This fluoride dosing upgrade project was initiated to upgrade aging infrastructure at the Colac WTP, which had reached its design life and was becoming unsafe to use.
The project delivered:
- Simplification of the dosing system by removal of redundant valves, flush points and instrumentation
- Provision of two dosing panels to provide duty/standby capability. Each panel was provided with;
- Dosing pumps
- Pressure indicators
- Pulsation dampeners
- Pressure transmitters
- FSA flow meters
- Pressure sustaining valves
- Reduction of dosing pipeline diameter where appropriate to minimise the volume of chemical in the system during maintenance activities (e.g. flushing pipes)
- Addition to each FSA day tank of an ultrasonic level transmitter (already implemented at Colac WTP at the time of this review)
