It is not easy to discern the silver in the lining of the pandemic cloud that we have been living under over the past twelve months. I hazard to say that for those at the bottom of the socio-economic heap, those whose daily life is nothing but a gut-wrenching struggle to scrape together a semblance of a meal, talk of silver linings is foreign to their experience. The pandemic has shown just how low leaders can sink when elected public officials steal and redirect food parcels – meant for the poor and destitute – for their own personal consumption, for those close to them through family ties, through friendship and through political affiliation, or sell it for personal financial gain. The intended relief measures, designed to be non-partisan, are used instead to promote the socio-political divisions that already exist in the community. The unspoken mantra seems to be: If you look like me, if you think like me, if you believe like me, if you speak like me, if your political beliefs are like mine, only then can you expect me to do the public good for you and for your benefit that I have been elected to do, even though I get paid for carrying out this very important task. Talk of unity is rich in such an environment.

Nation-building
The devastating impact of the pandemic will be felt for quite some time. In the next twelve months we must, despite the enormous challenges ahead, re-imagine and craft a future of unity, where personal, political, ethnic, racial, gender, economic, and other differences will not stunt and sabotage efforts of socio-economic renewal. This Human Rights Month is a stark reminder for us to go back to our foundations as a South African nation. It is a time to press the reset button in the agenda of nation-building. Nation-building is not achieved through a fiat, a ‘let-it-be-so’ declaration. While taking the necessary steps to rebuild a battered economy, nation-building also entails making the necessary investments in social support to alleviate the impact of the pandemic on the most vulnerable in society, while also ensuring that the white-collared hyenas are kept at bay. The right to health care, food, water, and social security is enshrined in the Constitution.  

The future
Nation-building also entails making bold investments in education, taking care that as budgets are re-organised, re-prioritised and reduced, the education sector is not made a casualty of austerity measures. We must not falter to build our nation on a solid foundation of education, ensuring that we make the right investments and the required interventions in this very critical sector. There are components in the sector that are weak and glaringly under-resourced, such as early childhood development, as well as post-school technical and artisanal training. We need to strengthen these as part of building a firm foundation for our fledgling nation. This is a very important asurance for the future of our nation. Only an educated nation is best equipped to confront the challenges that lie ahead, such as those that the COVID-19 pandemic has thrust upon us. The right to education is enshrined in the Constitution.

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.
