Solar charging stations ready for use
Students and staff will be able to enjoy the new social space equipped for studying or leisure activities.

Solar charging stations were recently launched on the Bloemfontein Campus. These units can be used by students to charge their phones, tablets, and iPads. Solar charging units will be installed on the University of the Free State’s BloemfonteinSouth, and Qwaqwa Campuses.

Social spaces make for happy faces

A new central social space where students can eat, socialise, study, and relax is one of several exciting developments that UFS students can look forward to on campus. The social space can be found in the open area between the Biology Building, Chemistry Building, and the West Block on the Bloemfontein Campus.*

“The space consists of concrete benches with roof coverings, paving, and electrical supply points fed by solar power for students to charge their cellphones or laptops,” says Maureen Khati, Assistant Director: Project Management, Facilities Planning.

Solar panels have already been installed on top of various buildings on all three campuses, for example, 1 280 solar panels on the roof of the Thakaneng Bridge on the Bloemfontein Campus. The computer laboratories and the projected Afromontane Research Centre on the Bloemfontein and Qwaqwa Campuses will be equipped with freestanding solar roof solutions.

The project was a collaborative effort between the UFS and FCE Consulting Engineers. Coenie van der Merwe, Prototype Design Engineer, played a vital role in designing the charging unit.

Project to enhance sustainability and address student needs


Prof Nicky Morgan, former Vice-Rector: Operations, says, “This should be a symbol of affordable opportunities that will both save the planet and enhance financial sustainability.” Nico van Rensburg, Senior Director of University Estates, says, “This renewable energy project is an innovative way of addressing student needs.”

However, students are advised not to charge other electrical appliances besides their phones and iPads at the charging stations, as this may cause the charging unit to trip.

The UFS was recently awarded for its contribution towards sustainability. This was in recognition of its amazing initiative to install and operate photovoltaic (PV) and greywater systems on all three of its campuses.

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.
