Fast rinse
Hard water flows from top to bottom through the ion exchange resin, driving out the excess residues
of brining process. Effluent goes to drain.
Brine tank fill
After brining and rinsing, water is fed to the brine tank, via the brine draw line, filling it again up to
the normal water working level, this is to ensure that concentrated brine available for the next
regeneration process.
The softener is returned to service!
1.3 Water pressure
In order to guarantee optimum and economic operation of the system, the water pressure should be
adjusted to between 2.0 bar and 8.0 bar.
The water pressure should not fall below 2.0 bar, in order not to impair the functional performance of
the softener.
Regular maintenance avoids the increase of pressure loss and guarantees correct system
operation.
The water pressure must not exceed 8 bar, doing so may pose a safety risk and cause operational
problems, it is recommended that a pressure reducing valve be fitted upstream of the water
softener.
Caution!
Pressure booster systems must not be installed in flow direction directly after a water treatment
system into the piping.
In case a pressure booster system is required for the transport to the consumer the system shall
only transport soft water into a pressure-less vessel which is used for the subsequent pressure
booster system.
