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.
Trade unionist brings today’s policy issues to the table

Sidney Kgara was appointed to the University of the Free State (UFS) Council in January 2015. He was appointed to the Council by Blade Nzimande, the Minister of Higher Education and Training, in one of three such positions.
Sidney heads the public sector union Nehawu's Policy Unit. The National Health Education and Allied Workers Union is the biggest public-sector union and the biggest union in the public service coordinating bargaining council. It therefore stands to reason that researching and drafting policy on issues such as labour market matters, public health and developments in higher education form the core responsibilities of the unit.
No stranger to university governance and leadership
Nehawu has a number of members working at the UFS and before his appointment, Kgara's only contact with the university was through its UFS members. However, he is no stranger to university governance and leadership. He was a student leader at the University of KwaZulu-Natal in the 1990s and as a result has a broad understanding of student governance and university issues.
"Even though it was a different time and the circumstances were different, there is some sense of continuity to the issues we had to deal with then, and the issues that the university faces now," he says.
Kgara’s unique and valuable contributions to the Council
This, together with his experience in policy and research, enables Kgara to make a unique and valuable contribution to the Council.
Kgara is an avid reader and stimulating his mind through reading makes him truly happy. He also loves watching sport and enjoys socialising with friends.
