Qwaqwa Campus has a new student newsletter. According to the Editor-in-Chief, Prudence Mkhari, New Era aims to project content that is written from a student’s perspective. 

“We want students to easily relate to the content as opposed to being written by a staff member. It focuses on student-life events and the university as a whole. The content ranges from student life to university events and milestones. In essence, it is the voice of the students and the watchdog of the campus,” says Prudence.

She says response to the newspaper has been good, considering that they have had only two issues plus an SRC election special that carried candidates’ manifestos. “We are constantly being asked when the next issue is coming out. A lot of students have even come forth with stories that they would like us to cover in the next issue,” she added.

Some of the comments about the very first edition includes this one by Rosie Senoko, final-year BA student: “Congratulations on your publication. One would swear that you have written many pieces, not aware it was your first! All the best to you and your team.” A BSocSci final-year student, Sibonginkosi Ngcongwane, wrote: “Great job! Well done!”
It has not been an entirely smooth sailing process for the paper. “There is still room for improvement in terms of writing and editing, because almost no-one on the team has writing experience. So, additional training is still required. Meeting deadlines is also another area that needs major improvement,” says Prudence.

The team comprises 14 students who write a variety of pieces, from news to sports and from opinion to lifestyle, while some provide technical support such as editing and photography. 

Going forward, the plan is to digitise the newspaper and make it accessible to a broader online market. To advertise, send an email to newera@ufs4life.ac.za

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.
