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 has a contingency plan for load shedding
2008-02-13
The University of the Free State (UFS) has put in place a contingency plan to ensure that there is minimal disruption to the normal academic operations of its Main Campus in Bloemfontein whenever load shedding occurs.
The plan includes alternative arrangements for certain lectures that fall within the load-shedding schedule provided by Centlec, the emergency power generation for certain lecture halls and buildings, as well as the functioning of the UFS Sasol Library. This is in addition to emergency power equipment that has already been ordered for the larger lecture-hall complexes.
Fortunately, the Qwaqwa Campus has adequate emergency power generation capacity. The situation on the Vista Campus in Bloemfontein is being monitored, but the same guidelines will apply as on the Main Campus.
On the Main Campus in Bloemfontein the following alternative arrangements regarding the timetable for evening classes will come into effect when load shedding occurs:
- An alternative module and venue timetable has been compiled so that classes that cannot take place on weekdays as a result of load shedding can be accommodated on Fridays and Saturdays.
- Classes that are presented in the timeslot 18:10 to 21:00 on Thursdays are alternatively accommodated in the same venues at the same times on a Friday.
- Classes that take place in the timeslot 20:10 to 22:00 on Wednesdays are alternatively accommodated in the timeslot 08:10 to 12:00 on Saturdays, in a few cases in different venues from those scheduled initially.
- After consultation with students, lecturers will decide whether the alternative timetable will apply when load shedding does indeed occur or whether the alternative timetable will be a permanent arrangement.
Some other steps that have been taken regarding the functioning of lecture halls include:
- The design and installation of emergency power equipment in all the large lecture-hall complexes within the next few months. This includes the Examination Centre, Flippie Groenewoud Building, the Stabilis and Genmin lecture halls.
- The ordering of a larger generator for the Agriculture Building to simultaneously provide essential research equipment such as refrigerators, ovens and glasshouses with emergency power.
- An investigation into the optimal utilisation of present emergency power installations.
The purchasing of loose standing equipment such as battery lights, uninterruptible power supplies, loose-standing generators, etc.
The UFS Sasol Library will continue as normal as far as possible though there may be some minor changes as a result of load shedding. The library has an emergency generator that will be used in the event of load shedding to allow students and other users to exit the library. If load shedding occurs during daylight hours, the library will remain open with limited services. If the load shedding occurs after 6 pm (18:00), all users will be allowed to exit and the library will remain closed until the next day.
A comprehensive investigation into the university’s preparedness for and management of long term power interruptions is also receiving attention.
