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.

Global Leadership Summit takes a look at Higher Education in the South African context
2012-07-10

Since 1994 South Africa has achieved a lot in making higher education accessible to South Africans, but challenges still face us daily.

This was the message of a lecture by Dr Lis Lange, Senior Director at the Directorate for Institutional Research and Academic Planning (DIRAP) today at the Global Leadership Summit at the University of the Free State (UFS).

Dr Lange’s lecture focused on the Higher Education and Leadership for Change in South Africa.

In her lecture Dr Lange said in 1994 about 525 000 students, of which 47% were white students, enrolled in South African universities. White youth participation in South Africa was also far higher at 70% comparing to the 9% participation by African youth.

Dr Lange found that eighteen years into democracy, about 900 000 students enrol in South African universities of which the majority is African students. The number of female students also increased greatly.

“In general, youth participation in South Africa remains low. This is still more prevalent among African youth. We also experience a high drop-out rate in South African institutions of higher education.”

Dr Lange delivered this lecture on Monday as part of a series of conversations taking place at the UFS during the Global Leadership Summit. About 160 student and staff delegates are attending this summit and will take part in various critical dialogues.
