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.
HIV/AIDS could kill 20% of southern Africa’s farm workers by 2020
2008-09-27
HIV / AIDS is claimed to account for 40% - 50% of infections in the workforce in some labor-intensive industries. This means that every farmer will have to replace up to 50% of his workforce within the next 10 years.
This was said by Mrs Estelle Heideman (pictured) of the Faculty of Natural and Agricultural Science at the University of the Free State (UFS) at the launch of a DVD about a project to equip farm workers with knowledge and skills regarding HIV / AIDS.
Mrs Heideman was quoting the research findings of Agrimark Consultant, Johan Willemse, and added that farm workers, because of low literacy levels, remoteness of the areas in which they live and the distances to health care facilities, are often forgotten when it comes to HIV/AIDS prevention and care programmes.
This weekend Mrs Heideman leaves for New York City to take up a scholarship awarded to her by the University of Columbia and the University of California, Los Angeles (UCLA) to participate in the M-A-C AIDS Sponsored Leadership Programme.
The leadership Initiative provides a structured support program to enable participants to exchange best practices in the approach to HIV prevention that can be adapted to local circumstances. At the conclusion of the program the Leadership Initiative will, amongst other benefits, provide funds for Fellows to carry out their prevention program in South Africa.
Such a program was already carried out from February to May this year as part of the Lengau Agri Centre’s Farm Project in collaboration with the Chief Directorate Community Service at the UFS on the farms Slangfontein, Dwarsrivier and Pypersfontein in the Philippolis district.
According to Mrs Heideman, who is the co-coordinator of the project, the aim of this project was to equip farm workers with knowledge and skills regarding HIV/AIDS so that they can take control of their lives and make quality decisions.
“A major advantage of working with farm workers is that the whole family is included in the session and this ensures that all generations get the same message”, she said.
At the end the feedback from the farm workers about the programme was positive. “Many said they had tested for HIV and will continue to do so to ensure that they would be around to see their children grow up”, said Mrs Heideman.
Copies of the DVD can be obtained from Estelle Heideman (0828211230) or Tarryn Nell (0832573843).
