13 September 2019 | Story Cornelius Hagenmeier (Director: UFS International Office)
The management of the University of the Free State (UFS) is deeply concerned about the xenophobic and afrophobic attacks presently occurring in our country. Xenophobia is the ‘fear and hatred of strangers or foreigners or of anything that is strange or foreign’ (Merriam-Webster Dictionary), whereas afrophobia can be understood as the ‘fear and hatred of the cultures and people of Africa’.

The UFS strongly condemns all forms of xenophobic and afrophobic actions and thought and expresses its solidarity with the members of the University community hailing from other regions of the African continent and the world. The UFS is committed to promoting diversity, social justice, inclusivity, and transformation. Its University community is united in its diversity. The UFS cherishes diversity as a catalyst for positive change, innovative research, and cutting-edge teaching and learning. Xenophobic actions, threats or statements will never be tolerated at the UFS. The UFS is committed to nurturing and entrenching a human-rights culture and advocating human rights both within the context of the University and beyond.

Xenophobia, afrophobia and discrimination jeopardise the process of internationalisation at the University. They limit the international and multicultural exposure of our students, which are important to achieve graduate attributes and specifically to develop students’ international and intercultural competence. The UFS is strategically strengthening its collaborations and partnerships in Africa and beyond. It recognises the positive force of diversifying the knowledge paradigms with which it interacts. International staff members, postdoctoral fellows, and students make a significant contribution to the academic project, scholarship traditions, and intellectual diversity of the University. The management of the UFS will do all in its power to ensure the wellbeing of all members of its international University community.

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.
