from top to bottom. The water is demineralised by way of ion
exchange.
The demineralised water passes the conductivity measuring cell
and flows into the heating system.
A non-return valve at the outlet of the treatment group prevents
the water from flowing back from the heating system.
3.4.2 Chemical
Mixed bed resins consist to one part of a highly acid cation
exchanger resin and to the other part of a highly alkaline anion
exchanger resin. In the mixed bed cartridges, these two
components are present in a completely mixed state.
The cation exchanger resin removes all positively charged ions,
the so-called cations, from the raw water. All cations contained
in the water, such as calcium, magnesium, sodium, are
exchanged for H
+
ions.
In the demineralisation process, the anion exchanger resin is
used to filter off the negatively charged ions, the so-called
anions. All anions contained in the water, such as nitrate,
phosphate, sulphate, chloride and hydrogen carbonate, are
exchanged for OH
- ions.
Full demineralisation removes almost all undesired components
from the inlet water. Thanks to the highly alkaline anion
exchanger resin, silicic acid and carbon dioxide are also filtered
off. The H
+
and OH
-
ions generated in the exchange process
combine to H
2
O. The result of full demineralisation is pure
water.
