3.5 Functional description
3.5.1 Filtration
In combination with desaliQ inline filter module:
The unfiltered heating water flows from the bottom through the inlet side of the cartridge and
via the flow distributor. Then, the water containing the particles passes the magnetic rod.
Magnetic particles such as iron particles/magnetite, etc. are attracted and removed from the
heating water.
The pre-cleaned water then flows through 6 filter elements with a pore size of 5 µm.
By using the strap, the filter module can be easily removed from the mixed bed cartridge.

BA_TD3-GM001en_034_desaliQ_MB9-MB5.docx
3.5.2 Demineralisation
In combination with desaliQ resin bags:
Physical
Via an interior distribution system, 1 or 2 resin bags filled with mixed bed resin are steadily
flown through from bottom to top.
The fully demineralised water (demi water) is directed to the tank outlet via a collection ele-
ment located at the tank lid.
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 com-
ponents 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, phos-
phate, sulphate, chloride and hydrogen carbonate, are exchanged for OH-ions.
Full demineralisation removes almost all undesired components from the raw water. Thanks
to the highly alkaline anion exchanger resin, silicic acids and carbon dioxide are also filtered
off. The H+and OH-ions generated during the exchange process combine to H2O. This re-
sults in ultra-pure water.
Demineralisation of raw water
The main application of the desaliQ mixed bed cartridge is the full demineralisation of raw
water for easy and quick filling and make-up water feed of heating systems as well as full de-
mineralisation in the ongoing heating operation (max. 4 bar, 65 °C). The raw water is di-
rected to the inlet of the mixed bed cartridge via an optional system separator and a fine fil-
ter.

5 Installation
CAUTION
Risk of contaminated drinking water if there is no system separator pre-
sent.
●The mixed bed cartridges are not intrinsically safe. If the mixed bed cartridges
are installed without a fitting and there is no system separator downstream of the
water connection to the house, then there is a risk of the drinking water becoming
contaminated.
►Install a system separator upstream of the mixed bed cartridge.
