Donovan Wright
Donovan Wright is currently pursuing his PhD in South African Sign Language linguistics at the UFS.

Donovan Wright recently joined the University of the Free State (UFS) as a lecturer in the Department of South African Sign Language (SASL) and Deaf Studies. As a passionate young academic, Wright ‘found his love’ for SASL during his undergraduate years at the University of the Witwatersrand (Wits). 

In 2016, for the fulfilment of his master’s degree at Wits, Wright completed a thesis titled ‘A preliminary description of South African Sign Language syntax’. He is currently pursuing his PhD at Wits, and his research interests lie in the linguistics of SASL, which became his focus during his postgraduate studies. In his PhD research he focuses on (particular) constructions within SASL and how to best describe and analyse them. “I chose to use an approach to language and grammar not tied to how we perceive and understand spoken languages,” he says. 

‘Teaching SASL is my great passion’

His appointment as a SASL lecturer at the UFS is a fulfilment of his passion for teaching. “Sign languages are commonly misunderstood and thought to be pantomime or gesture,” he says.  “These common misconceptions are the first topic we tackle – whether by linguistic or social argument.” As a SASL linguistics lecturer he says it’s this aspect of the modules that is so rewarding, especially “seeing students realise something new about a sign they already know and have been using. Learning about language while learning a language has its benefits.” 

Empowering students is about access

Wright says access to education is a fundamental right for every student, and that empowering Deaf scholars will ultimately improve how Deaf students access information at universities and elsewhere. “While many students attend university and access their education in a language that is not their mother tongue, Deaf students using SASL are additionally learning across modalities.” 

September is designated as Deaf Awareness Month, with one important aim being to highlight and improve sign language education. The Department of South African Sign Language and Deaf Studies has planned numerous events and initiatives during this month, which will raise awareness and provide community education by visiting schools.  

“The next step is ensuring an environment in which Deaf students who choose to pursue a career in academia are not hindered. Our Deaf students are our future Deaf academics,” Wright says. 

• Members of the Department of South African Sign Language and Deaf Studies will, among other planned events, provide community interpreting services and visit schools in surrounding areas. This year the department is launching a university ‘Deaf Space’ where students, staff, or anyone wishing to engage in SASL can interact, provided you ‘leave your voice at the door’.

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.
