Students urged to help combat crime
What to do in case of an attack? The UFS taekwondo team taught students a trick or two.
Speaking at the official opening of Safety Week, newly elected Student Representative Council (SRC) president of the Bloemfontein Campus called for students to come to the party in the fight against crime. “We encourage students to participate because it cannot just be the SRC, university management, and the police. Students need to join the Community Police Forum because these platforms are there for us to engage in. You must not die in silence, if there is a problem, raise it,” said Sonwabile Dwaba.

The University of the Free State’s (UFS) Protection Services in collaboration with the university’s BSafe campaign hosted the Safety Week from 3-6 September 2018 on the Bloemfontein and South campuses with the objective of keeping students and staff members informed on the measures in place, addressing pressing safety-related concerns, brainstorm ideas on how to beef up security, and distributing safety souvenirs.

Collaborative efforts encouraged

Brigadier Maehlo Lento, reporting on behalf of the South African Police Service (SAPS) Provincial Commissioner, said: “Robbery incidents have subsided but we still need to make sure that we continue and collaborate with students and all other roleplayers to make sure that we sustain the safety.”

The collective participation sentiment was also reflected by Prof Prakash Naidoo, Vice-Rector: Operations. “We are hoping through our annual Safety Week to reiterate our commitment to the safety of students, as well as bringing all roleplayers together to reflect on areas of cooperation and collaboration in an effort to improve the safety of student.”

Not just physical safety

Issues of mental health were discussed by the Next Chapter student organisation, while Embrace a Sister student organisation spoke about femicide and the safety of women. The scourge of gender-based violence formed the focal point of the Gender and Sexual Equity office’s address. In addition the Student Counselling and Development division offered invaluable advice on where those who exhibit symptoms of depression can seek help.

Other stakeholders who contributed to the success of this year’s Safety Week were the Mangaung Metropolitan Municipality, Department of Police, Roads and Transport, as well as Sector 3 Community Police Forum.

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.
