Communities are beginning to wonder if universities exist for themselves or for their communities. This is the view shared by Prof Pearl Sithole, Campus Vice-Principal: Academic and Research, during the opening of the two-day Travelling Seminar that was recently hosted on the Qwaqwa Campus. 

Research in communities

“This event is well-placed, considering what many communities are currently going through. We must ask ourselves what we are doing with and for our communities. We must be careful to not only reap data from them, but to be scientific in a way that accommodates our communities and allows the African and indigenous agenda into the world of science,” she added.

Providing background to the concept of homestays, the Director: Institute for Rural Development at the University of Venda, Prof Joseph Francis, acknowledged the role played by communities in research.

 “This seminar seeks to develop a testable framework for homestays; a concept enabling postgraduate students to be placed with rural families while conducting research in the area. It is also aimed at giving birth to a vibrant, community-based rural and regional development network connecting grassroots communities, business, government, and non-governmental stakeholders,” he said.

“We do not only train students for local deployment and within national borders. It is important to produce an ‘all-weather’ graduate who stands out wherever they are. Graduates must ask themselves, ‘what in me stands out among the rest?’ As a student and researcher, never see yourself as being confined to the space where you are,” he added.

Students as ambassadors

Cornelius Hagenmeier, Director: Office of International Affairs at the University of the Free State, said for internationalisation to work, it has to be inclusive and create student ambassadors. “As this seminar will show, our networks of stakeholder communities go beyond the national confines and borders. We must strive, through this project, to create ambassadors of the university, of communities, of the broader South Africa and Africa,” he said.

Participants in the seminar were academics and postgraduate students from both the Universities of the Free State and Venda. Also present were community and traditional leaders from Qwaqwa and the Vhembe District in Limpopo.

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.
