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 infor-
mation that you will need for the safe operation of your water treat-
ment system.
Among other things, the regulations stipulate that
only approved companies are permitted to make major modifica-
tions to water supply facilities
and that tests, inspections and maintenance on installed devices
are to be performed at regular intervals.
2 | Water, scale and 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).
