Efficient power consumption per cubic meter
Efficient power consumption per cubic meter
(OP)
I am reviewing the energy demand for a group of water pumping station (potable), the process in most of these stations is based on river intake, coagulation, filtration, storage and distribution pumping.
In most of these stations, throttling is used and the need for VFD arises with potential power factor saving. I wonder if there is a common figure for a kwh/m3 that I can use as a target? the stations metering isn't in the best condition as well!.
Any clue?

RE: Efficient power consumption per cubic meter
No there are too many variables in these sort of installations to use a "common figure."
All i can suggest is you start work on one station and see how much difference various changes make. Use the initial condition as a benchmark. When successful roll out the changes elsewhere.
When you are refferring to the stations metering do you mean the power meters or flow metering?

The big power consumption will be getting the water to the plant and pressurizing the plant effluent to distribution pressure. Water treatment plant generally do not have unit processes that consume large amounts of power with the exception of the RO processes.
