Learners enjoy a lesson delivered through an All-in-One device at an IBP-served school.
“Everyone is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.” Eugene van Wyk, Project Coordinator of the Internet Broadcast Project (IBP) at the South Campus of the UFS, preaches a gospel along similar lines, a motto that belongs solely to the IBP: Taking quality education to where it matters.

Quality education accessible to all

Van Wyk believes that quality education should be accessible to all, especially as a tool to relieve poverty in disadvantaged communities. That is why he has made it his aim to extend the reach and exposure of the IBP. To that end, the IBP partnered with the Free State Department of Education (FSDoE) in presenting open days during August and September 2018 in each of the five Free State districts, emphasising innovation in education. At each of these days, the IBP presented their methods and successes, highlighting their use of innovation and technology in not only school education, but teacher development and upliftment as well.

Building on existing technology

The IBP lives up to its motto by building on existing technology, while thinking up new ways to use what is available. In addition, the IBP makes innovative use of emerging and new technologies. For instance, Van Wyk often quotes from a presentation by Ray Kurzweil, director of engineering at Google, author, and futurist, at the 2009 Handheld Learning conference: “Mobile phones are misnamed. They should be called gateways to human knowledge.” Therefore, plans are under way to develop a mobile app that will allow learners to download lesson content and even share it with learners who do not attend a Free State secondary school served by the IBP.

The value of the IBP can be seen in the tremendous upturn in matriculation success rates in the province, an impact that Van Wyk and the E-learning division at the FSDoE are keen to maintain and spread.

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.
