Peet Jacobs.

Peet Jacobs is no stranger to the Deaf community in and around the UFS and Bloemfontein. He has been working at the University of the Free State (UFS) for the past six years, and he is still amazed at the amount of support our institution provides to Deaf students in particular, and to South African Sign Language (SASL) in general. “They provide excellent interpreting services,” Peet says, “not only in face-to-face classes, but also on different online platforms, as well as interpreting pre-recorded lectures and videos.” And as a SASL interpreter, Peet is an integral part of this service. 

But signing is not merely a day job for Peet. He carries his skill into the community in his spare time, where he assists as an interpreter at hospitals, doctors’ rooms, and psychiatrists’ offices – to name but a few. What gives Peet the deepest satisfaction, however, is when he can combine his love of Sign Language with his love of the Bible and his God. It was actually Peet’s devotion to his religion that inspired him to learn Sign Language in order to enable him to carry the Word of God into the Deaf community. Peet now also presents Bible courses in SASL and assists a non-profit organisation to produce SASL Bible-based publications, which are translated and recorded in video format. 

Peet aspires to become an authority on SASL subject-specific vocabulary related to subject in higher education. “Sign Language is a language in its own right,” Peet points out. “The uniqueness of Deaf culture and the variety of dialects within SASL give the language diversity and colour.” Peet goes on to emphasise how important it is that SASL is recognised as an official language in our country. “This recognition will give dignity to a group of people who have been marginalised in South Africa. This will also pave the way to providing more inclusivity and service to the Deaf community.”

Until then, Peet will continue to serve the best way he knows how: through signing.

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.
