The University of the Free State (UFS) invites you to the 2021 Virtual Graduation, where students who completed their qualifications in June/July of 2020 will receive their qualifications during the ceremonies taking place from 22 to 24 February 2021.

Bachelor degrees (435), higher certificates (86), advanced certificates (230), postgraduate certificates (4), national professional diplomas (203), advanced diplomas (13), postgraduate diplomas (158), bachelors honours degrees (22), master’s (201), and doctoral qualifications (70) will be awarded to students across the UFS Bloemfontein and Qwaqwa Campuses. 

Graduates in the faculties of Economic and Management Sciences, Education, Health Sciences, the Humanities, Law, Natural and Agricultural Sciences, and Theology and Religion will be honoured during the upcoming ceremonies for their academic excellence.

Graduation is the highlight on the university calendar, and even though this prestigious occasion will not be taking place traditionally, the UFS would still like to acknowledge and commemorate our graduates’ prestigious accomplishments. 

The COVID-19 pandemic has caused immense disruption in many aspects of our lives. Higher education institutions throughout the world were not exempt from the effects of the deadly virus. This has subsequently impacted the presentation of graduation ceremonies throughout the sector.
The UFS looks forward to virtually celebrating the milestones of all graduates at the virtual graduation ceremonies, and thus implores all graduates to join us in doing so. 

See information further below for details on how to join in on the celebrations.

The university hopes to celebrate many more graduations in future, but for now, the health and safety of our community is our primary concern.

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.
