Conference
At the meet-and-greet last night, were from left Prof Ruad Ganzevoort, Diversity Officer and Dean of Theology and Religion at VUA, Prof Francis Petersen and Dr Gene Block, Chancellor of UCLA.

The Unit for Institutional Change and Social Justice at the University of the Free State (UFS) is hosting a colloquium on Fragility and Resilience: Facets, Features and Transformation in Higher Education which started on 29 January, with the official progamme concluding on 30 January 2020.

The colloquium is a annual collaborative partnership between the UFS, University of California, Los Angeles (UCLA), and the Vrije Universiteit Amsterdam (VUA).

Apart from the overarching themes the colloquium also placed some focus on mental health, within this context as all three regions are witnessing a spike in mental health issues among students and staff as well as a deficit in terms of being able to sufficiently address the crisis.

“All three universities are committed to discussing global developments in diversity and transformation in higher education to discussing global developments in diversity and transformation as it may constitute itself in higher education circles around the globe,” says Dr Dionne van Reenen, convener of the 2020 colloquium and research fellow at the unit.  

The idea is to discuss what has and has not worked and, hopefully, access best practices in a variety of contexts. The partnership between the three universities spans over six years starting in 2014 when the UFS first hosted the research colloquium. It is the third time the UFS has hosted the colloquium.
 
Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, along with other members of the UFS Rectorate, attended a meet-and-greet on Monday 28 January 2020, and was joined by Dr Gene Block, Chancellor of UCLA, Vice Provosts Cindy Fan, Patricia Turner, Charles Alexander, Professors Abel Valenzuela, John Hamilton and Dr Shalom Staub, director of Community Learning, as well as Prof Ruard Ganzevoort, Chief Diversity Officer and Dean of Theology and Religion at VUA

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.
