Within this field, David specialises in biological nutrient removal processes, water recycling and biosolids treatment. With an extensive background in Operations, David is especially focussed on operability, maintainability, and process efficiency as key components of successful treatment facilities.
From 2000 to 2006, David was MWH’s Senior Process Engineer in Queensland.
