12.1 Explanation of terminology
Capacity
Describes the amount of fully softened water that the water
softener can produce in its entirety or in any part of it.
Regeneration water After the regeneration, this water is saturated with calcium
ions and is flushed out of the system into the drain.
Raw water Raw water is the untreated water before it passes through
the filter.
Stagnation Inadequate water flow without pressure to force the water. In
dead-end pipes and in cross-connections, also in pipes that
are not being used such as during holidays.
Period of inactivity Time in which a system filled with raw water is available
without power supply and without removal of water.
Drinking water Drinking water is any water that is intended for use in the
domestic environment for drinking and all other food
preparation purposes, for personal hygiene and cleaning as
well as for cleaning objects that do not only temporarily
come into contact with foodstuffs or the human body.
Turbine water meter
A turbine (Woltmann) fitted in the system which transmits
pulses to a sensor by means of a magnet, thereby allowing
the flow rate through the system to be measured.
Fully softened water Water with a residual hardness of 0 °dH.
Soft water Soft water is the general term for softened water, and is also
referred to as softened or decalcified water.
12.2 Soft water with blending
CAUTION: Blocking of reverse osmosis systems by blended raw water.
● The functionality of osmosis systems is endangered.
► If the water softener is installed before a reverse osmosis system, the feed line to
the reverse osmosis system is not allowed to be configured as soft water with
blending.
For the soft water hardness, see the example calculation for the sodium content in the water
(refer to chapter 12.3).
