B Basic information
1 | Laws, regulations, standards
In the interest of good health, rules cannot be ignored when it
comes to the processing of drinking water (raw water). This
operation manual takes into consideration the current
regulations and stipulates information that you will need for the
safe operation of your water treatment system.
Among other things, the regulations stipulate that

only approved companies are permitted to make major
modifications to water supply facilities

and that tests, inspections and maintenance on installed
devices are to be performed at regular intervals.
2 | Water, scale, softening
The water works provide us with pure water (raw water) that is
suitable for drinking. However, this water is much more often
used for washing machines, heating systems, water heaters,
commercial devices, etc., where it can lead to problems if it is
"hard".
Hard water is generated if water containing carbon dioxide*
flows through layers of calcium. It dissolves the calcium until the
so-called calcium - carbon dioxide - equilibrium has been
reached.
If this equilibrium is unsettled (e.g. by heating

CO
2
escapes)
more calcium (CaCO
3
) is precipitated (scale).

Note : Calcium ions and magnesium ions exist side by side in
nature, e.g. in the mineral dolomite.
Hardness ranges according to the German Act on Environmental
Sustainability of Detergents and Cleaning Agents (WMRG):
The total hardness of the water is the sum of the concentrations
of calcium ions and magnesium ions.
From hardness range "medium" onwards, it is advisable to
soften the water for usage. Additional measures may be
necessary depending on the original quality of the water and its
intended use.
* CO
2
from the atmosphere is dissolved in water. In this process, a low
amount of carbon dioxide is generated.
Hardness range °dH °f mmol/l =

1 (soft) < 8.4 < 15.0 < 1.50
2 (medium) 8.4 ‐ 14.0 15.0 ‐ 25.0 1.50 ‐ 2.50
3 (hard) > 14.0 > 25.0 > 2.50
