Ian has 30 years in the water and wastewater industry, covering academic, industrial and consulting research. During his career in wastewater treatment, Ian invented the Captor process and learnt about the hard end of contract engineering at Simon Hartley. He crossed the great divide into drinking water on joining the Water Research Centre and worked through coagulation, oxidation, adsorption, membrane filtration and irradiation, and in the production of mutagenic chlorination by-products.
