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.

“This also bodes well for my two main distances." This is what Wayde van Niekerk said according to www.iaaf.org, after running a personal best time of 9.94 in the 100 m in Velenje, Slovenia, on 20 June 2017. The Kovsie athlete improved his previous best by 0.04 seconds at the 22nd International Athletics Meeting.
Van Niekerk was referring to the other distances in which he excels – the 200 m and 400 m. The 400 m world record-holder said he was pleased with his latest run: "It's my best time and I'm glad the competition ended the way I wanted it to.”
National 200 m record and world’s fastest in 2017
His feat in the 100 m was his latest success, as he recently became the national record-holder in the 200 m again, and also the fastest man on the planet in this distance in 2017. After he ran a 19.90, the world’s fastest this year, when he won the South African title in Potchefstroom in April, the American Christian Coleman (19.85) improved on that.
However, Van Niekerk ran a 19.84 in the 200 m at the Racers Grand Prix in Kingston, Jamaica, on 11 June 2017. This was 0.06 seconds quicker than his personal best, and 0.03 seconds better than Anaso Jobodwana’s national record of 19.87.
Same pace a second time in a week
It was also the second time in a week that he ran a 19.84 in the 200 m. This after he did it on a temporary built track at the Boost Boston Games on 4 June 2017. The race was run on a straight street course and was therefore not officially recognised as a record.
He seems to be in good shape leading up to his attempt to run a double, his favourite 400 m and the 200 m, at the World Championships in London, England, in August.
