Water Softener - Conti CC100 Notice Technique

20.6. WATER SOFTENER

When the mains water has a high hardness (>10°TH ou >4 °KH), it is recommanded:
o To use a water treatment
o To regenarate regularly the filters.
What is the total Hardness of the water ?
o This is the amount of calcium and magnesium ions in the water.
o These ions are partly responsible for limestone formation.
o It is measured with the test strip provided with the machine.
o The unit of measurement is the ° French (° TH) or the ° German (° dH).
What is the Karbonat Hardness of the water ?
o This is the amount of Carbonate Calcium ions and Carbonate Magnesium ions in the
water.
o These ions are completely responsible for limestone formation.
o It is measured with chemical dropper testers.
o The unit of measurment is ° Carbonate (°KH)
There are 2 types of water treatments:
Salt water softeners
o They treat the total water hardness (°TH)
o By an exchange of sodium ions with calcium and magnesium ions.
o They require periodic regeneration of the resins by the user.
o To use when the water hardness is > à 10°TH ou > 5 °GH
Resins filters :
o They treat the Carbonat hardness water (°KH)
o By fixing carbonate ions on the resins.
o Often fitted with microfiltration and carbon filtration.
o To use when the Carbonat Hardness is > à 6°KH
o Highly recommended by the manufacturer :
