Social work

South Africa celebrated Human Rights Day and World Social Work Day on 21 March 2023. Social work is a profession that advocates for the human rights of people as well as focuses on the responsibility that comes with these rights. Just as the Bill of Rights is the cornerstone of democracy and protects our rights, the social work code of ethics is the cornerstone that ensures quality social work services. 

The University of the Free State (UFS) second-year social work students took an oath on 22 March which binds them to the social work code of ethics. Social workers have the Global Agenda for Social Work and Social Development which consists of four pillars. Focus is drawn to the last pillar, Strengthening Recognition of the Importance of Human Relationships. Human relationships are the core of social work and social development. These relationships take various forms, including social, personal, interpersonal, and therapeutic relationships, among various people and in various settings. In relationships where people flourish, trust is crucial. In contrast, mistrust skews relationships in a negative way. 

Respecting diversity through joint social action

The Ubuntu pan-African philosophical framework is the greatest place to understand the significance of human relationships. To promote and strive for the strengthening of relationships, this year’s theme for Social Work Day is “Respecting Diversity Through Joint Social Action”. If we can stop criticising people that do not live, believe, or think according to our constructed standards of being, we will be able to do so much more as humanity. If we start embracing peoples’ diversities and take time to start building relationships with various people and bridge any existing gaps, we will realise that diversity is an integral aspect of changing the world in a positive manner. Corresponding to human rights and the theme of World Social Work Day, is the theme “Destigmatising intellectual disability through shifting attitudes” for Intellectual Disability Awareness Month [IDAM] which also takes place later in March. Another way through which we can start building relationships and embrace diversity is by participating in this year’s South African Federation for Mental Health challenge where CEOs of different institutions are challenged to spend one day in a wheelchair as part of an awareness-raising campaign to destigmatise intellectual disabilities.

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.
