Countdown to music, art and fun as Kovsie ACT festival approaches
Kovsie students in the process of building their Eco vehicles

The countdown has begun to the Kovsie-ACT music festival that will take place on 17 February 2018 at the Cross Country Fields.

With just a few days left before the main event where students and the community will be wowed by performances from the likes of Prince Kaybee, Jack Parow and Shekinah, students can look forward to the "Social Cohesion" college festivities namely: the West College Project Neon party, East College Graduation party, Central College Yellow party, South College Feballoween party, North College Cowboys and Crooks party, and finally the Kovsie-ACT Fiesta Mexican party.

Each day leading up to the main event, senior on-campus residence students will be working on the building of their various Eco vehicles. Students will be grouped in their designated colleges at the UFS Rag Farm, with the support of the first-years, pending the Eco vehicle race that takes place on Friday 16 February 2018 from 13:00. The ACT office is working towards obtaining sponsors for the overall winners of the race. Their aim is to give the college that wins the race a-once-in-a-lifetime opportunity to attend an official international car race, where they will be represented by their residence committees. The following race criteria apply: 

Race criteria:

Drag race

Fastest time taken to cover distance wins

Slalom race

Fastest time taken to complete course minus penalties

Obstacle course

Fastest time taken to complete course wins (Obstacles will be introduced on the day, no preparation)

Three lap-race

No winner, just preparation for final endurance race but drivers must change each lap

Endurance race

Longest distance covered

 

Students will also be working on art projects in the form of a canvas that must be made of waste materials such as plastic, scrap metal and/or sustainable organic materials. The work must be between three and five metres high and two to four metres wide. It should be durable and not perish if it is placed outdoors for a year. It must be accompanied by a manifesto that explains the theme and symbolism of the artwork so that the five colleges can effectively illustrate what is important to them and their community.

First-year students have also been assigned to participate in projects that engage with local secondary schools in the Bloemfontein area. The content of the projects will be directed through a short learning programme that will take place during the course of the year.

The Kovsie ACT team looks forward to the activities at the Rag Farm, and encourages students to attend and take part in their numbers. For more information about Kovsie ACT visit the UFS Rag page or the Ofm official website.

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.
