Outstanding Alumni awarded
Attending the awards evening were from the left: Dr Mafu Rakometsi; Gustav Wilson; Dr Pieter du Toit, National Executive Alumni Chairperson; Ace Moloi; Dr Khotso Mokhele; Prof Dave Lubbe; Dr Suzanne Staples; Prof Francis Petersen; Bertus Jacobs, and Tshepo Moloi.
A medical doctor, an economist, an author, and experts in the fields of Information Technology, Education, Management and Sociology are the winners of this year’s Chancellor’s Distinguished Alumni Awards. 

This is the 36th year that the UFS honours those alumni who are not only flying the Kovsie flag high, but are inspiring excellence and transforming lives.

Chancellor’s Challenge

UFS Chancellor Dr Khotso Mokhele had a sobering message for those who attended the awards ceremony on 8 September. He shared how, on a recent visit to the US, he had a chance to visit the campus of Facebook in Seattle, and heard how every year Facebook received more than two million CVs from prospective employees – 98% of whom sported A-average grades. Management then confided in him that they never hired a CV, but rather a mindset.

“They sift through all those applications, looking for someone with a vision to disrupt the status quo,” Mokhele said. “This continent will be left behind if we don’t adopt that mindset – that confidence that borders on arrogance – that we can change the world. Are we ready for that challenge?” 

The recipients in the various categories are:

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.
