UFS Debate Society
The UFS Debate Society led by example at the 2019 Jozi Rumble.

After competing in the Jozi Rumble final for six consecutive years, the UFS Debate Society won the competition – Africa’s largest intercollegiate debate open – for the second consecutive year. The tournament took place at the University of the Witwatersrand (Wits) in April 2019.

After seven preliminary rounds, three UFS teams out of a total of 100 competing teams overall were placed in the top 16, earning them a place in the quarterfinals – where they faced each other. A composite team of UFS LLB graduate and LLM student, Lehakoe Masedi, and a partner from Wits beat all teams, qualified for the final themed ‘This house regrets the glorification of opulence in popular culture’, and won the league.

“It was one of the most validating moments of my entire debating career; everybody wants to win the Jozi Rumble, and to have done it and to be the best speaker is truly amazing,” said Lehakoe. The top-ranking speaker at the tournament added that she had been working hard, and that she is glad that her efforts are coming full circle.

The UFS sent six teams overall to the tournament, including two novice teams competing in their first-ever intercollegiate debate tournament. 

“Speaking at the Jozi Rumble debate tournament for the first time was truly an educational experience; it exposed me to the dynamics of varsity-level debating,” said Simphiwe Yana, debater in of the UFS novice teams.

The UFS speaking squad consisted of Lehakoe Masedi, 2018 Abe Bailey Bursary victor and Rhodes scholarship recipient Nkahiseng Ralepeli, Khotso Khokho, Siyanda Rixana, Morena Moabi, Simphiwe Yana, Luvuyo Shoco, Asemahle Noholoza, and Nontobeko Msimangu. Former Chairperson of the UFS Debate Society and Editor-in-Chief of the IRAWA newspaper, Tshiamo Malatji, was also present at the tournament as the Tabulation Director. 

On 11 May 2019, the UFS will travel to the University of Pretoria to defend yet another debate open title at the Pretoria Parlay Intervarsity.

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.
