WATER SOFTENERS

You are about to equip yourself with a softener and you wonder about the chronological regeneration or the volumetric regeneration of a softener?
And for good reason, this is a special feature that you must understand before choosing your equipment. Discover in this article the difference between these two types of softener programmers, their advantages and disadvantages.

Reminder of the operation of a water softener:
The softener is installed at the water inlet of the dwelling to “filter” the limestone water to obtain softened water. The advantage of being equipped with a softener is therefore to be able to benefit from all the benefits and comfort of fresh water and quality.

The operation of the softener is quite simple. It is composed of two tanks: a tank of resin called “ion exchange” and a tank of salt. When the water passes through the softener, the resin will capture the calcium and magnesium ions from the water, which are responsible for the limestone, to replace them with sodium ions. This is called ion exchange.
After a certain volume of filtered water, the resin has yielded all its sodium ions, it reaches saturation of calcium and magnesium: this maximum volume of filtered water is called the capacity of the softener. It is calculated according to the number of cubic meters of the softener and according to the hardness of the water. Thus, when the maximum capacity is reached, the resin needs to recharge in sodium ions present in the salt reservoir: this is regeneration.

The two types of regeneration programmers:
The frequency of regeneration of a softener can be programmed in two ways depending on the type of equipment:
– Chronometric or Chronological: regeneration of the resin at regular intervals
– Volumetric: regeneration of the resin as a function of the water consumed

The timeline regenerator:
A water softener with timer will perform the regenerations at regular time intervals, every 2-3 days for example. Thus, the resin of the softener is regenerated as a function of time, without knowing if it is saturated with calcium magnesium and therefore without knowing whether this is really necessary.

The volumetric regeneration programmer:
A water softener with a volumetric programmer, for its part, takes into account the volume of water consumed and passed through the resin to carry out a regeneration. Thus, it regenerates when you have reached the setpoint volume, that is to say the maximum water volume that your softener can filter between two regenerations. The volumetric softener therefore adapts to your consumption and performs regeneration when this is really necessary. It is this type of softener which is the most used today.
