Karee and Tswelopele win Stagedoor finals 2018
Karee and Tswelopele joined forces to win Stagedoor 2018.
Triumph in categories for best creativity, best drama, and overall performance, were the order of the night for the dynamic-duo, Karee and Tswelopele. Their heated performance stole the judges’ hearts and earned them their first-place victory. “Beylief”, the words Beyers Naude and Madelief joined together, won second place for the authentic story they told with their unique rendition of musical theatre. Armentum and Khayalami secured third place.

The Stagedoor finals marked yet another spectacular, spirit-filled night for first-year students and the Kovsie community. The Kopanong Auditorium stage lit up with theatrically performed stories that are relevant to South Africa’s modern society.

The Department of Arts and Culture established Stagedoor as an interactive theatre and musically infused cultural competition for the student residences and which is unique to the University of the Free State (UFS). 

The competition’s aim is to tackle modern-day issues such as infrastructure and economic inequality, land reform and education. It also aims to examine the pressures that come with university life, and many other issues that face South Africa, but more specifically the youth. First-year residence students are then tasked with the duty of transforming the “script” and bringing it to life.

This year’s Stagedoor of course encompassed heart-wrenching content that depicted resolute attitudes from students who not only wrote their own scripts, but who performed with spirit that was lit by fire. To view the videos that were taken on the night visit the UFS Twitter and Facebook pages.

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.
