They came from near and far; the attendees were both from the founding and the contemporary generation – up to the current President, John Macheke. This was reflected in the guest and speaker lists of the colloquium, which was hosted by the Qwaqwa Campus Faculty of the Humanities and the TK Mopeli Library to celebrate the 40th anniversary of the Congress of South African Students (Cosas).

Acknowledging Cosas pioneers

“The two-day colloquium was aimed at enabling all Cosas generations to engage meaningfully, while highlighting the role of its leaders in the struggle for a democratic system of education and country,” said the organiser, Dr Tshepo Moloi from the Department of History.

“We must appreciate the founders of Cosas, as they have not been adequately acknowledged in the democratic dispensation. The organisation fought many battles – one of which was to enable many of us to finally register at institutions of higher learning when it was not as fashionable as it is now,” said Patrick Letsatsi from the Department of Sports, Arts and Culture (DSAC). 

Letsatsi also expressed the DSAC’s mission of facilitating such dialogues on matters of national interest. “Talking enables us to see that burning a library when we need a road is not the right way of dealing with matters,” he said.

Limited research on Cosas

On the academic research front, it is clear that minimal work has been done to reflect on the role played by Cosas over the years. “There is limited scholarly research on Cosas,” said Prof Noor Nieftagodien, the Head of the History Workshop at the University of the Witwatersrand.

“Despite this, we know for a fact that the founding members of Cosas found themselves under serious threat from the state. They were detained almost immediately after its formation in 1979, yet the organisation continued to produce leaders who not only played a pivotal role in the underground movement and formation of youth congresses and trade unions, but also in the shaping of our democratic state,” he argued.

The colloquium also featured Prof Monique Marks, who spoke at length about Cosas in the 1980s and the 1990s. There was also a presentation and photo exhibition by veteran anti-apartheid activist and former member of the Black Sash, Gille de Vlieg, whose photographs back then were inspired by the energy of the students. Other panellists were, among others, founding members Oupa Masuku, Vusi Gqoba, Super Moloi, Titi Mthenjane, and former Free State MEC, Oupa Khoabane.  

The colloquium was hosted in partnership with the national Department of Sports, Arts and Culture and the National Institute for the Humanities and Social Sciences (NIHSS).

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.
