Kovsie Eco vehicle parade
A highlight for first-year and senior students is the ACT eco-vehicle building and parade through the streets of Bloemfontein.

Sunny skies, cheerful faces, and an overall great atmosphere surfed the University of the Free State (UFS) Bloemfontein Campus on Saturday, 1 February 2020 for the final series of events in the Kovsie ACT 2020 line-up.

The eco-vehicle parade kick-started the activities for the day and saw various student teams displaying their personalised pit-stop ‘sculptures’ along the streets of Bloemfontein.  UFS residence teams Sonverlief (Houses Sonnedou, Veritas, Madelief); Soetmarmentum (Houses Soetdoring, Marjolein, Armentum); and Beykasium (Houses Beyers Naudé, Akasia, Imperium) came in first, second, and third respectively, obtaining the highest scores out of nine teams for their pit-stop sculpture constructions. 
 
Following the parade, there were a number of fun but competitive eco-vehicle races between the teams. This included the Drag Race, Obstacle Course Race, Formula E Race, Endurance Race, and the Slalom Course Race that took place on the Mokete Square. 

In the evening, students were serenaded by artists such as Early B and Spoegwolf. They danced to performances from the latest Amapiano music sensation, Kabza de Small, and legendary deep-house music duo, Black Motion, at the Rag Farm. 

Assistant Director of UFS Student Life and Director of the Kovsie ACT office, Karen Scheepers, earlier urged students to get more involved in student-life programmes such as Kovsie ACT, in order to equip themselves with a variety of skills and a fulfilling university experience.

A number of senior and first-year students who were part of the action on the UFS Bloemfontein Campus this past Saturday, can attest to Scheepers’ advice.
“I’ve been looking forward to starting university for the longest time, and I am glad that I ended up at the UFS. I don’t feel alone, I feel like I can actually do this,” said first-year Psychology student, Thulisa Shezi.

“University isn’t as bad as everyone thinks it is, it’s just a matter of staying motivated, doing your work, and surrounding yourself with the right people in the process.” – Fourth-year Business Management student, Earl van der Westhuisen.

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.
