Leading women honoured at faculty opening

At its recent opening, the Faculty of Theology and Religion conferred the inaugural Letsema Award on Dr Ellen Vuyiswa Blekie, a medical doctor known for her sterling work in her local community in Thaba Nchu, as well as on the various church councils and committees on which she still serves at the age of 87. Dr Gideon van der Watt, director of the “Partners in Mission” unit of the Dutch Reformed Church in the Free State, presented the award to Dr Blekie on behalf of the faculty.

The theme of the morning’s proceedings was: The church and violence against women and children. This theme was not only borne out by the worship service presented by Rev Martin Laubscher, but also by each of his participants. First, a popular song from 1987, My Name is Luka, by Suzanne Vega, was recited in spoken-word form. The song deals with themes of physical and emotional abuse, as well as being kept silent as a victim. Next, the Paulette Kelly poem I Got Flowers Today was recited. The final stanza begins with the words “I got flowers today.../Today was a special day — it was the day of my funeral...”

Dr Carin van Schalkwyk, who has been serving the Philippolis community and congregation since 1993, conducted the liturgy. Her chosen passage was 2 Samuel 13, which recounts the events leading up to King David’s son Amnon raping his half-sister Tamar and the subsequent cover-up by the king and his sons. Dr Van Schalkwyk likened the way David of old handled the situation to the modern church’s failure regarding the protection of women and children, stating these vulnerable ones have been failed miserably.

Dr Van Schalkwyk added: “The root of the problem has not been addressed. It requires a rethinking of both preaching and policy, even of theology. All are created in God’s image; what does that mean?”

Concluding, she said, “We need to hear the lament of those affected, and weep with them. I dream of a day when women do not have to think of how to avoid sexual harassment on a daily basis.”

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.
