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. This operation manual takes into
consideration the current regulations and stipulates information that
you will need for the safe operation of your demanganisation sys-
tem.
Among other things, the set of rules stipulates 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 | Designated application/area of application
The GENO-mat MN-Z demanganisation systems are designed for
the reduction of iron and/or manganese. They are used in the resi-
dential sector for private water supply plants with maximum values
of up to 3.0 mg/l of iron and 1.0 mg/l of manganese. If the systems
are operated properly and handled according to the operation man-
ual, pure water values as required by the German Drinking Water
Ordinance (TrinkwV) can be achieved.
For an optimum reduction of iron and manganese, a pH value > 7.2
is required. A dosing system for oxidants has to be provided up-
stream of the demanganisation system.
However, should ammonium (> 0.1 mg/l) be detected in the raw wa-
ter, an additional treatment step is required.
3 | Function
The demanganisation system GENO-mat MN-Z is operated with the
natural, catalytic filter material Fermanit. A central control valve auto-
matically controls the operating cycles filtration - backwash - and first
filtrate.
