Operation in filtration

1- the liquid to be filtered enters through an inlet into a first chamber
2- the liquid goes through little holes into a second chamber and forcedly goes through the filtering discs polyester tissue which filtrate it and direct it towards the outside of the disc itself.
3- the liquid, from the inside of the disc, is directed inside the shaft.
4- the liquid goes out perfectly filtrated.

The impurities stored on the filtering discs walls create a layer which causes the pressure difference between the inlet liquid and the outlet liquid. The value is found on the differential pressure manometer or on the manometers placed in the inlet/outlet of the circuit.
