Biography

Michael Dickson is founder and Chief Technology Officer of Evocra.  He is a highly innovative, solutions focused practitioner of process design, integration, automation, and implementation, with a distinct passion for fly fishing. In 2010, Michael designed the OCRA Process after being asked to assess a complex acid mine drainage problem on top of a mountain in a world heritage area on the west coast of Tasmania. This plant was installed in 2011, and last year Evocra started up a plant in Brisbane treating a highly-contaminated mixture of organic chemicals and sewage/stormwater.

Abstract

OCRA water treatment technology breakthrough for cleaning up acid mine drainage

OCRA is a new technology for water treatment. Developed in Australia, it uses small amounts of ozone to generate stable bubbles of fine size, and a range of oxidising or reducing conditions. The key is to realise that water can be much more than an inert medium. By adjusting pH and oxidation-reduction potential (ORP) we can achieve surprising results for metals removal and flotation selectivity. Hatch and Evocra are exploring opportunities for applications of OCRA to treat mining-affected waters.
