In-line drinking water treatment at Dalby Hospital (QLD)
In a true in-line treatment, the water is treated by passing through a treatment unit: there is no recirculation and for this reason the treatment units must be able to handle even significant flow rates.
Mains water is supplied to the hospital via two meters: the one located off Swan Street serves the majority of the hospital (estimated peak flow rate of ∼10 L/s), whilst the second, very close to Hospital Road, is mainly dedicated to the maternity ward (estimated peak flow rate of ∼6 L/s).
The desired chlorine production at the meters is approximately 2 mg/L.
The information reported in the following table are estimated based on the data collected by the respective control panels:
| Main water meter (Swan Street) | Second water meter (Hospital Road) | |
| Period | from 08/08/2023 to 17/03/2025 (584 days) | from 09/06/2023 to 17/03/2025 (645 days) |
| Water treated | 24,857 kL | 7,852 kL |
| Average cell current | 22.1 A | 8.5 A |
| Average cell potential | 3.5 V | 2.5 V |
| Daily consumptions | 42.6 kL, 23.5 hours of runtime, ~1.8 kWh | 12.2kL, ~10 hours of runtime, <0.5 kWh |
