What is the minimum time between regenerations?
Operationally softeners should be regenerated at 6 hour intervals. (6 to 12 hours is used for design purposes) Discussion: The minimum time between regenerations is first set by the regeneration cycle, which is usually two hours. The other issue is the recovery time of the brine tank. After brining, the brine tank must refill and then the salt must dissolve to create a saturated brine. The minimum time is generally set at six hours which is two hours for the regeneration cycle and four hours for the brine tank to recover.
