Brent Jammer, Lecturer in the Department of Agricultural Economics

The University of the Free State (UFS) is celebrating Youth Month by showcasing the positive influence of the institution on career development. As part of this initiative, we are sharing the stories of UFS alumni who are now working at the university.

Brent Jammer, Lecturer in the Department of Agricultural Economics, shares his UFS journey:

Q: Year of graduation from the UFS:

A: 2017, 2018, 2019

Q: Qualification obtained from the UFS:
A: I obtained my undergraduate degree in Agricultural Management with distinction in 2017 and received the ABSA award for best Bachelor of Agriculture final-year student at the faculty awards. In 2018, I obtained my honours degree in Agricultural Management with distinction and received the Standard Bank award for best BAgric Management honours student at the faculty awards. In 2019, I obtained my master’s degree in Agricultural Management.

Q: Date of joining the UFS as a staff member:
A: I joined the university as a permanent staff member (Lecturer) in September 2022. 

Q: Initial job title and current job title:

A: After completing my studies, I went on to work as a production manager on a commercial farm where I managed approximately 1 500 sheep. I returned to the university in 2022 and was then appointed as a Lecturer in the Department of Agricultural Economics.

Q: How did the UFS prepare you for the professional world?

A: The UFS served as a great foundation where I built my expertise with the knowledge and skills that I gained while studying at the university. The biggest advantage of being a UFS graduate is my ability to adapt in any space outside my comfort zone, which in turn made me excel in my field. The UFS Faculty of Natural and Agricultural Science is indeed the front runner in producing excellent students who can make a difference in the agricultural industry.

Q: What are your thoughts on transitioning from a UFS alumnus to a staff member?

A: Transitioning from UFS alumnus to a staff member is still a dream come true for me, and it's actually funny that the people who taught me during undergraduate studies are now my colleagues. So, being among them and getting so much support is what makes me feel at home at the university.

Q: Any additional comments about your experience?
A: Additionally, I am also an emerging cattle farmer, where I implement all the skills I obtained from the university in practice. I farm with approximately 70 cattle where I employ youth members from my community as a means of ploughing back in order to reduce unemployment and enhancing livelihoods.

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.
