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.

Recognising academic excellence at the University of the Free State (UFS), the world’s biggest academic honour society, Golden Key International Honour Society, selected a record number of Kovsie students as new members this year.

More than 700 top achievers have been invited to join the prestige academic society – the biggest crop of students thus far.

New members, the top 15% of academic students at Kovsies, were welcomed to the society’s UFS Chapter at an induction ceremony held on Saturday 25 August 2012. The ceremony also saw Justice Ian van der Merwe, Chairperson of the UFS Council, Mr Billyboy Ramahlele, Director Community Engagement, and Prof. Hendrik Swart, Senior Professor in Physics at the UFS being recognised as honorary members of the society. The event, held at the Kovsie Church, drew a large crowd with the venue packed to capacity.

Sibusiso Tshabalala, a third-year BCom Law student, and recently selected as one of ten Google Young Minds for 2012, delivered the keynote address. Structuring his talk around dreams, fears and music, Sibusiso told students they had joined a global community of students who valued academic achievement, leadership and service. “In a country where rhetoric triumphs over logic and mediocrity rules supreme, while excellence is fast becoming taboo, we need the thinkers to do the leading.”

Dr Derek Swemmer, Registrar and co-advisor of the UFS Chapter, told the students they had demonstrated the ability and now had to fulfil their potential. He was appointed as Chairperson of the society’s governing body in March this year.
