Deacidification system
TE-Z
Corresponding to its carbonate hardness, all water contains a cer-
tain amount of free carbon dioxide which is necessary to dissolve
the carbonate hardness present in the water. If there is more free
carbon dioxide contained in the water than necessary, the water is
characterised as tending to precipitate lime. This aggressive carbon-
ic acid prevents the formation of protective scale/rust layers in the
piping and is therefore removed by means of a deacidification filter.
At the same time that the acid is removed, minor impurities are also
removed by filtration.
We would like to point out explicitly that due to the limited amount of
filtration material available, only a partial deacidification can be
achieved.
We therefore recommend installing an EXADOS dosing unit down-
stream of the deacidification filter in order to add EXADOS-spezial.
In order to prevent the filter material from clogging and to flush out
impurities, it is necessary to backwash the filter. The backwash is
carried out from the bottom to the top, opposite to the regular direc-
tion of flow.
The Hydrolit-Ca deacidification material used is consumed based on
the hydration of the excess carbon dioxide. (Consumption per g of
converted CO
2
approx. 2.5 g).
It is therefore necessary to check the filling level from time to time
and to refill, if necessary. The system must be flushed through every
time it is refilled.
If an increased bacterial count is to be expected from the well water,
we recommend to have a disinfection performed at regular intervals
by our technical service.
