The University of the Free State (UFS) will be presenting the fourth panel discussion in the inaugural Thought-Leader Series on the Bloemfontein Campus on 26 July 2018, focusing on the politics of land reform.  

Land reform is a subject of national importance, hence the UFS, as a public higher-education institution in South Africa with a responsibility to contribute to public discourse, seeks to present debates which hold the potential to influence the trajectory of the subject.

The panel discussion on 26 July 2018 follows the launch of the UFS Thought-Leader Series on 12 July 2018, when land reform and human rights, organised agriculture, and food security were discussed by various industry role players, as well as scholars from the UFS.

The programme on 26 July 2018 consists of a welcoming by Prof Francis Petersen, UFS Rector and Vice-Chancellor, after which representatives of the African National Congress (ANC), Democratic Alliance (DA), Economic Freedom Fighters (EFF), Congress of the People (COPE), and the Freedom Front Plus (FF+) will give their views on land reform and expropriation without compensation and whether or not expropriation without compensation is possible without endangering food security and economic growth.

The discussion will be facilitated by Lynette Francis, presenter and producer of the daily news and actuality talk show Praat Saam on RSG and anchor of Fokus on SABC 2.

The programme will start at 09:30 and will take place in the Equitas Auditorium, Bloemfontein Campus.

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.
