3.5 Functional description
3.5.1 Physical
The water softeners Delta-p are equipped with a central control valve for the three
exchangers and are controlled depending on the quantity.
Regeneration is triggered when the next exchanger to be regenerated is exhausted or 50%
of the next but one exchanger to be regenerated is exhausted.
The water softener regenerates with raw water.
3.5.2 Chemical
The exchanger contains ion exchanger resin in the form of small resin beads. Sodium ions
adhere to each resin bead. Hard water with a large proportion of calcium and magnesium
ions flows through the exchanger.
The ion exchanger resin absorbs calcium and magnesium ions from the water in exchange
for sodium ions. This reaction is called ion exchange. The calcium and magnesium ions are
retained in the exchanger. Soft water without calcium and magnesium ions, but containing
sodium ions, leaves the exchanger.
This process continues until no more sodium ions are available. The ion exchanger resin is
exhausted.
The exchange can be reversed if a large amount of sodium ions is added.
The exchanger is rinsed with brine, water containing salt.
By their sheer number, sodium ions displace calcium and magnesium ions on the ion
exchanger resin. This water containing calcium and magnesium ions is discharged to the
drain. The initial condition is restored.
