Kovsie ACT at the University of the Free State (UFS) is presenting the sixth Kovsie Eco-Vehicle Race this year.

Come and show your support for our students who will be representing our colleges and three campuses, along with the Central University of Technology. Be a part of the action:

Date: Saturday 13 May 2023

Time: 09:00 Performances by student artists

Time: 10:15 Official start of Eco-Vehicle Race

Venue: UFS Odeion School of Music parking area

The Eco-Vehicle Race represents the last phase of a nine-month co-curricular skills programme, providing our students with a set of skills that prepare them for the world of work.

In this programme where students are equipped with basic knowledge and skills on sustainable energy, they get the opportunity not only to race the eco-vehicles, but to also understand the workings of the vehicle, which is critical for repairs done by the team during the race.

Our students will be competing in three events:

Obstacle course: Teams will be challenged by obstacles to test their control over the car.
Smart lap: A timed lap in which the drivers take the main track for the first time.
Endurance race: The teams need to finish as many laps as possible using the least amount of energy in 45 minutes.

The winners of the three events will each receive a trophy. There will be a trophy for the best pit stop as well as a spirit cup for the team with the best energy and support from the audience.

Come and support our students as they showcase their ingenuity and endurance. Don't miss out on the action! For more information, click here to contact Jady Carelse.

Car manufacturers will also exhibit hybrid/electric vehicles; come and view the exhibition and learn more about how these cars work and their benefits.

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.
