Oupa Mohoje
Oupa Mohoje is the first former Kovsie to be named regular Cheetah captain since Juan Smith in 2008.

Former captain of the Kovsie Shimlas, Oupa Mohoje, was chosen to lead the Free State Cheetahs for the 2018/2019 rugby season.

 

He is the first Kovsie to be the regular Cheetah captain since Juan Smith 10 years ago.

“It certainly is a big honour, but it comes with a lot of responsibilities,” said Oupa. One thing he is glad about, is the fact that the players and the Cheetah coach, Franco Smith, fully support him, which makes his job a lot easier, he explained.

 

“Choosing Oupa as captain came naturally – he is a true favourite with everyone in the team,” said former captain, Juan. Oupa grew up in the Free State, he studied here and became a Springbok here, and that makes him a Free State player through and through, explained Juan.

 

From Shimlas to Springboks in three months, Mohoje, a loose forward who can also assist as lock, captained the South African A side in 2017, and the Shimlas in 2013. He represented the Shimlas between 2011 and 2014 and was voted the Player of the Varsity Cup in 2013. His final match in the famous blue jersey was on 17 March 2014. A little more than three months later he became a Springbok, playing the first of 19 tests.

 

According to Harold Verster, Managing Director of the Cheetahs, Oupa is very popular among the players, he is very disciplined, and has all the qualities to make a great captain.

 

Oupa’s teammate Ox Nche added, “He has good people skills and communicates very well. I think he is a very good leader”.

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.
