Wellington Water

CFD modelling enabled a solution to be designed and validated offline, without plant interruptions.

Our Role

Process Modelling

We were engaged to determine the T10 contact time for the Chlorine Contact Tank at the 140 ML/d Te Marua WTP and the 60 ML/d Wainuiomata WTP using CFD modelling. The results showed that the Te Marua tank was compliant with the DWSNZ2008 for all scenarios, whereas the Wainuiomata WTP had an issue under the worst case scenario. Modifications were modelled and a solution implemented.
