Professional
experience (short
description)
My experience in water and wastewater treatment has been varied and extensive
and has involved both practical investigations for designs and upgrades to water
and wastewater works, optimisation of various processes and troubleshooting. In
addition I have been involved in a number of research projects, many through the
Water Research Commission, but also a number of internal projects.
