The University of the Free State’s (UFS) Prof Hussein Solomon scooped a prestigious Best Published Book award for his critical analysis on the nature of environments, challenges, and opportunities facing the African continent in his book.

Titled African Security in the Twenty-First Century: Challenges and Opportunities, UFS Vice-Rector: Research, Innovation, and Internationalisation, Prof Corli Witthuhn, hailed the book as “An ambitious and in-depth study covering several regions, and with due regard for changing contexts and relevant historical legacies. This analysis is perspicacious, conceptually sophisticated, and based on a solid range of sources.”

UFS awards to stimulate staff creativity

Prof Solomon is a Senior Professor in the Department of Political Studies and Governance. The annual UFS 2018 Book Prize and Research Support Awards is aimed at recognising outstanding contributions by staff members in these focus areas.
Prof Witthuhn congratulated the winners and all the participants who spent time on their submitted work.

The other two entries in the Best Published Book category were Prof Philippe Burger, the Head of the Department of Economics and Finance, for his book titled, Getting it Right: A new economy for South Africa.

The other published book entry was that of Prof Jacobus Naudé, a Senior Lecturer in the Department of Hebrew in the Faculty of the Humanities, titled, A Biblical Hebrew Reference Grammar.

Winning author’s analysis impressive

Prof Witthuhn said the author of the winning book employed a human security approach which not only examined and analysed these challenges, but also assessed the effectiveness of solutions and progress in addressing these challenges.

“This approach is critical to understanding the true meaning and context of security in Africa, by asking questions such as: security for whom and security for what?”

Bouwer comes top in research support category

Ms Annatjie Bouwer, a Research Officer in the Department of Paediatrics and Child Health in the Faculty of Health Sciences, emerged victorious among the nine entrants from various faculties. 

Her award was for the support she offered to the broad community of researchers within the Faculty of Health Sciences.

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.
