The Institute for Reconciliation and Social Justice IRSJ) has initiated a Social Justice Week at the University of the Free State (UFS), which started on Friday 12 April  until Wednesday 17 April 2019. 

Ten key events took place during the week. It ranged from dialogues, workshops, talk shows, debates, and interactive displays and events on issues of multilingualism and diversity, social innovation, engaged scholarship, the Fourth Industrial Revolution, gender sensitisation, sexual consent, sexual preparedness, universal access, disability, anti-discrimination, and security.

There was also a round-table discussion on 17 April 2019 with various UFS stakeholders on off-campus student security as well as an inter-institutional discussion on the same topic. The UFS Debating Society will take on the topic of the UFS Language Policy, while Olga Barends from the Free State Centre for Human Rights will host a dialogue on sexual consent.

The IRSJ has also designed and implemented SOJO-VATION: Social Innovation/ Social Change, which strives to create a foundational platform where ideas of social justice, innovation, and engaged scholarship at the UFS and in society can be hosted. SOJO-VATION partners with the Office for Student Leadership, Development, and Community Engagement.

The collaborating partners for the Social Justice Week includes various UFS stakeholders such as the Sasol library, the Gender and Sexual Equity Office, UFS Protection Services, the Free State Centre for Human Rights, the Student Representative Council (SRC), the Office for Student Leadership Development, Kovsie Innovation, GALA, the FFree State Centre for Human Rights, SRC Associations, the Office for Student Governance, Kovsie Innovate, Start-Up-Grind, EVC, EBL, Community Engagement, the Institutional Transformation Plan (ITP) Dialogues Office, Residence Dialogues, UFS Debating Society, Debate Afrika!, the Center for Universal Access and Disability Support (CUADS), and the Gateway Office.

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.
