Inaugural Dreamwalk 2022
The inaugural dream walk put students in high spirits for the rest of the year, as they were able to express and celebrate their dreams and aspirations.

The inaugural dream walk at the University of the Free State took place on the Bloemfontein Campus on 19 February 2022. The dream walk, also referred to as ‘Leeto la ditoro’, will become an annual event where first-year students come together to express and celebrate their dreams and aspirations. 

The event was well attended by Bloemfontein Campus first-year students, who believe that the event is a great way to set the tone for the rest of the year. The students first gathered at a station on campus, where they were issued with a faculty T-shirt, key chain, a dream card, and a mask. The official walk then began from the Visitor Centre Gate on the northwest side of the Bloemfontein Campus to the Main Building, where members of the senior leadership are based.
During the walk, first-year students had to write down their dreams and aspirations on the dream card, which they ultimately placed in a box at the Main Building. “I found it amazing to be able to put my dreams on paper; it makes them more realistic,” highlighted Marise Prinsloo, a first-year student from the Outeniqua residence. Although some of the aspirations were too personal for some first-year students to speak about, others’ aspirations varied from academic success, spiritual wellness, and mental and physical health. In fact, Malcolm Willemse, who is also a first-year student from Outeniqua, hopes to secure a number of leadership positions. “I have dreams of being in the first-year committee and of being in the sub-committees, and I managed to write these down,” he shared. 

In addition, the atmosphere at the event was vibrant, as the students were excited to engage with one another. “It was amazing to walk with other residences such as Villa Bravado, Abraham Fischer, and Conlaurês, as they have great spirit,’’ expressed Willemse. The walk included songs from the various residences, and the first-year students were dancing and singing along. However, the fun did not end there. Once the students arrived at the Main Building, they were treated to a DJ who had them dancing and singing even more.

As the dream walk event will also take place on the Qwaqwa and South Campuses, the students on these campuses can expect to take part in a lot of singing, dancing, and other cultural activities. Precious Modiba, who is also a first-year student, argues that besides having a good time, one of the best things about the dream walk is the friends that one gets to make.

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.
