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.

Team UFS flexes its debating muscles

Friday 24 July 2015 marks the day when the University of the Free State Debating Society (UFDS) outperformed the University of Cape Town (UCT) at the UCT 150th anniversary celebration of its debating union.

Representing Kovsies were Zola Valashiya, Ntsapi ‘Neko, Nkahiseng Ralepeli, Lehakoe Masedi, and Thabang Thembani, who fought bravely for a spot in the finals.

Masedi and Ralepeli broke into the semifinals after seven preliminary rounds, eventually winning the competition. The two students were up against three UCT teams, comprising the current National Champions and Pan African finalists.

This follows the debaters’ outstanding performance at the 2015 South African National University Debating Championship (SANUDC), hosted by the University of Venda. The UFDS commemorated a decade in existence by participating in its 10th national tournament.

After nine preliminary rounds, two teams broke into the grand finals of the two categories: English as a second language (ESL) and English as a first language (EFL). Devon Watson and Nkahiseng Ralepeli were the EFL team who fought their way through to the finals, beating UCT and the University of Botswana.

The inaugural Wits Women’s Debate Open (2014) title holders, Lerato Leteane and Lehakoe Masedi, represented Kovsies as the ESL finalists against the University of Nambia. The ladies rose to the occasion, but eventually emerged just one point short of the Namibian team’s four-point win.

Nonetheless, they were satisfied with their competitive skills, utilising the platform to address the lack of female debaters in the Southern African debating circuit.
