iCAN read more — The book was launched during the Student Arts and Life Dialogues Festival on the Bloemfontein Campus in October.

In its continued bid to decolonise the academic curriculum at the University of the Free State (UFS) the Centre for Teaching and Learning (CTL) published the second volume of Creative African Narratives (iCAN) short stories written by UFS students.

iCAN Volume 2 comes after extensive creative writing workshops were presented on all three campuses during the year. The project is coordinated by Dr Peet van Aardt from CTL and is funded by the Andrew W Mellon Foundation.

Through the iCAN project, CTL plans to incorporate the students’ written texts as part of the extensive reading component of the first-year academic literacy courses across all faculties. “We are teaching and motivating our students to read, but we cannot keep relying on a curriculum that is foreign to them,” said Dr Van Aardt.

The volume comprises 55 short stories with topics ranging from the Struggle, to campus life, mental illness, family affairs and love, with the students’ lived experiences also a main theme throughout the anthology. The stories are written in Sepedi, isiZulu, Setswana, English, Afrikaans and Sesotho. Some were also performed at the recent Multilingual Mokete, held on the Bloemfontein campus in September.

“We are really proud of this year’s publication, and the project as a whole,” says Dr Van Aardt. “This year we were able to include more student contributions than last year.”

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.
