The search for the 2019/2020 #KovsieCyberSta team has been an exciting one, with Anderson Mosia and Olebogeng Tlhong coming out tops to beat the competition.
Anderson, a second-year BA Languages student, didn’t let last year’s failure deter his efforts to enter again this year. 

“I am hoping to achieve a lot of things. My milestone would be to raise the bar high for the next stars; I've got a lot in store,” he says. 

He says he is passionate about spreading love, and he will use this new platform to express himself.

It has been first-time charm for first-year LLB student, Olebogeng. She says as soon as she saw the competition was open, she knew it was something that would fit her persona. 

“I am hoping to not only grow as an individual, but to leave my mark. The question that I asked myself before stepping into this role, was –what’s going to be different because you stepped in? I aspire to document and present events in the best way that I know, while being open to learning and, through my knowledge, inspire and teach others.”

The 19-year-old says she will use her passion for serving to express herself best over the next 12 months. 

“I believe that it is my duty to use the knowledge I have acquired/am to acquire in order to make somebody else’s life better. So essentially, I am a servant leader; I believe that there is enough room for everybody to succeed,” she adds.

As #KovsieCyberStas, the duo will cover events on and around campus, while filming and presenting short video clips to give fellow Kovsies some insight into these events across the UFS’s digital platforms.

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.
