UFS and CUT joint SASUF Research Symposium discusses urbanisation

The University of the Free State (UFS) and the Central University of Technology (CUT) recently joined hands with the Swedish University Forum (SASUF). The universities jointly presented at a research seminar with the theme: ‘Urban Rural Dynamic’. The seminar was a side event to the stream ‘Urbanisation in the 21st Century’ of the SASUF Sweden-South Africa Research Week that took place in the same week. This stream of the research week was academically chaired by Wanda Verster from the UFS Department of Architecture. 

SASUF is a collaboration of 30 universities in Sweden and South Africa together with embassies, civil society organisations, funding agencies and ministries in both countries of which CUT and UFS are partners. Other themes of the research week were ‘Climate Change, Natural Resources and Sustainability’; ‘Transforming Higher Education Curricula’; ‘Social Transformation Through Change’; ‘Understanding the Burden of Disease’; and ‘Digital Technologies, Big Data and Cybersecurity’. One of SASUF’s main goals is to connect researchers with funding agencies, industry, ministries, and society in working towards the Sustainable Development Goals. 

Tri-partite between local and international universities
The first day of the event was hosted by the UFS Department of Architecture on the Bloemfontein Campus and was supported by the UFS Department of Urban and Regional Planning

The focus of the seminar was on the rural/urban dynamic that secondary cities are frequently experiencing.

Researchers from the UFS, CUT and Malmö University in Sweden presented at the seminar. Stuart-Denoon Stevens, an honours student from the Department of Urban and Regional Planning at the UFS, presented his research on human settlements. “There are 200 million informal settlements in Africa. In 1994 there were 260 informal settlements in South Africa. Today we have 2600 informal settlements,” said Stewart. 

Take hands, not handouts
He believes that one needs to support what is happening rather than introduce new technology all the time. “Take hands, not handouts,” he said. 

Presenters from the CUT included Dilip Das, who presented on sustainable urban roads and transport, as well as Oke Saheed, who gave an overview of research on sustainable water resources and environment. Prof Nils Ekelund, the head of the Department of Science, Environment and Society at Malmö University in Sweden, presented on perceptions of the ecosystem services concept. He presented together with his colleague, Per Schubert, a lecturer in physical geography. 

The Director: Internationalisation at the UFS, Cornelius Hagenmeier, stressed in his welcoming remark the contribution SASUF and the side event organised by UFS and CUT make toward comprehensive internationalisation and strengthening the local collaboration between the two universities in Bloemfontein.

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.
