The Council of the University of the Free State (UFS) approved the lifting of the institution’s COVID-19 Regulations and Required Vaccination Policy with immediate effect.

“Since the declaration by the Government on 22 June 2022 that the COVID-19 regulations will be repealed, the UFS has conducted a risk assessment to determine the risk of exposure to staff and students. From the assessment, it was clear that the university’s COVID-19 infections are currently a low risk,” said Prof Francis Petersen, Rector and Vice-Chancellor of the UFS.

Factors that contributed to this low risk include the following:

  • No COVID-19 positive cases among UFS staff and students have been reported in the past month.
  • The high number of vaccinations among UFS stakeholders. In addition, the current national immunity level of the total South African population is high.
  • Certain faculties and postgraduate students are currently proceeding with hybrid/online learning, which minimises the risk of possible COVID-19 infections on the university’s three campuses.
  • In its correspondence of 23 June 2022, the UFS urged all staff and students to continue wearing masks should they have comorbidities and/or symptoms of illness, thus safeguarding other stakeholders.

“We believe that COVID-19 no longer poses an immediate threat to the safety of our staff and students, and that the pandemic is at a stage where they should take responsibility for their own safety. This can be mainly ascribed to the success of the implementation of the policy. Staff and students who still wish to wear masks are urged to do so at their own discretion. Those who have not yet been vaccinated against the virus and have no

known condition preventing them from doing so, are advised to get vaccinated for their own safety and protection,” said Prof Petersen.

The UFS COVID-19 Regulations and Required Vaccination Policy was approved by the University Council on 26 November 2021 and implemented on 6 December 2021. The university commenced restricting unvaccinated individuals from accessing its campuses as of 14 February 2022.

“If the national regulatory environment with respect to COVID-19 is changing to such an extent that the policy needs to be re-implemented, the university’s executive management will act accordingly, and hence the COVID-19 Regulations and Required Vaccination Policy remains a policy of the university as approved by the UFS Council on 26 November 2021.” said Prof Petersen.

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.
