HOW DO A SOFTENING WORK ?
The purpose of a softening is to reduce the lime in mains water to an reasonable level.
It is well-known that too much lime is harmful for water heating appliances, taps, shower heads, dishwashers, washing machines and water pipes
Soft water has another property: it washes better with less soap or washing liquid. When you take a shower or a bath, you use less shampoo or soap and your skin will have a soft touch.
A softening is environment friendly. Washing with soft water means using less soap and washing liquid. Hence you can avoid that dozens of kilos phosphate, washing liquids and others pollute our rivers.
Too soft water can possibly attack the metallic water pipes. That is why there is always a little lime in the softening. A little lime is also good for the health.
A softening is made of three pieces:
the softening : a holder through which the water flows. This holder contains yellow microballs, the ion switch resin. These balls can strip the lime and magnesium of the water.
the valve control , all the little valves electronically controlled that guide the water flow direction.
the brine bin (full of salt) : the valve control maintain a certain level of salt in the bin. The salt dissolves in this water for a concentration of 25% and forms brine.
The salt bin of a household softening can contain from 25 to 100 kg salt. A dishwasher only 1 to 1,2 kg. Once the concentration of 25% salt in the water reached, the salt does not dissolve anymore and the remaining salt remains granular.
