Mokitlane Manyarela reflects on his 41-year journey with the UFS Qwaqwa Campus

He has seen the many changing faces of the Qwaqwa Campus, and four decades later, Mokitlane Manyarela says he would not have it any other way.

Fondly known on campus as ‘Ntate Manyarela’, he has been with the campus for 41 years, having started on 1 January 1982 at the ripe age of 18 years. Manyarela recently received a long-service award for 36 years of service, dating back to when the campus moved to its current location from where it started at Lere la Tshepe in 1982.

He recalls arriving at the campus offices in town in 1982 seeking employment, as there were no “buildings or campus” back then.

“I started working as a general worker because there was nothing else to do. All the university’s content would come from Turfloop in those days. As time went by, I worked in the reprographic section, printing exam papers. That was my first official job until the campus moved in 1988 to where we’re now located. All the buildings that are now filling this campus were constructed right in front of my eyes,” he said.

He went on to work for various departments on the campus, such as procurement, cashiers, and finance. In 2007, he joined the transport department, and that is where he is still working as an assistant officer. “What’s made me stay this long is not getting into fights with anyone and always following instructions given to me. I’ve worked under many different bosses, and I believe that none of them have anything negative to say about me. Therefore, I can say I’ve never had a reason to leave because everything I’ve done, I have done wholeheartedly.”

Manyarela said the university also afforded his wife and children the opportunity to obtain their degrees, which is something he considers a huge achievement. “All that I have has been achieved at this institution. It’s been a wonderful journey. I have no complaints, and I am content. I’ve reached my old age here. I don’t know any other job or work environment; this place has become like home to me, and I’m prepared to still give my all to this university, even though old age is now catching up with me.”

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.
