KovsieFM programme manager joins SuperSport as field reporter
Sam Ludidi.

Sam Ludidi is no unfamiliar face on campus. He is currently busy with his second year of a BA Communication Science degree but started off as a BSocSc student five years ago. This KovsieFM programme manager recently joined the SuperSport team as a field reporter. He was selected from 70 candidates and recalls the phone call he received as the best he ever got. We checked in with him to see how he was enjoying the limelight.

It is difficult to choose between television and radio ... I think I prefer television. Then again, there’s a certain skill you need for radio because people don’t see you – that challenge intrigues me. But since I’m an expressive person, television allows me to express myself in full view of the audience.

Sport is my true passion, without a shadow of a doubt. I was born and raised in a sports-crazy house and always loved it – even watching the Proteas’ unfortunate loss to Australia in the Cricket World Cup when I was four. I’ve always loved cricket, but I just cannot keep myself away from rugby. Between the two sports, I’d probably lean towards rugby from an off-the-field perspective, and cricket if I’m on the field.

“You only have one chance
to make it work.”

The best and worst thing about being a television presenter is that it is live. You only have one chance to make it work. When I get it right, I feel great, but on a difficult day, I am hard on myself. I’m still somewhat new to television, but the trick is to find out what makes me different from the rest. My character and charisma make me stand out.

I still can’t believe ... that I am doing my dream job, and it almost came out of nowhere. My incredible support structure from since before my TV presenter job still sticks with me. I learnt from my mother to glorify God with the work that I do, I know that He’s opened many doors which led to this and I cannot express just how blessed I am.

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.
