Education researchers dominated the recent CTL Excellence in Teaching and Learning Awards on the UFS Qwaqwa Campus.
The Faculty of Education on the Qwaqwa Campus has recently dominated the Centre for Teaching and Learning’s (CTL) Excellence in Learning and Teaching Awards, as well as the Research Awards for 2019/2020. The faculty’s Drs Bunmi Omodan and Maria Tsakeni were placed first and second respectively in the category Research in Teaching and Learning. This was on top of the faculty’s accolade in the category Faculty/Department that is the most involved in Teaching and Learning events and practices on the Qwaqwa Campus.

“The faculty is indeed proud to be associated with these fine scholars and the excellence they represent,” said Faculty of Education Dean,Prof Loyiso Jita, in a congratulatory message to the faculty members.

“To the winners, please continue to live our emerging vision of ‘Representing and using our diversity, excellence in scholarship on research and teaching, and an ethic of care and service’ to produce teachers with balanced knowledge and skills and a consciousness to serve all of society in its diversity,” he added.

Winners from the faculty for the Research Awards were Dr Bekithemba Dube as the Most Prolific Researcher in the Faculty of Education and Dr Sekitla Makhasane in the category Best Emerging Researcher in the Faculty of Education.
It is the first time in years that all four faculties received Learning and Teaching Awards. Institutional awards are scheduled for September 2020.

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.
