What does the best university community look like? And what would a better South Africa look like?

In the last couple of weeks, our conversations have been dominated by topics of violence that have spilled into our communities. We have shared our fears with each other and talked about the complexities that gave rise to this rage within our society. We also witnessed communities pulling together in the midst of the destruction, reminding us of our common humanity. 

If you had the opportunity to help build the best university you could imagine, would you step into that space? If you could help create a prospering South African society, would you act?

This is what the Division of Student Affairs is calling you to do. Join us as we embark on a journey of reimagining and ultimately co-creating the community we want. It starts with a conversation. A conversation where your voice is important and welcomed, and where we regard your presence as essential to realise our shared dreams.

We call you as a member of the UFS community—students and staff alike—to join our circle of conversation. We will make use of deeply engaging methods and break-out rooms to create a safe and brave space that encourages mutual sharing and deep listening. 

Add your vision and voice to the conversation to collectively imagine and build the best version of our university.

UFS Community Conversation
Date: Wednesday, 1 September
Time: 16:00 – 18:00
Platform: Zoom (in order to best support universal access and methodology)

Registration is required:

For reasonable accommodation requirements (e.g., closed captioning, or sign language interpreters), contact Michelle Nöthling at nothlingm@ufs.ac.za.

We also have information session leading up to our main conversation. During these sessions, we welcome your questions and together start to explore the concept of community in a collaborative environment.

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.
