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 deferrisation 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 | Intended use/field of application
The GENO-mat FE-Z deferrisation systems are used for the oxida-
tion of dissolved iron in the raw water. The systems are used for pri-
vate water supply plants up to maximum values of 3.0 mg/l of iron. If
the systems are applied and operated according to the instructions,
pure water values with a concentration of less than 0.1 mg/l of iron
can be obtained.
The following requirements must be observed in order to obtain op-
timum results:
 Hydrogen sulphide and oil may not be detected in the water to be
deferrised.
 Organic compounds should preferably not be contained in the
water; however, the maximum allowable value is 4 to 5 mg/l
above the COD.
 The oxygen concentration should be proportionally 15 % of the
existing iron concentration and the pH value must be higher than
7.0.
 However, should ammonium (> 0.1 mg/l) be detected in the raw
water, an additional treatment step is required.
 Should humic acids be contained in the well water, the pure wa-
ter quality to be expected might be affected.

3 | Function
The GENO-mat FE-Z deferrisation systems for the removal of iron
work with an active insoluble catalytic filter material. A central control
valve automatically controls the operating cycle’s filtration, backwash
and first filtrate.
3.1 Filters The raw water enters the exchanger tank via the raw water inlet and
flows through the catalytic filter material from top to bottom. Thus the
reaction of the oxygen with the iron contained in the water is accel-
erated.
Bivalent iron is transformed into insoluble, filterable, trivalent iron
(adding air sparingly might be required in order to improve the oxida-
tion process). The filtered pure water is then directed via the lower
distributing nozzle and the rising pipe through the pure water outlet
into the piping system.
3.2 Backwashing During the backwash process, the filter bed is forcibly flushed from
bottom to top and thus loosened up. Impurities retained during the
filtration process are washed out via the drain outlet at the control
valve. The GENO-mat FE-Z deferrisation system must be back-
washed every 6 days at the latest (for the setting refer to chapter F).
3.3 First filtrate By an automatic switch-over of the central control valve, the filter
bed will forcibly be flushed from top to bottom. This first filtrate is
discharged to the drain and afterwards the deferrisation system is
ready for operation once again.
3.4 Regeneration/
disinfection
For operating and hygienic reasons, the deferrisation system must
be regenerated every 6 months with the special granulate GENO-
Spezialgranulat or GENO-oxi plus.
3.5 Control unit The GENO-mat FE-Z deferrisation systems are time-controlled via
an electrical timer.
In order to properly use the automatic timer control, the time interval
between two filter sequences (backwash interval in days) must be
set.

1.1 Water installation When installing the GENO-mat FE-Z deferrisation system, certain
rules must be strictly complied with. Additional recommendations are
given in order to facilitate the handling of the systems. The installa-
tion information described below is also illustrated in fig. D-2.
Binding rules
The installation of the GENO-mat FE-Z deferrisation system repre-
sents a major interference with the drinking water system. Therefore,
only authorised experts may install such systems. In Germany, the
installation company must be registered in an installation directory of
a water company as per §12(2) AVBWasserV (German Ordinance
on General Conditions for the Supply of Water).
 Observe local and general installation guidelines.
 Provide a drain connection to discharge the backwash water.
 The installation room must have a floor drain (DN 100). If no floor
drain is available, a corresponding water stop device has to be in-
stalled.
 Observe the flow direction!
Recommendations
 Provide a sampling valve and a pressure gauge directly upstream
and downstream of the GENO-mat FE-Z deferrisation system (0 -
10 bar). This simplifies the sampling for the regular determination
of the iron concentration (functional check).
1.2 Electrical
installation
A shock-proof plug is adequate for the electrical connection. Howev-
er, it must comply with the specifications given in table D-1, may not
be further than 1.20m away from the GENO-mat FE-Z deferrisation
system and must carry constant voltage (do not couple with light
switch)!

Fill with filter material
1. Fill filter tank up to 50 % with water.
2. Check whether the rising pipe is covered by a protective cap, plug
on the protective cap, if necessary. The protective cap prevents
material from entering the rising pipe.
3. Centre the filter tank in the rising pipe.
4. Centre the rising pipe in the filter tank. Use the funnel supplied
with the system (refer to figure). Refer to Table D-2 for fill volumes.
Remove protective cap,
secure control valve
5. Fill up the filter tank with water
6. Centre the rising pipe properly and exactly.
7. Clean the filter tank’s screw thread and the sealing surface for the
connection of the control valve from any filter material that might be
clinging to them.
8. Remove the protective cap from the rising pipe.
9. Put the control valve from above onto the rising pipe and fasten it
by turning it to the right.
