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 interior perforated aluminium planetarium dome has been installed by an American expert from Astro-Tec, the American company that customised the dome for the planetarium on Naval Hill. The planetarium, the first digital planetarium in sub-Saharan Africa, is scheduled to open in November 2013. The UFS manages the project.
The dome arrived in parts by ship from the USA in June 2013. These parts consisted of a number of long curved ‘ribs’ and numerous perforated panels. The panels were attached in sections to the ribs to form a smooth concave shell, creating the surface for the projection system.
The next step will be the installation of the projection system itself.
The 86-year old Lamont-Hussey Observatory on Naval Hill, also known as the Sterrewag Theatre, is home to the planetarium. The planetarium is the first component of a proposed Centre for Earth and Space. This will be a multi-purpose facility to promote science communication and preservation, and the arts.
This project is a long-term partnership between three main organisations, each bringing essential components to the project: the Mangaung Metro Municipality (MMM) as the land-owner, the Free State Department of Economic Development, Tourism and Environmental Affairs (DETEA) and the UFS, which developed the concept for the planetarium project and will be responsible for its operation and further fundraising endeavours.
The National Department of Science and Technology also joined this venture subsequent to providing substantial funding to the UFS in order to purchase the projection system for the planetarium.
