Kweku
From Bloemfontein to Bremen: Kweku Gavor represented South Africa well in Germany.

It all started with the Umoja Buddy Programme (UBP). Kweku Gavor was a UBP ambassador when he met exchange students from Germany. Two years later, the roles were reversed. “Helping out students who later have become my really good friends opened up the opportunity for me to study abroad in Germany.” he said.

Kweku spent about four months as part of a pilot Summer Lab Programme at Universität Bremen after being nominated for a scholarship by the German Academic Exchange Service, which his former Umoja buddies helped create. He shared the experience with eight other students from Palestine, Poland, Ukraine, and the US. The focus was on Business Studies, Marketing and Economics.

According to the BCom graduate, studying internationally gave him new insights. “The experience opened my mind and better-equipped me to work in situations in which I need to handle a lot of pressure against the clock.”

The first leg of the programme featured corresponding modules presented in a classroom environment, which were integrated with assignments, presentations, tests and exams. This was supplemented by a language course that involved cultural leadership training. Another crucial part of the Summer Lab Programme was an internship where students were placed with companies and tasked with a problem-solving project. Kweku was placed at Fabular Ai, an artificial intelligence company which designs computer software.

“Going to study abroad is an extremely rare and fantastic opportunity I advise all who can to grab it with both hands,” said Kweku, who also used the opportunity to travel all over Europe.

Internationalisation at home with Umoja

The UBP, which is collaboratively run by the UFS Office for International Affairs and Student Affairs, played a big part in Kweku being given the opportunity to study abroad. However, unlike him, not all students have to the opportunity to engage in undergraduate exchanges.

The UBP is part of the university’s efforts to advance internationalisation at home, as anchored in the UFS Strategic Plan: 2018-2022. With the programme, students are able to receive an international experience on home ground.

The programme aims to connect international and local students through meaningful lifelong friendships and foster their academic, social and cultural integration. It pairs first-entry international students with senior Kovsies who provide a warm, welcoming, friendly face, and a helping hand.

Expression of interest sought

A total of 48 ambassadors were enrolled in 2019. To join the UBP in 2020, contact Sonya Kapfumvuti at KapfumvutiSCR@ufs.ac.za or call her on 051 401 3397.

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.
