Water softening system
The water softening system (ion exchanger) is a container which is
filled with fine-grained synthetic resin granules. This synthetic resin
replaces calcium and magnesium ions in the water with sodium ions
which are on its surface.

3.11.1 Water softening
1
Synthetic resin
The untreated water with its hardness constituents is conveyed via the
synthetic resin. Calcium and magnesium are bonded to the surface of
the exchange compound while sodium ions are released into the
water. When all sodium ions have been replaced with ions of the hard-
ness constituents, the capacity of the water softening system is ex-
hausted and must be regenerated.
