After two years of lockdown, online meetings, and limited contact with colleagues, academy at the University of the Free State (UFS) is gradually returning to normal. This month (February 2022), staff, students, and members of related industries will convene on three different occasions to learn about cutting-edge scholarship, to reconnect with each other, and to discuss issues impacting society in the fields of theology, the humanities, and agriculture.

Seminar on ‘The Limits of Decolonisation’ with Prof RW Johnson 

Date: 24 February 2022
Time: 09:00-16:00 SAST
Venue/Platform: Equitas Auditorium, UFS Bloemfontein Campus, and Microsoft Teams 
Microsoft Teams link: https://bit.ly/3Llejew 

Decolonisation has been a heated point of discussion for some time now, but have you ever wondered if there could be limitations hindering the decolonisation project?  The Departments of Political Studies and Governance and Philosophy and Classics at the UFS will host an array of academics and experts for a hybrid seminar on the topic The Limits of Decolonisation.

If decolonisation is an important issue for you or if you are interested in the topic and its relevance and influence in the world and academia, you should join or attend the seminar – either online via Microsoft Teams or in person in the Equitas Auditorium – on 24 February 2022 from 09:00. 

The keynote speaker is political scientist Prof RW Johnson from the University of Oxford. Prof Johnson is an emeritus fellow at Magdalen College and is the author of several acclaimed political books.  The other speakers are all from the Departments of Political Studies and Governance, and Philosophy and Classics. Terrence Corrigan from the South African Institute of Race Relations will speak on The relationship between critical race theory and decolonisation.

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.
