survey the place of natural, environmental, and cultural heritage in a globalising, modern world.

JC van der Merwe and Dionne van Reenen were joined by Shirley du Plooy and Matau Setshase, together with La Crosse History Chair, Prof John Grider.

Insightful engagements on diverse issues
In Bloemfontein, the lecturing staff facilitated several full-day classes and dialogues at the UFS, after which students offered enlightening presentations on their insights, and showed some serious and deep engagement with legacies of segregation in many different contexts. 

During the closing evening’s discussions with Prof Francis Petersen, UFS Rector and Vice-Chancellor, staff conveyed that, while they usually expect personally transformative moments during such engagements, there is always hope for real critical developments and deepened understandings of how we see and are seen – students on the tour exceeded this hope by seriously grappling with a large array of social and political challenges and initiating lively, inclusive discussions, debating in their own time and spaces.  
“Education, in all its facets, flourished beyond the classroom for staff, students, hosts, and visitors alike, and both institutions look forward to further collaborations in what promises to be a really productive model for international higher-education exchange programmes,” Van der Merwe 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.
