WISA 2018

Ed and Jenny presented 2 oral papers and 1 poster presentation at WISA in June.

The first paper, presented by Ed was on Nickel removal from effluent with Columbus stainless. Jenny then presented on spent resin reuse as a pre-treatment to reverse osmosis on behalf of Eskom R&D. Our poster detailed the Cwenga Plant Audit system we've developed to help our utilities customers with plant optimisation and resin management. The papers are available on Researchgate. 

COPESSA and Cwenga

It has been a greatest honour to have worked with COPESSA which was introduced to me by Cwenga. Even though I was with the organisation for a very short period of time I am proud to say I have gained a wealth of knowledge and experience which I will treasure.

I am taking away COPESSA’s vision of creating a safe and secure environment with me to my community and I promise to use this vision to build my own community. It is always nice to work with well envisioned people with positive energy that radiated in me.

My name is Pinkie Delia Motsoeneng, I am 24 years of age and I was on a learnership with Cwenga Technologies (Pty) Ltd. Firstly I would like to thank the organisation for the amazing Learnership opportunity over the last 12 months, when I came to the company I had no experience in business administration, that was until I came across the learnership opportunity that was offered to me.

Cwenga has been a patron of COPESSA for 5 years now. For Cwenga the decision to continue our support of Copessa has been an easy one to make.

Ion Exchange to extract wealth from mine waters

For the IMWA 2016 conference we put together a paper that provides an overview of the potential for recovery of value from contaminated mine waters and waste streams. It discusses various metal ions commonly found in acid mine drainage and other mine waters (mainly Co, Ni, Zn, and U) and evaluates at what concentration they become attractive to investigate for recovery using ion-exchange technology.
