Thulaganyo Molebalwa recently graduated and is looking forward to entering the workforce and learning from the best in the different industries.
My name is Thulaganyo Molebalwa. I recently graduated with my bachelor’s degree in Governance and Political Transformation from the University of the Free State (UFS), and I am currently job hunting. I am looking forward to entering the workspace and developing as an individual while learning from the best in the different industries that I will hopefully become exposed to. 

When I reflect on my varsity career, I cannot help but remember the beginning of the second semester of 2018. I thought that I had one more semester left at the UFS, but then later found out that I still had a full academic year ahead of me in 2019. Learning this news nearly broke me; I was told that I still had a few outstanding modules to complete, and that I did not have enough credits to graduate. 

This was the beginning of a downward slope that left me in a very dark place in my life. At the time, it felt like everything was working against me, and it didn’t help that all my peers were graduating and progressing while I felt stuck. I developed a very negative mindset and slept a lot in an attempt to cope with my stress; I avoided people/public spaces because I just wanted to be alone. 

I started confiding in my family and friends about how I felt, and how everything had taken a heavy toll on my mental health and well-being. 

Look, it was not easy, but having someone to talk to has made a big difference and helped me get back to my normal daily routine, doing things I enjoyed. I even started a YouTube channel.

As students, we are often faced with different challenges. The university environment can become quite stressful for most people, because we are forced into vulnerability through our academics, methods of studying, and our social lives. 

I think it is important to prioritise your mental health at university by using resources such as the UFS Department of Student Counselling and Development to learn and be more aware of issues around mental health. I believe this would help a lot of students to realise that they are not alone and that there is help available.

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.
