Participants in the third Amazing Race travelled through the African continent, experiencing Africa’s roots and its rich, vibrant, and diverse cultures

During the third Amazing Race presented by Organisational Development and Employee Wellness, staff had the opportunity to virtually travel through Africa. 

The aim of the race with the theme, A Journey through Africa, was to celebrate South Africa and Africa’s roots and its rich, vibrant, and diverse cultures. 

Natasha Nel, organisational development specialist and organiser of the race, says they wanted to give the 13 participating teams the opportunity to explore, learn, create, and be challenged together as they travel to some of the most interesting and exotic locations around Africa, but also in South Africa. 

Here in our own country, teams had the opportunity to experience our culture as well as the diversity of beliefs and traditions.

Interactive and exciting event

Nel says staff could join the race in the convenience of their personal working space via a Zoom meeting. “They only needed to download the game that was specifically tailored for the UFS.” 

“It was a fun, interactive, and exciting event. In this unique adventure, it was interesting to see how teams worked together, made decisions, and also thought outside the box during the challenges,” she says.

Nel explains that teams were requested to take photos, answer questions, and make decisions unique to Africa and their culture. Some decisions and answers were timed. They also had to decide where they wanted to travel, but each decision and option had its costs, reward, and challenge linked to it.

We are the champions

Chanel Lewis, Aneke Kruger, Runé van der Merwe, and Lischen du Randt walked away as winners of the third Amazing Race. 

By participating in this race, the university has sponsored 13 breakfasts for the Community Chest of South Africa (this organisation’s mission is to inspire and facilitate community giving for community enhancement).

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.
