Water Filtration Solutions

A moment after the following solenoid
introduces the air in the filtered water
deposit and inside the filtering element.
This mixture of water –air provokes a
hydraulic –pneumatic force which is
used to overcome the pressure made
by the spring over the stack of discs,
generating the decompression of the
same due to the rising of the piston.
The release of discs makes possible these can freely spin due to
the tangential projection of the water coming from the feeder bars
which at the same time are used as structural support of the stack
of discs.
The correct distribution of the holes in the bars, together with the
studied design of the same, project water under pressure which
tangentially falls into the discs, generating its rotation and vibration
of the same and consequentially the complete elimination of the
retained solids through the backflushing valve. These are carried to
the outside by the drainage manifold.
Once the station has completed the backflushing process, it is
repeated sequentially until it completes the totality of stations which
form the filtration equipment.
The end of the backflushing coincides with the closure of the
drainage outlet and the opening of the inlet manifold on the last
station which forms the filtration equipment. In this way the filtration
initial conditions are re-established and also the availability of the
totality of filters to carry out the filtration function.
All that available hydraulic power is used to overcome the
pressure exerted by the spring on the discs stack generating in
this way its own decompression due to the piston displacement
(raising).
