The document describes the self-cleaning process of a basket strainer filter. The filter elements filter water from the inside out, building up a filtration cake. When the pressure drop reaches 0.5 bar, automatic cleaning is triggered. Brushes revolve and flush debris through an exhaust valve in around 15 seconds, while flow continues. A control system monitors pressure and activates cleaning if filtration is not restored within 5 minutes.

Filtering Process :
The water flow through the cylindrical filter element inside-out,
creating minimum pressure loss. During accumulation of
filtration cake on inner surface of the screen,pressure loss is
R
created accordingly.
Cleaning Process :
When the pressure drop between the inlet and outlet of the
filter reached 0.5 bar,cleaning of the filtration cylinder is
operated automatically.This operation consists of opening an
exhaust valve located on the housing lid and starting the
electric motor which revolving brushes and flushed out
through the open exhaust valve.The cleaning duration is
er
around 15 seconds.The service flow of the filtered water is
continuous during the cleaning cycle.

Control System :
Matl - Carbon Steel Matl - Stainless Steel The differential pressure switch transmits an electric signal to
( Horizontal Type ) ( Horizontal Type ) the electric control board when the pressure differential across
the screen reached the pre-set value.The control board
activates the motor and opens the exhaust valve.If due to
t
some fault the pressure drop over the filter is not eliminated by
Technical Specifications cleaning,the interval between successive cleaning operations
is limited by control board to a minimum of 5 minutes.
