If all works out, Kovsie student Stephan Diedericks could change the face of the Mangaung Metropolitan Muncipality’s transportation facilities and save the city millions in maintenance costs while generating income.

The Masters Architecture graduate designed an innovative model titled An Interminable Living Machine: Humanizing and Re-appropriating the dormant Mangaung Intermodal Transport Facility (MITF) into a living, economic systems of change which won him the Corobrik Regional Student of the Year Award. The awards ceremony was hosted by the UFS Department of Architecture on 22 November 2019 at the Bloemfontein Campus.

A living machine

Re-appropriating the Bloemfontein taxi terminal located in the Central Business District (CBD) which has been non-operational for a few years would mean that the building sustained itself, and acted a power generator both environmentally and economically. 

Diedericks was inspired by the need to improve the quality of life for the people of City of Roses. “This course helped to broaden my perspective on the power of architecture and the social change that it can bring to people's lives,” he said.

An environmentally-friendly concept

According to the young architect, the facility would be water efficient. “Bloemspruit channels run underneath the proposed site and water will be filtered through biologically that will provide water to the entire site creating a self-sufficient living building with water at its heart.”

A thriving economic hub

Diedrick’s 220-page thesis details how the site of the intervention was once home to Bloemfontein’s first power station and that it is this concept of power generation that led him to place clients at the centre of the project as a catalyst for change.  

“The Small, Medium and Micro Enterprise Business (SMME) division of the Free State Department of Economic, Small Business Development, Tourism and Environmental Affairs (DESTEA) serves as the catalyst and a power generator that breaks open the solid mass of the MITF. Several subsystems, including aquaponics and SMME training, feed of the main catalyst and in turn provide resources in the form of food and business training to ground-floor users and micro-enterprise users onto latch onto over many decades of growth,” he explained.
 
A bright future ahead

"The only thing that we have and you don’t is experience,” said Petria Smit, a lecturer at the Department. “Some of your talent far exceeds ours.” During the awards ceremony, she said it was a privilege to work with students of such impressive calibre.

The awards, which were hosted for the 32nd year, are a way for the Department, in collaboration with Corobrik, to reward the talent of students. Diedericks said his win was a great honour and worth the many hours he had sacrificed for this course. Having bagged his master’s, Diedericks’s future plans are to work for the City of Bloemfontein as an architect or on an urban level when an opportunity arises.

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.
