Water Treatment FAQs

What is regeneration?

With water softeners, regeneration is the process of “recharging” the resin beads when they are “full” of nothing but calcium and magnesium and have lost their softening capability. Regeneration is “triggered” by a number of ways. If a softener regenerates after a certain period of time it is called time clock regeneration. Systems set to run after a specific number of gallons have been used are referred to as metered.

However, one of the most effective regeneration techniques uses Smart-Sensor® technology, which is based on actual demand. Smart Sensors work by measuring the conductivity of the resin bed. As the resin becomes coated with calcium and manganese, it creates a change in conductivity. That triggers the softener to regenerate. It is especially valuable when water hardness varies from day-to-day.
