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.

Thinking stone artist on his way to Italy
2015-04-29

Willem Boshoff

Professor extraordinary at the UFS Department of Fine Art, Willem Boshoff, together with other South African artists, will represent the country next month at the Venice Biennale.

The 56th Biennale takes place between 9 May and 22 November 2015. It is regarded as the world’s most important art event, with 53 countries taking part. This year the artists will take part in the exhibition entitled What remains is Tomorrow, which will take place in the Arsenal complex in the Italian city of Venice, where it will be on view.

Boshoff was responsible for one of the sculptures known as the Thinking Stone, that may be seen in the middle of the Bloemfontein Campus, in front of the Main Building and next to Red Square.

This work consists of a 32-ton black granite block excavated from the Boschpoort stone quarry in Belfast, Mpumalanga. The block has engravings that are copies of the prehistoric rock paintings (also known as petroglyphs) from Driekopseiland (a prehistoric rock art area near Kimberley). Together with the engravings, on the front of the block, there are sand-blasted inscriptions in six languages of verses and well-known quotations that refer to the word “rock”. These inspire further thought and contemplation. Boshoff has created similar works, including Children of the stars, situated at the Cradle of Mankind.

Boshoff is also known for very innovative and conceptual works, and has created various public artworks, both nationally and internationally. His work includes commissions from the University of Johannesburg, The Constitutional Court, the Mpumalanga Legislature in Nelspruit, and South Africa House in London’s Trafalgar Square.

His work focuses regularly on relationships and social interaction. Generally, they are also the subject of subsequent discussions.
