Add these emergency safety contacts to your speed dial.
Staying safe during the coronavirus pandemic extends to ensuring that students at the University of the Free State (UFS) are safe from crime. Crime in South Africa remains an unfortunate reality which continues to affect students, staff and the institution in general. 

“Crime requires constant vigilance from the community and this can only be achieved through initiatives that are aimed at informing the community on what to do and what not to do. To this end the BSafe Safety First flyer is geared at informing specifically the student community on safety measures that must be taken,” said Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison at Protection Services.

The Safety First flyer is a guide for students to be crime-conscious whether at their accommodation, on the street, or in their vehicles. It also offers tips on how to act responsibly as far as alcohol and drugs are concerned.

Engaging students on their safety 

UFS Protection Services recently engaged with off-campus residence students in Bloemfontein in order to provide tips on how to stay safe in their neighbourhoods. During the engagement, the new Safety First pamphlets were distributed, and students were encouraged to join the Student Crime-Stop Brandwag WhatsApp group.

As from 15 June 2020, Nissi Armed Response was deployed from 18:00 to 06:00. This initiative has already led to them responding to several suspicious persons and vehicles, as well as some minor incidents and disturbances. Two arrests were made on different occasions as a result of the deployment. In the first incident, a suspect was arrested on 27 June 2020 after a burglary in Brandwag, and the second relates to a suspect who was arrested on 10 July 2020 after threatening students at Universitas.

These successes were the result of student and community participation in providing information, coupled with excellent response from private security companies, including Nissi Armed Response, VR Security, and BloemSec.

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.
