The University of the Free State (UFS) has appointed Prof Prince Ngobeni as Principal of the Qwaqwa Campus as from 1 February 2024.

Prof Ngobeni completed his first qualification in Analytical Chemistry at the then Technikon North-West before furthering his studies at the then Technikon Pretoria. He completed a DTech in Chemistry at the Tshwane University of Technology (TUT) in 2003. In 2016, he enrolled for a Doctor of Business Administration in Higher Education at the University of Bath in England. 

His lecturing career began at TUT in 1995 where he progressed from Head of Department: Chemistry in 2003 to Associate Dean: Faculty of Science in 2010, before being appointed as Executive Dean of the Faculty of Sciences at TUT in 2015 – a position he held until 2023. He also served as Interim Campus Rector of TUT’s Pretoria Campus from 2018 to 2020.

“With extensive years of academic leadership experience, Prof Ngobeni has the experience required to guide the Qwaqwa Campus towards the university’s Vision 130. The campus is already recognised as a leader in some of its unique research fields, and Prof Ngobeni’s strong research background will be valuable in this regard,” says Prof Francis Petersen, Vice-Chancellor and Principal of the UFS. 

Prof Ngobeni is a member of several professional bodies in his field of expertise, including MatTEK at the Council for Scientific and Industrial Research (CSIR), the South African Chemical Institute (SACI), the Society for Atomic Spectroscopy, and the South African Council for Natural Scientific Professions (SACNASP). During his career, he has also secured research funding for individual projects and international partnerships. Prof Ngobeni also initiated chemistry practical sessions for local schools and participated in the Technology Station in Chemicals project, which offers a wide range of services designed to assist small and medium enterprises (SMEs) in the chemical sector.

His substantial list of publications in journals and books covers a range of chemistry-related and managerial topics. He is also a well-versed presenter at local and international conferences. 

“The Qwaqwa Campus has experienced major developments in recent years; I look forward to further contributing to the growth of the campus and to support the university in achieving its Vision 130,” says Prof Ngobeni.

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.
