Commissioning

Prior to the start-up (Initial start-up or start-
up effected upon maintenance works) do fill
the filter with water and ventilate the filter.
– In order to do so the filter, when having
been installed, is filled with water
through the opening of the upstream
positionned shut-off valve.
– The filter has now become system-
pressurized.
– The enclosed air has then immediately
to be let out of the filter to avoid device
damage through water hammers. The
ventilation of the filter is effected via a
backwash performance (see chapter:
"Discharge of the backwash water")
upon the backwashing and ventilation
having been effected, the filter is ready-
to-operate.

Functional description

Unfiltered water runs through the built-in
rotary flange (3) into the backwash protec-
tive filter. The water flows through the fine
filter outside-inside, dirt particles getting
stuck on the filter cloth of the fine filter. The
adherent contamination is externally visible
through a transparent filter hood (5). After
having passed through the backwash
protective filter, the water to be treated is
redirected upwards and flows through a
phosphate metering device (1). In the
process the drinking water is added small
amounts of solved food-grade polyphos-
phate (2). Thus the natural amount of

calcium and magnesium contained in
drinking water is stabilized. From this point
on no harmful lime deposits (e. g. found in
pipings or at heater rods) can develop in the
installation. Phosphate is a mineral that is
also added to various foods.
When stabilizing the water hardness with
polyphosphates the consumption of deter-
gents is substantially lower. Due to lower
water hardness a washing machine e. g.
needs respectively less detergent.
