Kettering Hospital in Dayton, OH, Wahaso Case Study

Kettering Health Main Campus is a flagship facility serving Ohio and surrounding area. Chemsearch FE and Wahaso were approached by Kettering Hospital management to try and reduce the amount of water they were using for cooling tower makeup.

Another consideration was emergency management in the event the city water lost pressure due to a natural disaster which directly affects their ability to meet operational requirements. Located in the parking structure there is a groundwater collection sump (dewatering sump) disposing water into the storm sewer system. Normal flow rate into the collection cistern is in excess of 40 GPM. This groundwater was previously discharged to sewer. Upon analysis, the water quality was basically good though high in hardness (as CaCO3) In order to reuse this water for cooling tower makeup, the water needed to be treated to remove hardness and reduce overall conductivity.
