Muhammad Cassim, a second-year student in the Department of Engineering Sciences in the Faculty of Natural and Agricultural Sciences at the University of the Free State, will participate in the winter university project in Pskov, Russia, from 25 November to 9 December 2024.

The winter school aims to strengthen relationships among young engineers and deepen international interaction via skills improvement, joint projects, and social cohesion. The programme boasts a densely packed education block, project block, and cultural block.

Cassim is part of the UFS Grid Related Research Group and actively participates in research centred on complexity science. He intends to complete his BSc Physics degree with Engineering subjects and progress towards postgraduate studies in the UFS Department of Physics.

He is currently working on verifying experimental developments in the field of synchronisation in complex networks. While he has already completed this high-performance computing training in his first year under the leadership of Albert van Eck (Director, UFS E-research), he is looking forward to the masterclasses in holographic modelling, deep learning, direct laser deposition, and database. Closely resembling his current research, he will have the opportunity to gain more experience in the use of set theory and graph theory in solving digital information processing problems.

For more information about international scholarships for study abroad opportunities, contact Mbali Moiketsi in the Office for International Affairs.

Cassim’s student profile is the culmination of the department’s strategy to produce young applied scientists who are subjected to the culture of research during their undergraduate study and could articulate with ease to other departments for postgraduate studies.  The department aims to align with the UFS’ Vision 130 by producing competitive students who can operate in the postgraduate paradigm with the digital themes of veterinary science and ecological engineering science.

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.
