What is Water Softener Regeneration Cycle

A water softener is solely used for the purpose of treating hard water which is important to lead a healthy lifestyle and increase the lifespan of our appliances and apparels. Resins are used in water softener to attract the ions and minerals responsible for hardness and old into them. They trap the minerals which are later removed to treat the water into soft water. However, over a period of time these resins get completely covered by the hardness minerals and backwashing of water commences. Regeneration is thus required to clean the resins and make them clean and ready for the softening process again. You can read the full coverage on this page to know more about water softener regeneration cycle.


When does the water softener need regeneration?

A water softener starts regenerating when the control valve indicates the process. There are two types of regeneration that are using in softening of water depending on the type of the control valve installed.

  1. Time-initiated Regeneration: In this type, the clock of the control valve is set to help the system regenerate at periodic intervals of day and time. It is a default setting and the process usually repeats itself at least once a week. This time and frequency of the setting the clock on the valve are done by a professional based on the resin tank’s size, water usage and the total number of people using it.
  2. Demand Regeneration Settings: In this type, the valve of the softener system maintains a track of the water usage and sends the system into the regeneration mode after reaching a predefined amount of water exhaustion. It works on the basis of the amount of water used already and hence calculates the backwash time accordingly and sends the systems for regeneration.

According to reviews, demand regeneration has been very efficient considering both salt and water usage. It is a system generated the prompt and hence time indicated and auto-regeneration initiated is always more accurate.

Time and Frequency of Regeneration

The time and frequency of the water softener regeneration cycle are controlled by the valve of the water softener. This valve is the main control unit which indicates as to when the regeneration process must be initiated.  During the process of regeneration, the water softener systems gush out with the heavy flow of brine water to the resins to clean them off the hardness minerals.

What is the Calculation of Regeneration or Recharge Cycle

Generally, the manufacturer provides a frequency chart along with the maintenance instructions which indicate the recharge cycle of the systems. The parameters considered calculating the recharge cycle are as follows.

Total no. of Days between Water Softener Recharge Cycles = N

Maximum capacity of system’s tank in grams of NaCl or CaCO3 = C

Total Volume of water passing that is passed through the tank per day = Q (Kiloliters per day).

Incoming water’s hardness measured in in PPM = H

N = C / (H x Q)

This is the generic calculation to set your regeneration frequency.
