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.

UFS obtains court interdict against protesting students - classes will resume on 22 October 2015
2015-10-21

A court interdict was successfully granted to the University of the Free State (UFS) this afternoon against conduct by anyone who intends to damage the property of the university or who interferes with the rights of others.  Any disruption that happens as from now, will be illegal and the UFS will have the right to call upon the South African Police Service (SAPS) to enforce the interdict.

“The interdict does not prevent students from exercising their right to protest or to use any form of demonstration that does not threaten people or property. In doing this, management believes that it is in keeping with its double responsibility of guaranteeing all students’ rights and safeguarding the university’s staff, academic activities and property,” says Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.

“The university management is still open to engage with students in discussing the implications of their demands for a zero percent fee increase,” says Prof Jansen.

All three campuses of the UFS will be open tomorrow (22 October 2015) and all academic programmes and support services will resume as normal. Order will be maintained on the campuses, using the powers of the interdict. No one will be allowed to enter or exit the campuses without a valid UFS staff or student card.
