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.

“The University of the Free State is a caring community where everybody counts.” With this message, Dr Choice Makhetha, Vice-Rector: External Relations welcomed our first-years on the Qwaqwa Campus.

“Whether you are a first-year or a senior student, whether you are a cleaner or a research professor, we all have one thing in common: our humanity,” Dr Makhetha said.

“This is the stage where you are going to shape the person you want to be,” Dr Makhetha said to the audience of eager first-year students who had already spent a week undergoing a rigorous Gateway Orientation programme.

“A lot of things will happen during your stay here and one of them is making friends. Make friends with people from outside your comfort zone,” Dr Makhetha added. “Make friends with those who have a totally different background from yours so that you can learn, broaden and enrich your life.”

“Read broadly and ask questions – for questions will take you far beyond your area of study,” she said.

Zethu Mhlongo, Deputy President of the Qwaqwa Campus Student Representative Council (SRC) encouraged first-years to always remember why they chose our university in the first place.

“Enjoy your stay, get your degree and step up for success,” Mhlongo said.
