A very enthusiastic well done to Lesego Siwela, who graduated from the University of Pretoria last month with her Batchelor of Engineering (metallurgical) degree.
Although it has been an interesting challenge to mentor a student throughout lockdown, she has done admirably. Lesego worked on an incredibly varied set of projects, bouncing from hydrometallurgy (copper and gold recovery and cobalt leaching) to food processing (colour removal from sugar and inversion of glucose syrup) to development of analytical methods for our internal laboratory.

Cwenga Technologies has been granted essential services status by CIPC as a supplier into the food production and water purification industries. This means that during the COVID-19 South African lockdown, we are able to continue all our functions.
While most of what we do can be achieved remotely, it is a relief that we can continue to support our customers throughout this time in whatever capacity is necessary.
Using a strong base anion resin to remove sulphuric acid from ammonium sulphate solution through acid retardation” presented by Busisiwe Silwana from Cwenga Technologies at the 4th Young Professionals Conference
Dec 24 , 2018
I am Busisiwe Silwana, an intern at Cwenga Technologies. I completed my research project as a pre-requisite for obtaining my BTech in chemical engineering at the University of Johannesburg with the much appreciated assistance of Jenny Hardwick and Ed Hardwick from Cwenga. This research involved investigating the use of strong base anion resins to remove sulphuric acid from ammonium sulphate by acid retardation. The removal of sulfuric acid from ammonium sulphate using strongly basic anion exchange resins by acid retardation has not been widely reported; this is therefore a novel process.
