University of Limpopo visits UFS Protection Services
Staff from the University of the Free State Department of Protection Services pictured with the delegation from the University of Limpopo during their benchmarking visit.

The University of the Free State Department of Protection Services hosted a delegation from the University of Limpopo on Friday, 13 May 2022 as part of benchmarking best protection service practices. 

During the visit, discussions included the management of student protests, gender-based violence, fire emergency responses, and challenges experienced with the Campus Protection Society of Southern Africa.

The visit by the University of Limpopo follows similar benchmark visits by the Central University of Technology, Sol Plaatje University, and the University of Johannesburg.

Noko Masalesa, Senior Director: Protection Services, said: “The visit by the University of Limpopo was used to take them through our vision 2024, to show them some of the advanced CCTV cameras that the UFS has installed, the policies, and organisational structure. Part of that strategy is to enhance the university’s security technology in line with the best practices.”

Masalesa said: “The UFS has a good model to manage all the different functional areas of the Department of Protection Services, and most universities are impressed with the new CCTV cameras that we rolled out and the other advances made in the development of protection services over the past five years.”

To remain among the leaders in protection services within the higher education, the department also visited Stellenbosch University, the University of Cape Town, Cape Peninsula University of Technology, and the University of Nairobi and Kenyatta University – both in Kenya.

Mampuru Mampa, Director: Safety and Security at the University of Limpopo, said: “Like other institutions, the University of Limpopo is dealing with crimes affecting students on and off campus, as well as student protests. Fostering collaboration and benchmarking will assist our protection service departments to develop and implement a standardised approach to improve safety on our campuses.”

On lessons learnt during the benchmarking tour, Mampa said: “We have learnt about security system integration, investigation systems approach, off-campus security, and student protest management.”

Mampa believes “it is important for protection service departments across the higher education sector to develop standardised security measures to improve safety, and benchmarking assists in closing gaps in protection services”.

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.
