3 Product description
The water softener is equipped with a control valve for the 3 exchangers, which are
controlled depending on the volume.
Regeneration is triggered when the next exchanger to be regenerated is exhausted or 50%
of the next but one exchanger to be regenerated is exhausted. The water softener
regenerates with raw water.
3.1 Intended use
The water softeners Delta-p/Delta-p-I have been developed for the continuous production of
softened and partially softened water and can be used in the following areas:
●Softening and partial softening of:
•Well water
•Process water
•Boiler feed water
•Cooling water
•Air-conditioning water
•cold drinking water
•industrial water

3.3 Functional description
3.3.1 Ion exchange process
The water softener works according to the ion exchange principle. The exchange of calcium
and magnesium ions for sodium ions causes the water to become soft.
Figure
Explanation
The exchanger contains ion exchanger resin in the form of small resin
beads.
Sodium ions adhere to each resin bead.
Hard water containing lots of calcium and magnesium ions flows through
the exchanger.
The ion exchanger resin absorbs calcium and magnesium ions from the
water in exchange for sodium ions.
This reaction is called ion exchange.
The calcium and magnesium ions are retained in the exchanger.
Soft water without calcium and magnesium ions, but containing sodium
ions, leaves the exchanger.
This process continues until no more sodium ions are available. The ion
exchanger resin is exhausted.
The exchange can be reversed if a large amount of sodium ions is
added.
The exchanger is rinsed with brine (water containing salt).
By their sheer number, sodium ions displace calcium and magnesium
ions on the ion exchanger resin.
This water containing calcium and magnesium ions is discharged to the
drain.
The initial state is restored.
The ion exchanger resin is regenerated, and thus ready for operation.
Sodium ion Calcium ion Magnesium ion

4 Control unit
The water softeners Delta-p/Delta-p-I are quantity and/or time-controlled. They are operated
and monitored by means of the control unit GENO-IONO-matic3. The operating and
regeneration operations are automatically controlled depending on the selected operating
mode, water consumption, daily interval and time.
The controller has the following contacts for communication with interfaces provided by the
customer:
●Programmable input
●programmable output
●Input for accessory "pre-alarm salt supply"
4.1 Operating principle
In the control unit, the different parameters for the different system types are stored in data
records.
The operating data (step times, capacity figure, operating mode, monitoring times, special
functions) are stored in the respective data record, so that the system is ready for operation
after the data record has been selected.
4.2 Definition of the operating states
The following definitions apply to the exchangers (AT):
Definition
Explanation
Exchanger*
Is in operation and usually has the lower remaining capacity.
It will be exhausted next and is the next for regeneration.
Exchanger**
Is in operation and usually has the higher remaining capacity.
It will be exhausted next but one and is the next but one for
regeneration.
Exchanger***
Is already regenerated (standby)."
