Patents
Dr Mariana Erasmus, SAENSE Platform Manager, says water remediation is vital for both the ecosystem and industries.

KovsieInnovation at the UFS supports innovative research outputs in various ways – one of which is to protect the intellectual property and to register patents where viable. This is in line with KovsieInnovation’s broader aim to create third-stream income for the university. Patent registration is a complex process and the UFS is proud to have the needed expertise to properly facilitate such an endeavour.

The SAENSE Platform

South Africa is a water-scarce country, with many water hungry industries (such as agriculture and mining). “Industrial processes often contaminate water with heavy metals, harmful chemicals, radioactive waste, and even organic sludge,” Dr Mariana Erasmus, SAENSE Platform Manager, explains.

Hence, water remediation is vital for both the ecosystem and industries. One of the key functions of the SAENSE Platform is to offer water-remedial solutions for the (bio)remediation of nitrates, heavy metals, and salts, among others. The platform’s activities and services are supported by undergraduate and postgraduate students and researchers, using Technology Innovation Agency (TIA) funding. TIA is a national public entity that serves as key institutional intervention to bridge the innovation chasm between research and development.

From waste to water

Through the joint effort of two mining companies and the UFS/TIA SAENSE Research Platform, a new treatment for mine drainage (MD) has been developed. This patented B-DAS (Barium – Dispersed Alkaline Substrate) technology effectively treats the major contaminants found in acid, alkaline, or neutral mining wastewater. The aim of the B-DAS system is to provide a passive water-treatment solution with minimum waste production; it can also be a potential pre-treatment for reverse osmosis (RO) to lower the requirements of the membranes and therefore potentially reduce the RO cost.

The success of the patent is that it turns unusable water into water that is fit for agricultural purposes at a reduced cost and increased efficiency.

Mandela statues and the issue of public representation
2015-09-04

   

Prof Grant Parker, Associate Professor of Classics and Co-Director of the Centre for African Studies at Stanford University, USA, presented a public lecture on the Bloemfontein Campus on 27 August 2015, in which he explored the topic of ”Memorialising Mandela after Rhodes Must Fall”. What stories do the multitude of Mandela statues tell us about the man? Our society? Ourselves? These were some of the questions Prof Parker addressed during his lecture.

Paradoxes
Prof Parker discussed some of the paradoxes presented by the Mandela statues. The huge 9m high Mandela statue at the Union Buildings in Pretoria does not necessarily reflect his humility. Iconic statues strewn across the world do not reveal Madiba’s appeal. “Madiba’s charm,” Prof Parker said, “was all about his ability to relate to people of very different backgrounds. People who were his enemies would – to their surprise – find a humanity they were not expecting. It’s very hard to reconcile that with the colossal statues.”

Rhodes Must Fall
On the topic of the Rhodes Must Fall campaign, Prof Parker said that “the debates around it seem to express the frustration of deepening equality in general and lack of demographic change.” He also believes that, although the campaign centres on statues, there are much deeper issues at play that need to be addressed.

Artists should be part of the conversation
Prof Parker also advocated that artists’ voices should be incorporated into the creative processes of public art. “There is a much greater need for creative artists,” he concluded, “to be part of conversations, not only about what we as South Africans want to commemorate, but how we do that. I would very strongly suggest that this be done by non-figural representations.”
