International student symposium
Seithati Ramonaheng at the International Students Policy Review Symposium, where she contributed to discussions on policy alignment and student experiences.

Seithati Ramonaheng, who supports International Students Administration, Immigration, and Medical Aid in the University of the Free State (UFS) Office for International Affairs, was recently invited to attend the International Students Policy Review Symposium hosted by the Vaal University of Technology.

 

A platform for change

According to Ramonaheng, the symposium was more than just a platform for discussion; it was a catalyst for change in how South African universities and policy makers address the challenges and opportunities of international education. “By engaging diverse stakeholders and thoroughly reviewing both the legal and institutional frameworks, the symposium aimed to contribute significantly to the creation of inclusive, accessible, and supportive environments for international students in South Africa,” she said. During the event, she also presented on the inconsistencies between the Immigration Act and the practices. 

In her presentation, Ramonaheng shared findings from data collected across various institutions, which closely aligned with the experiences of international students at the symposium. These students highlighted the challenges they face when applying for study visas. Additionally, recommendations were put forward to help ease these difficulties.

She continued, saying that it was inspiring to connect with other professionals and gain new perspectives that she believes will be beneficial to their team in the UFS Office for International Affairs. The symposium brought together key voices in international education, including Advocate Sipho Mantula, a human rights lawyer from the Thabo Mbeki School at UNISA; Rudy Petersen, a strategic manager at UJ; and Segomotso Phetlhu, managing director of the International Students African Union (ISAU). Student leaders from the University of Venda, UJ, and Sefako Makgatho Health Sciences University also participated in the discussions.

 

Improving the student experience

International students from Nigeria, the Democratic Republic of Congo, Kenya, Zimbabwe, South Africa, Eswatini, and Lesotho shared their experiences and proposed ways for higher education institutions and the Department of Home Affairs to improve the international student experience.

Ramonaheng found the symposium to be a valuable experience that allowed her to get a deeper understanding of international students’ experiences as a whole. She looks forward to applying her insights within the UFS Office for International Affairs to further support international students. She will also contribute to the scholarship of internationalisation by publishing research that documents the immigration experiences of international students.

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.
