WomenOfKovsies Arina Engelbrecht advocates healthy living nationally
Arina Engelbrecht’s vision is for all Kovsies to lead holistically healthy lives.

How do you start living a healthy lifestyle? Arina Engelbrecht, a wellness specialist in the Employee Wellness Division at the University of the Free State (UFS) says it only takes a few changes. Her passion is to motivate people to live a balanced life.  

Being active enables a person to live life to the full. “Aim to exercise 150 minutes a week, which equates to 30 minutes five times a week in order to experience health benefits like prevention of lifestyle illnesses, better sleeping patterns, decreasing stress or anxiety and feeling more energetic,” says Engelbrecht.

Some of the initiatives Engelbrecht and her team drive are the Healthy Lifestyle Challenge, Park Runs in Bloemfontein, and the Healthy4Life Pedometer Challenge, which encourage staff members to become more physically active. “Everything we do, think or feel is influenced by what we eat! It is therefore important to eat a balanced diet. Healthy food = quality fuel = good health = sustained energy = peak performance,” she explains. 
 
Pedometer Challenge

In the space of eight weeks 240 staff members from all campuses walked 54 000km as part of the Pedometer Challenge. Engelbrecht and her team mobilised 53 active teams from all three campuses. Three of these teams emerged as the winners as they exceeded the target of 1 300km which is the equivalent of walking to Cape Town. In September 2018 the Challenge is going national as the North-West University competes against UFS.

Celebrating women

This Women’s Month Engelbrecht’s message to women of Kovsies is: “We must start embracing who we are and start believing in ourselves, whether it is in the workplace, in business, or at home.”

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.
