Ghanaian contemporary artist, Ibrahim Mahama, visited the Department of Fine Arts at the University of the Free State (UFS) to share insights with staff and students during his stay in the country.

Dr Adelheid Von Maltitz, Senior Lecturer in the Department of Fine Arts at the UFS, highlighted the significance of Mahama’s visit which took place from 21 to 28 March 2024, marking the first instance of such interaction between a Fine Arts department in South Africa and Mahama. She remarked, “It is truly astounding that a person of his calibre dedicated time to focus on our department, and I believe this has catalysed a positive shift within our department.”

Mahama’s impactful presence at UFS

Dr Von Maltitz emphasised that Mahama’s visit aimed to offer staff and students a glimpse into his artistic process and mindset. During his time at the UFS, Mahama, who was virtually overseeing his latest recent large-scale artwork titled Purple Hibiscus, which involved wrapping the Barbican Centre in London, engaged extensively with staff and students from the department about their research. He shared insights into his creative journey, presented select works, and conducted critique sessions with fourth year and postgraduate students, among other activities. Dr Von Maltitz believes this interaction, particularly with students, has significantly bolstered their confidence as aspiring artists, preparing them for professional endeavours.

Broader implications and future prospects

Mahama’s visit not only energised the department’s academic environment but also holds broader implications. Dr Von Maltitz asserted that it will solidify the department’s identity nationally and create avenues for students to pursue residencies in countries like Ghana. Therefore, maintaining a fruitful relationship with Mahama remains a priority for the department.

Reflecting on the visit Dr Von Maltitz concluded, ‘’the key takeaway, especially for the students, was witnessing the potential of their works within the broader South African and international contexts. “

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.
