2 Function
2.1 Ion exchange
When the water passes the filter, calcium and
magnesium ions is absorbed by the ion
exchange mass while the corresponding
amount of sodium ions is carried to the water.
This procedure is called ion exchange (in this
case softening).
2.2 Regeneration
When the ion exchange mass is saturated
with calcium and magnesium, it must be
treated so it can soften the water again. This
treatment is called regeneration.
Regeneration begins by adding the diluted
salt solution (brine) with regulated flow to
achieve even distribution and sufficient
contact time in the ion exchange mass.
Calcium and magnesium are consequently
released and rinsed to drain while the ion
exchange mass is again saturated with
sodium.
Once the salt solution is introduced, the
regeneration continues with the first rinse,
which displaces the salt solution through the
ion exchanger.
The regeneration ends with a second flush
that is controlled by the conductivity of the
wastewater.
After 2nd flush, the filter is automatically
switched on for operation.
3 Installation
a. Place the unit on a flat surface, with
the salt container on the side.
b. Connect the top and bottom pipes to
the tanks and the valve rack.
c. Fill both tanks half with water before
filling them with ion exchange
resin.(see chap. 4.1)
d. Connect the inlet to the raw water
supply and the outlet for consumption
– the flange connections is DN50 for
HVD 400, 600, 900 and DN100 for
HVD 1200/1550. Be aware, that the
connected pipes shall be relieved.
e. Connect the waste water
– flange size
DN40
f. The dynamical pressure shall be at
min. 3 bar and max 10 bar.
g. Connect the unit to power supply 230
V AC.
4 Commissioning
Please note that during operation of the
filters, ensure that no ion exchange is flushed
