The Kovsie Annerie Dercksen is one of South Africa’s most promising youngsters and climbing the cricketing ladder.

She enjoyed every second of playing with some of her heroes and believes the exposure to international cricket will help her become a better player.

Annerie Dercksen is one of South Africa’s most promising youngsters and climbing the cricketing ladder.

Star from Beaufort West

This second-year Education student from the University of the Free State (UFS), who dreams of playing for the Momentum Proteas, represented the South African Emerging Women’s team three times in 2021.

The star from Beaufort West toured with the side to Bangladesh and also played against Zimbabwe and Thailand in One Day and T20 matches.

According to Dercksen, it is an incredible honour and privilege to be a part of a side.

She soaked up the experience and says everyone was willing to share their knowledge.

“I would have to say, sharing the field with some of my heroes and getting to work with some of the best coaches in the country are some of the highlights.”

She says each tour brought its own challenges and this helped her grow in the way she views and approaches the game.

“In Bangladesh we played against a well-established team in foreign conditions while facing a lot of spinners in spin friendly conditions. Personally, it was quite a challenge and I had to come back and work on some options, especially against spin.”

“Each tour brought its own challenges and this helped me grow in the way I view and approach the game.” - Annerie Dercksen

Coming through the ranks

The all-rounder has come through the ranks. She represented South-Western Districts at school level, played for the South African U19 side and is currently representing the Free State.

But Dercksen didn’t always dream cricket, especially not when playing ‘backyard’ cricket with her brother on the farm.

She didn’t even play for a team at school. “Until a boy from our primary school’s team got sick before a game. A teacher came to class and asked, ‘who can play cricket’, and I put up my hand.”

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.
