Stagedoor Finals
Houses Vergeet-My-Nie and NJ van der Merwe won over the judges at the 2019 Stagedoor finals.

‘Vergeet van der Merwe’, a hybrid of female residences Vergeet-my-Nie and NJ van der Merwe, are the 2019 Stagedoor competition’s overall winners. The dynamic girl duo showed up and showed off during the 2019 Stagedoor finals in the Kopanong Auditorium on the UFS Bloemfontein Campus over the weekend.

The girls enthused the audience with a soul-filled sing-off and a relatable theatrical performance, which earned them both the audience’s and the judge’s best votes. Teams Welwitschia and Imperium (Welperium), and Outeniqua and Soetdoring (Outdoring), walked away with the second and third positions respectively, as each of the residences were recognised for team excellence and spirit when it came to creativity and overall acting in each of their performances.

The UFS Stagedoor competition is an annual event that employs first-years to take cognisance of the day-to-day societal issues and pressures that university students are faced with. In 2019, the event was for the first time entirely organised and ran by students for students.

The competition has over the years become a major highlight on UFS students’ arts and culture calendar and continues to be a platform of expression for residence and off-campus first-year students. Stagedoor performances are traditionally themed to tackle modern-day issues such as infrastructure and economic inequality, land reform, and education. However, this year’s competition engaged students in telling their stories without any restrictions, and still being able to effectively examine the pressures that come with varsity life, and many other issues that face South Africa, but more specifically the youth. The 2019 Stagedoor event was successfully coordinated and structured by UFS Bloemfontein Campus SRC: Arts and Culture, Patrick Chirilele, with help from Residence Committee (RC) Culture members.

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.
