Improving Energy Efficiency Of Pumping Stations By Sub-Metering
In most cases a pumping station out in the system, which is used to transfer water to a reservoir or boost the zone, normally only has the pumps and a few auxiliary pieces of equipment, as a result, 95 -97% of the power measured through the billing meter will reflect the demand of the pumps.
However, this approach is insufficient once the load and power demand of either a water or waste water treatment works needs to be considered. In this situation, the incoming energy meter monitors the demand and consumption across the whole site. With any modern treatment plant there are multiple processes, each of which has their own energy demand.
Water Treatment Process
- Low Lift stored water pumping system
- Filter wash water plant
- Sand washing plant
- Ozonation cooling water plant
- Ozone Generators
- High lift Pumping
Waste Water Treatment Process
- Aeration
- Final effluent pumps
- Sludge pumping
