With the University of the Free State (UFS) academic programme suspended and following guidelines by the UFS Coronavirus (COVID-19/SARS-CoV-2) Task Team to minimise the gathering of people in one place, all UFS libraries will be closed from Friday 20 March to Monday 13 April 2020.

During this time, staff and students will not have any access to the following campus and branch libraries of the UFS Library and Information Services:

•    Sasol Library (Bloemfontein Campus)
•    Neville Alexander Library (South Campus)
•    TK Mopeli Library (Qwaqwa Campus)
•    Frik Scott Medical Library (Bloemfontein Campus)
•    Music Library (Bloemfontein Campus)

The university community is advised as follows:

•    Use Wednesday (18 March) and Thursday (19 March) to borrow books you might need during the long recess. During these two days, students are advised to take precautionary measures and avoid sitting in groups that might compromise their health.
•    During this time, all due dates for borrowed material will be automatically extended, no late fines will be charged, and patrons can return material when libraries reopen.
•    Please make use of the ‘Ask-a-Librarian’ service for any assistance you might require (go to the UFS Library and Information Services website – click Library Services – click Ask-a-Librarian); OR use the UFS Library social media.
•    The UFS Library and Information Services will also be available on a new ‘LiveChat’ service accessible here (listed under Resources – LibGuides). With this service, you can connect ‘live’ with your information librarian.
•    All planned activities for the South African Library Week are postponed until further notice.

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.
