Starting in 2016, UFS Marketing embarked on a project designed to help learners from less fortunate backgrounds to discover their potential. This competition, dubbed ‘Kovsies Star of Stars’, designed to help recognise excellence and reward disadvantaged learners from Quintile 1 to 3 (non-fee-paying) schools. The project’s motto is ‘Aspire to Inspire’, with the goal of discovering the potential hidden beneath the hard-packed surface of poverty.

Two of the five Free State districts were identified, namely Xhariep and Motheo, where the initiative is currently being conducted. In 2016, Grade 12 learners were invited to participate, with ‘Doctor’ Tshepo Thajane, from Lefikeng Secondary School in Botshabelo, being selected as the winner of the inaugural competition. He was pursuing a degree in Actuarial Sciences at the UFS, and towards the end of 2017, he was offered a scholarship to study abroad. This outstanding initiative by the UFS Marketing team was honoured with an award from the organisation Marketing, Advancement, and Communication in Education (MACE) in November 2017.

“We hope to give
… life and hope.”
—Nomonde Mbadi,
Director: UFS Marketing

Initiative seeks to ‘give life and hope’


Nomonde Mbadi, Director of UFS Marketing, whose brainchild the project is, says, “In spite of living in the depths of poverty, taking each day as it comes, these learners have more drive and passion than many others.”

Ms Mbadi and her team, including Chantel Koller, project lead on Star of Stars, aim to "give these learners life and hope" by means of the project, she says.

The winner of the Kovsie Star of Stars for 2017 is Palesa Modutwane from Ipetleng Secondary School in Petrusburg, Free State. She says of her achievement: “This means that all the hard work that I invested in my studies and in community projects is being recognised, and I feel like a new chapter of opportunities has been opened to me. It means that my background does not determine my future. Despite all of this, I still managed to conquer.”

Palesa will be studying Geology at the UFS. After all the hard work getting into her chosen programme, she is up for the challenges and is ready to represent women who were denied the opportunity in a previously male-dominated industry. She says, “I want to show that we have the same potential and wisdom as men.”

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.
