The Council of the University of the Free State (UFS) confirmed the following at its meeting on 19 March 2021:


1. Its support of and confidence in the leadership of the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen and his team, and duly recognises the efforts and results achieved at the University during the challenges posed by the COVID-19 pandemic, as well as the current nationwide student protest on the payment of student debt.

2. In this context, the Council also distances itself and deplores the statements made by the leadership of the Institutional Student Representative Council (ISRC), on national television on Monday 15 March 2021,   as it pertained to the demand for the immediate resignation of the Rector and Vice-Chancellor, and the statements pertaining to the Chancellor, Prof Bonang Mohale, and Chairperson of the Council, Dr Willem Louw. The Council notes that Mr Katleho Lechoo, President of the ISRC subsequently retracted the utterances.

3. The Council strongly affirms its confidence in the relationship between the leadership of the UFS and the ISRC and expresses its appreciation for the University leadership’s commitment to continuously engage with students about matters of concern to them. The Council furthermore encourages positive and constructive engagement by the ISRC with the University leadership, as this contributes to shared-understanding of the challenges faced by the South African higher education sector and the governance of the UFS.

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.
