The technology behind a commercial water softener is the same for a house as it is for a large hospital, however, differences in volume requirements make the design, installation, and service more complicated for a commercial installation in Westwood.
To properly specify a water softening system, getting a reasonable volume demand forecast in gallons is important in determining the size of the commercial water softening system. Water softening resin is limited in the amount of water that it can soften before it needs to go into a backwash (or self cleaning) cycle to clean the resin beads for continued softening. Determining the size of the brine tank for softener salt storage is also very important to keep the tank filling requirements at a reasonable level for maintenance.
Space available for the equipment is another important consideration. To avoid a long piping run to and from the system, a good location needs to be selected. Additionally, any space restrictions will need to taken into consideration when sizing both the softener and brine tank sizes.
WHEN & WHY TWO COMMERCIAL WATER SOFTENERS ARE SPECIFIED
In a hospital setting or other setting where water is being used essentially 24 hours per day, a back up softener may be required. The main reason for this is when one softener goes into its backwash cycle, the second softener will be able to provide a steady supply of softened water to the facility. Without this backup, unconditioned water will be pulled through the system while the softener is in the backwash cycle. In the photo at the top of the page, this system is feeding make-up water to the boiler. It has to be clean water 24 hours a day.
