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). Having
passed through the backwash protective
filter, the flow is redirected upwards and
flows through a concentrically arranged noz-
zle system (2). This nozzle system brings
about an activation chamber in which the
pressure drops considerably in certain
zones, what causes a partial out-gasing of
the carbonic acid, that is dissolved in the
water.
