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.

Dr Nokuthula Tlalajoe-Mokhatla, Academic Head and Senior Lecturer at the Division of Student Learning and Development, shares her UFS journey:

Q: Year of graduation from the UFS:

A: I graduated in 2010, 2011, 2013, and 2021 (virtual graduation).

Q: Qualification obtained from the UFS:
A: BSc Biochemistry and Microbiology, BSc Honours Biochemistry, MSc Biochemistry (Cum Laude), PhD in Health Professions Education

Q: Date of joining the UFS as a staff member:
A: I joined as an official staff member on 18 January 2016; however, I have been in the HR system since my third year (2009) when I was appointed as a Laboratory Assistant.

Q: Initial job title and current job title:

A: In the context of point 3, I would safely say I moved from Laboratory Assistant, to Demonstrator, to Lecturer, and now Academic Head of the division and Senior Lecturer.

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

A: Every human being can be taught a skill, be it a scientist, health professional, or accountant. However, how their soft skills complement or lack to complement the core knowledge and application will set that individual apart. That being said, I have utilised the vast opportunities that are always accessible to enhance one's development with regard to lifelong learning skills. My biggest gain was the Engaged Leadership Programme (middle management level), which I completed in 32 weeks and obtained a distinction. That type of training set me in a position that could easily have played a role in me being able to progress further in the professional world.

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

A: The outlook is so different when you are a staff member. I am enjoying the world of being a staff member more. This is due to my struggles as a student – a story for another day. The perks and benefits are more as a staff member, and your world gets bigger and bigger. Networking with like-minded people and contributing to day-to-day activities is mind-blowing for me.

Q: Any additional comments about your experience?
A: I appreciate the support systems in our setting; it comes in handy when we doubt ourselves and think we are not enough or adequate. What I do appreciate is the opportunities that are accessible, and with the help we have in place, it brings a sense of ease to know you can equally access it.

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.
