Nosethu Badlezana, Academic Facilitator: Centre for Teaching and Learning

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.

Nosethu Badlezana shares her UFS journey:

Q: Year of graduation from the UFS: 
A: I completed my undergraduate degree in 2015 and thereafter obtained my honours in 2016.

Q: Qualification obtained from the UFS: 
A: The first degree I obtained was a BA in Communication with specialisation in Media Studies and Journalism. I then made the decision to pursue my honours degree in the same field.

Q: Date of joining the UFS as a staff member: 
A: In 2016, I began my internship on the Qwaqwa Campus with the Centre for Teaching and Learning’s former Curriculum Delivery and Innovation Division, which is now known as the Blended Learning Innovation Support and Services Division. The following year, upon completion of my internship, I was appointed as an Assistant Officer in the Academic Language and Literacy Development Division within the same department. Then, in 2022, I was promoted to the role of Academic Facilitator.

Q: How did the UFS prepare you for the professional world?
A: During my time as a student at the UFS, I followed a comprehensive curriculum that equipped me with essential skills to thrive in a professional setting. Through a diverse range of modules, I developed proficiencies in crucial areas, including time management, effective communication, problem-solving, critical thinking, self-management, and collaborative teamwork.

Q: What are your thoughts on transitioning from a UFS alumnus to a staff member? 
A: It's a fascinating journey, one that feels like a way of giving back to the community that nurtured and shaped me. Assisting students to achieve success in higher education doesn't feel like a burden to me, as I once walked the same path as a student at this institution. The UFS has provided me with a valuable network of support and mentorship, which has been instrumental in fostering a sense of security and confidence in my chosen career path.

UFS venture cleans up acid mine drainage

The system that puts oxygen back into the water.

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.
