Dr Karen Lazenby strives for a stronger, rule-based, and consistent governance structure.
A transformed University of the Free State (UFS) will be one that promotes social justice in everything it does, a university where its diverse people feel a sense of common purpose and engagement. The UFS is developing this through its Integrated Transformation Plan (ITP) introduced in January 2017. 

“The majority of the current systems and processes in student administration at the university are still manual. This lack of automation leads to inconsistencies and service failures,” says Dr Karen Lazenby. As Registrar for Systems and Administration, Dr Lazenby is responsible for ensuring a smooth and efficient student lifecycle across all three campuses. 

With the ITP, the Governance: Systems and Administration work stream strives to have a stronger, rule-based, and consistent governance structure with a single line of accountability in student administration across all faculties and relevant support departments on the three campuses. By ensuring this ease of use and access there will be an integrated student experience and greater empowerment of students.

“Our focus is on automation and self-services for students (such as the time-table, requests for additional and ad hoc exams and appeals), to ensure transparency and accessibility of rules and policies, decisions relating to admission, progression rules, awarding of qualifications and graduation and faculty and general rules,” Dr Lazenby said.  It will also entail the optimisation of PeopleSoftCampus (the Enterprise Resource Planning system).

“Through this automation, I would also like to get the university’s student administration to such a level that academic staff can focus their energy on teaching and research and student administration staff can focus more on quality assurance,” said Dr Lazenby.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
