EMS graduation
Jan Johannes van Niekerk and Pierré Ludwig Koekemoer

This year, two proud recipients of the Dean’s Medal were honoured during the 2020 UFS Virtual Graduation Ceremony. Jan Johannes van Niekerk received the award for the best results in respect of a Bachelor’s Degree in the Faculty of Economic and Management Sciences (Bachelor of Accounting), and Pierré Ludwig Koekemoer was awarded the medal for the student who achieved the best results in respect of a Bachelor Honours Degree in the Faculty of Economic and Management Sciences (Bachelor of Commerce Honours with specialisation in Marketing).

Prior to commencing his studies at the UFS, Van Niekerk attended Fichardt Park High School in Bloemfontein.  Van Niekerk describes his time thus far as a student in the School of Accountancy as “nothing less than special”.  He adds that “… the support from the lecturers is really great … every lecturer has always tried to help me to the best of their ability!”

His favourite subject is Financial Accounting, and his Financial Accounting lecturers inspired him to follow in their footsteps; accordingly, he became a Financial Accounting tutor in his second and third years of study.  “As academic staff, we have come to know Johan as a pleasant and well-mannered, diligent, and hardworking student who pays attention to detail,” says Prof Frans Prinsloo, Director: School of Accountancy.

Johan is completing his BAcc Honours studies this year and will commence his training contract with Enslins Auditors in 2021 to qualify as a chartered accountant (SA).

“Pierré Koekemoer is one of the most decent young men I’ve met in years.  Hardworking, diligent, and one of the most respectful and responsible people I know,” says Prof Brownhilder Neneh, Associate Professor in the Department of Business Management.

Pierre Koekemoer was identified as the Best Honours Student for 2019 in the School of Accountancy, as well as the student with the best Honours script.  Koekemoer excelled during his Honours year, and successfully managed his responsibilities as student assistant/marker; he was also part of the City Lodge Marketing project that took place during the second semester.  

The General Manager of the Fairview Hotel in Nairobi, Kenia, offered Koekemoer a short internship at the beginning of 2020, as he was impressed with his performance.  Koekemoer could not accept the job, as he had obtained permanent employment and did not want to lose the position. “This also speaks of his integrity, as he had already committed to the company,” comments Prof Neneh.

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.
