Kovsie Health nurses
The University of the Free State has nursing staff on the Bloemfontein, South and Qwaqwa campuses who serve staff and students daily.

Being able to care, love and help others. These are some of the reasons why nursing staff from Kovsie Health at the University of the Free State (UFS) enjoy and get fulfilment from their profession.

They believe in making a difference and live it out daily while at work on campuses of the UFS.

Like many in their field, they overcome challenges to assist others and that is why Kovsie Health also celebrates International Nurses Day today.

International Nurses Day is celebrated on 12 May to honour nurses around the world for the work they do. It is celebrated on the day Florence Nightingale, the founder of modern nursing, was born.

According to Sister Riana Johnson, Deputy Director: Health and Wellness Centre at the UFS, it is important to celebrate the day as it honours nurses, who often work under challenging circumstances.

Nurses from Kovsie Health serve students and personnel on the UFS Bloemfontein, South and Qwaqwa campuses.
Johnson says her love for people made her chose nursing as a job. “It is a profession where I can live that out by caring and helping others.”

Sister Florence Maleho, who works on the South Campus, agrees: “It is all about giving your best, forgetting about yourself and being there for others.”

According to Sister Corné Vorster her work is challenging on a cognitive level and fulfilling.

“It is a very stimulating and in the same sense you work multidisciplinary with many other disciplines in the medical field.”

Sister Sarien de Necker says helping students in need and seeing their grateful response makes it more than worthwhile. 

“It is about really making a difference,” she says.

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.
