The University of the Free State (UFS) is pleased to announce the appointment of Dr Cias Tsotetsi as the Campus Vice-Principal: Academic and Research on the UFS Qwaqwa Campus as from 1 January 2025.

He is currently Senior Lecturer and Assistant Dean in the Faculty of Education on the UFS Qwaqwa Campus. He holds the following qualifications: BEd(Hons), Postgraduate Diploma in Education, Magister Educationis with specialisation in Policy Studies and Governance in Education, and PhD with specialisation in Philosophy and Policy Studies in Education – all from the UFS.

Dr Tsotetsi operated in the school environment for about 24 years before joining this university in 2010. Since then, he has taught several modules in the Faculty of Education and published several co-authored research articles as well as conference papers on community engagement, teacher development, and participatory action research methodologies, among others. He is also well versed in supervising postgraduate students.

He has received awards from both the university’s Scholarship of Teaching and Learning and the Research committees for his research and academic scholastic performance. He is a member of various committees, such as the Faculty of Education Academic Advisory Board and the Committee for Title Registration and has been participating in partnerships and in NRF-funded projects with peers from universities such as the University of KwaZulu-Natal, the University of Zululand, the Durban University of Technology, and the University of Venda.

“Dr Tsotetsi has a clear understanding of the current systems and operations on the Qwaqwa Campus and is positioned to drive its development. His experience and initiatives involving staff and postgraduate students are exceptional and inspiring. We look forward to Dr Tsotetsi’s valuable contribution to the UFS Qwaqwa Campus and the institution in his new position,” says Prof Prince Ngobeni, Campus Principal of the Qwaqwa Campus.

“I feel honoured to serve the university – and the Qwaqwa Campus in particular – and look forward to working with the campus and its management to develop the research portfolio,” says Dr Tsotetsi.

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.
