5.6 Function description
5.6.1 Method of operation
The filter containers are filled with ion-ex-
change resin. This comprises small plastic
resin balls on which the calcium ions, which
make the water “hard”, are exchanged for
sodium ions. This makes the water “soft”. In
the control head an adjustable quantity of
not-softened raw water is admixed to obtain
the mixing water hardness downstream of
the system. However the ion-exchange res-
in only absorbs a limited quantity of these
hardness components. Dependent on the
water hardness and the treated water vol-
ume, sooner or later it is exhausted. The
time at which it becomes exhausted is
measured with the water meter and regener-
ation automatically triggered. To do so, dilut-
ed brine (sodium chloride) is used to remove
the hardness components from the resin.
5.6.2 System design
The water softening system is designed as a
parallel system that is regenerated in two
stages. During regeneration, the two resin
containers are alternately responsible for
soft water provision. In this way soft water is
always available for the consumer, even
during regeneration.
5.6.3 Regeneration
With a very short regeneration period of
about 7.5 minutes per resin container (total:
15 minutes) high volume continuous draw-
ing is possible.
The soft water volume is precisely meas-
ured using a water meter in the system’s soft
water pipe and in this way triggering of re-
generation is controlled. Regeneration is
performed according to DIN EN 14743 and
DIN 19636-100 using miser salting. Disin-
fection of the system takes place at regular
intervals to prevent microbe contamination.
The small quantity of chlorine required for
this is created electrolytically during regen-
eration from the absorbed brine.
5.6.4 Control of regeneration
Regeneration is performed automatically via
wear-free ceramic disc valves. The regener-
ation sequence is fixed by the geometry of
the discs and therefore need not be re-en-
tered after a power failure.
5.6.5 Overflow valve
If the drawing of water (e.g. by a flushing
valve) is very strong, an overflow valve inte-
grated in the control head opens so that
hard water can bypass the system to limit
the pressure loss. This means that the mix-
ing water hardness temporarily increases in
the pipe downstream of the water softening
system.
