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.

Amphitheatre to energise student life on the Qwaqwa Campus
2015-06-11

The Qwaqwa Campus of the University of the Free State is one of the fastest-growing rural campuses.

Since 2010, the campus has, among other things, built two new student residences, which provide accommodation for an additional 500 students. The old disused boiler room, which was used as a storeroom, has been converted into much-needed ablution and dressing room facilities at the sports fields.  The Faculty of Education now boasts a Technology, Engineering Graphics and Design Education laboratory. The project was funded by the Department of Higher Education and Training.

One of the student priorities is a common space in the form of an open amphitheatre in front of the library.

‘’The amphitheatre is a highly-welcomed structure on our campus as it will provide students with an informal environment to study, socialise and meet,’’ said the Campus Principal, Prof Prakash Naidoo.

‘‘We have erected this on an existing space that was already used for outdoor launches and events on the campus, and is in line with our thinking of energising student life on campus. In addition, we have complemented this with the use of solar energy, so that students can just plug in and charge their phones and laptops while they are in the amphitheatre.”

Excited students, Chibi Mosia and Tshilidzi Matshavha, in final-year Chemistry and Chemistry Honours respectively, concurred that the amphitheatre is a good project for the campus.

‘‘It is an important and distinctive feature for the campus as it adds to the growth of our beautiful campus,’’ said Mosia.

‘’It will also enhance the use of alternative energy sources to reduce the campus's carbon footprint,’’ added Matshavha.

The project is worth almost R2,5 m, and took 12 months to complete. The Department of Higher Education and Training also provided the funds for this project.
