MESSAGE FROM THE RECTOR AND VICE-CHANCELLOR: UPDATE ON DEVELOPMENTS AT THE UFS

I hope you are well, healthy, and safe. I have experienced an overwhelming sense of commitment from staff and students across the university to make a success of the 2020 academic year. Thank you for working together towards this common goal.

Currently, we have a significant number of students back on the campuses in line with the university’s reintegration plan, and others are continuing with online learning. On 16 September 2020, President Cyril Ramaphosa announced that the country will move to alert Level 1 as from midnight on Sunday 20 September 2020. During Level 1 of the national lockdown, we will continue to return staff and students in a structured and phased approach according to the university’s reintegration plan. However, we are still unable to return all our students to the campuses, as we have to adhere to physical distancing and hygiene measures and also have to take into account the capacity of the lecture venues on the campuses, but most specifically the residences.

Please note that you will be informed by your faculty if you are required to return to campus during Level 1. If you have NOT been contacted, you will be supported through remote multimodal teaching, learning, and assessment until you are informed by your faculty that you can return to campus.

Data shows that most of you have adapted well to the blended learning modes – I find it admirable and inspiring. Rest assured that your lecturers are continuing to work hard to deliver a quality teaching and learning experience. Please use the #LearnOn material as a guide to plan for the second semester and engage with your lecturers on academic problems or consult with your faculty structures to find suitable solutions.

The university is aware that international students who have been residing outside of the country during Levels 5 and 4, may return to campus during Level 1; we will communicate with these students in due course.

I am confident that you are focused and committed to completing the second semester. We have prepared a safe environment for students who are returning to campus during Level 1. Sufficient hygiene measures are in place, as well as re-configurations to ensure physical distancing. The wearing of masks, physical distancing, and hand sanitising remain compulsory on all the campuses.

During Level 1, campus access will remain restricted – only those with campus access permits will be allowed to enter. Space in our residences remains limited due to physical distancing and residence students must comply with the protocols in their respective residences. See the Return to campus of students_Level 1 of national lockdown document for more information.

Although our country will be on Level 1 of the national lockdown, it is still extremely important that you remain vigilant and take ownership of your health and look out for the health of those around you. Ultimately, your health is your responsibility. Please do not let your guard down and adhere to the protocols and regulations – for your own safety, and for the safety of others.

It is also important to keep your mental health in check – make use of the #WellbeingWarriors campaign from our Department of Student Counselling and Development, which is aimed at encouraging health and well-being among students. Visit the COVID-19 website for comprehensive information and updates.

Although the infection rate in our country is decreasing, remember that the COVID-19 pandemic is still testing every aspect of society; we must not underestimate the impact that the pandemic still has on local and global communities. Take care of yourselves and those around you and comply with the national guidelines and regulations.

I wish you all the best with your studies.

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.
