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.
Babies need time on their tummies

Babies who spend more time on their tummies (in the prone position) when they are awake are more advanced in their motor development than children who are not allowed to lie on their tummies, or only for short periods, shows research published by Ms Dorothy Russell in the South African Journal of Occupational Therapy. Ms Russell is a senior occupational therapist in the Department of Paediatrics and Child Health in the Faculty of Heath Sciences at the University of the Free State (UFS). The study shows there were significant differences in the active movements of the arms and the pushing-up on the arms between prone and non-prone infants.
She says research and clinical evidence indicate that parents are not well educated regarding the value of placing their infants in the prone position during the early stages of infancy. The supine position where babies lie on the backs, leads to a decrease in the sudden infant death syndrome (SIDS), and mothers steer away of putting their babies in the prone position because of that. However, lack of exposure to prone position can result in deceased opportunities to learn functions such as rolling over, sitting up, crawling and pulling to the standing position.
