Better yourself at Adelaide Tambo Public Library
According to Dr Magteld Smith the American Space in the Adelaide Tambo Public Library provides an opportunity for visitors to connect and learn about the US.

The new and upgraded American Corner at the Adelaide Tambo Public Library in Bloemfontein is a must visit for all driven individuals who are looking to better themselves. 

"The opportunity the American Corner provides is something all teachers, students and pupils must know about," said Dr Magteld Smith a lecturer and researcher in otorhinolaryngology in the Faculty of Health Sciences at the University of the Free State (UFS). The library, on the corner of Charles and West Burger streets, was renovated recently. As part of the overall renovation project, the US Consulate General in Johannesburg refurbished the Corner and provided new computers and audio/visual equipment to enhance its educational and cultural programmes. It is equipped with the very best audio and online technology for audio- and e-books with free Wi-Fi, said Dr Smith.

The US Consulate General in Johannesburg and the Mangaung Metro Municipality renewed their partnership when the Executive Mayor of Mangaung Metro Cllr. Olly Mlamleli and US Consul General Michael McCarthy signed an agreement for the American Corner Mangaung at the library.

The American Space in the library provides an opportunity for visitors to connect and learn about the US through books, movies, and magazines. It provides a space for information and engagement on issues such as educational advice for those who want to study in the US, workshops on a range of topics from career skills to English language learning and the introduction of 21st-century digital skills, and academic resources for visitors.

Dr Smith said it was essential that teachers, pupils and scholars make use of these opportunities and facilities at the Adelaide Tambo Public Library.

"Very few people know of this," she said.

Dr Smith, who is deaf, was a fellow at the University of Minnesota, Humphrey School of Public Affairs, through the US Department of State.

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.
