Dedham Health & Athletic Complex “wanted to transition the water supply for two cooling towers from expensive city water to well water without polluting the water with expensive hazardous chemicals. We also wanted to eliminate calcite scale on heat exchangers caused by hard water from the well supplying the cooling towers.”
A FlowMark Electronic Pulse Power Water Treatment System was installed on two Marley cooling towers and associated heat exchangers. A simple retrofit, the Flowmark coils wrap around the existing pipe and plug into the FlowMark control panel with no down time. New Pulsafeeder Conductivity meters and blow-down valves were also installed to precisely control conductivity levels and save on water & sewer costs.
The results are very impressive:
- Eliminates the use of hazardous chemicals to control bacteria with total bacteria counts of less than 500 CFU/ml.
- Increases cycles of concentration resulting in water and sewer saving of over 21,500 gallons per week.
- Eliminated calcite scale and biofilm for significant savings in energy as well as lowering system cleaning costs.
- Provides corrosion control by using calcium carbonate as a natural corrosion inhibitor.
