“I love teaching hearing people Sign Language,” Emily immediately mentions when asked about herself, “so that they can communicate with Deaf people and work with them.” Part of her passion, though, was borne from personal hardship. Emily had a difficult experience when she entered the work environment in 2000, since she was the only Deaf person among an all-hearing staff. Can one even begin to imagine the frustration and isolation she must have experienced? It is no wonder, then, that her vision is for Deaf people to have equal access to information, and for the hearing and Deaf to be able to communicate with each other more freely. And the latter she is pursuing with all her energy.

“When I started working as a Teaching Assistant in the UFS Department of South African Sign Language (SASL) and Deaf Studies,” Emily recalls, “few students were interested in studying Sign Language, because they were not aware of Deaf people and Sign Language.” This has started to change, though, as Emily is noticing a drastic increase in the number of UFS students enrolling for SASL. “I am now familiar with a lot of hearing student who have done Sign Language at our university, and they are very friendly when I meet them. Also, because they are able to greet me in Sign Language!” It is important to note that the department teaches SASL modules to both Deaf and hearing students (and staff) who want to learn the language – which is now also available as an online option.

As a second-year student studying BEd, Emily has formed a close relationship with CUADS (Centre for Universal Access and Disability Support) at the UFS. “CUADS is doing a great job in assisting students with disabilities and catering for their needs. They assist students to have access to education on the same level as other students without disabilities.”

Sign Language is of vital importance to the Deaf community, since it is the language of accessibility for Deaf people. “We are proud and acknowledge Sign Language as a medium of communication,” says Emily. “It allows us to express ourselves, and to teach and transfer our Deaf culture from one generation to the other.”

Ultimately, Emily is hopeful that Sign Language will become embraced, celebrated, and recognised as equal to the other official languages in South Africa.

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.
