The crystal quartz sand filter should be operated
independently of and parallel to actual spray foun-
tain and circulation technology. The filter can work
during fountain operation, in periods when the
fountain is not operating, or it can even work around
the clock.
The filter system consists of a container made of
fibre-glass reinforced plastic and a pump and a
multi-port valve. Everything is compact and pre-
mounted on a plastic pallet. The fill opening of the
filter tank is sealed with a cover and an integrated
manometer. The tank can be filled with crystal
quartz sand or AFM filter medium and contaminat-
ed water is suctioned in by the pump. In the filter
the water is forced through the filter material via an
upper distributor with sieve and then it is fed back
into the pool through a lower distributor with small
open-seam pipe. If the filter capacity is exhausted
the filter is simply rinsed in reverse and the debris
is discharged via the wastewater channel.
