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.
Young Shimla team reach Varsity Cup semi-final

on form in the 2017 Varsity Cup semi-final against
Tuks in Pretoria.

The pressure in the Varsity Cup semi-final is on Tuks, which will be reason enough for Shimlas to play with freedom.
This is according to Jaco Swanepoel, Shimla assistant coach, on the big challenge awaiting his young rugby team in Pretoria on 3 April 2017. He says because Tuks are the favourites, it could be to the advantage of the visitors. Maties and the University of Johannesburg are playing in the other semi-final in Stellenbosch on the same day.
Tuks did Shimlas a favour
Tuks’ victory of 43-28 over the Pukke in Potchefstroom on 27 March 2017 helped the Shimlas, who had a bye, to end fourth on the log with 23 league points.
Shimlas had to make use of several new players this year, and few experts would have given them a chance of reaching the semi-finals. Swanepoel says although they are proud of this achievement, only a place among the top four was never their end-goal.
Good to be the underdog
The Shimlas lost their league match against Tuks in Bloemfontein with 19-65. This, as well as the fact that Tuks was at the top of the log with 34 league points, underlines the huge task ahead.
“The previous result (against Tuks) is encouragement for the players to show: We aren’t that much worse than Tuks,” says Swanepoel. “Perhaps it is good to be the underdog. We actually have no pressure on us and I hope the players feel the same way.”
Three teams in knockout matches
All three Varsity Cup teams from the University of the Free State (UFS) reached the knockout matches. Apart from Shimlas, the UFS Young Guns played against Tuks in a semi-final in Bloemfontein on 27 March 2017, but lost by 21-45. On 17 April 2017, Vishuis will meet the Puk’s Patria in the residence finals.
