Large capacity twin water softener in regional hospital to protect the mechanical systems
When sizing a commercial water softener, doing the math and getting a reasonable forecast of volume demand in gallons is critical. Water softening resin has a finite amount of capacity before it needs to go into a backwash (or self cleaning) cycle. Additionally, determining the size of the brine tank for softener salt storage is also very important. This will keep the tank filling requirements at a reasonable level for the personnel maintaining the system..

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 the system.
WHEN TWO COMMERCIAL WATER SOFTENERS ARE NEEDED
In a hospital setting where water is being used essentially 24 hours per day, a back up softener may be required. When one softener goes into its backwash cycle, the backup will provide a steady supply of softened water. Without this backup, unsoftened 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.
