With the most gruelling year recorded in our entire lives, gradually coming to an end we remain hopeful and thankful that we have made it through. From the unexpected shock of going into lockdown, to the worry of having to use a blended approach to succeed in your academics and now finally settling into a new normal, we at the advising office bestow upon you the title of Kovsie champion…because that's exactly what you are!

One of our many champions, Carli Kleynhans, a 3rd (final) year student enrolled for BA Psychology and English shares how she survived…no, actually how she has thrived in 2020. 

• What was your biggest concern about your academics when you found out the country was going into lockdown?

My biggest concern about my academics as a final year student was whether the online learning and tests would provide the same in depth learning experiences that are necessary to build upon for future studies.

• What are some of the challenges you've experienced along the way?

Staying focused and trying not to procrastinate was a big challenge I had to conquer, especially trying to not be distracted by my family and my phone. How I survived and was able to thrive in 2020!

• What are some of the strategies you've used to ensure your academics don’t suffer? 

Time management was one of the most important strategies that I applied. For most of my classes, I was able to focus each week on a different module, by working and studying in advance I was able to keep up with my workload and still have the weekends to focus on myself, therefore creating designated time to work, study and also time to relax and read. 

• What support have you received from the institution that's helped you thus far? 
Most of my lecturers have provided needed support regarding our academics. The institution helped provide clarity with everything that was going on. 

• What do you think the UFS could have done differently to support student success? 
I think the UFS could have provided more resources for the final year students, especially considering we have to apply for further studies; online it was difficult to discern exactly what was necessary for the applications, whereas in class I feel more information would have been provided. 

• What has kept you motivated? 

Knowing it is my final year has helped to motivate me, as I have to use these grades to apply for further studies. I recently received recognition from Golden Key and this helped to further inspire me to work even harder at my academics.

• What advice do you have for your fellow Kovsies who are finding it difficult to keep going? 
Remember to make time for yourself, to look after yourself and your mental health, especially in these difficult times. Work in advance and keep to your personal academic calendar.

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.
