Working principle 
     Liquid into the filter via the water inlet, Impurities is deposited on the stainless steel mesh, Filtered clean water from the outlet flow out, With the accumulation of impurities inside the cartridge, the filter cake formed in the surface of the cartridge, which leads to gradually pressure , drop increasing between the inlet and outlet ,it begin the automatic cleaning process, when the pressure reaches the default .
 
    The automatic self cleaning finished by rotating cleaning brush and switching the drain valve .open the drain valve is blocked so that a negative pressure within the cartridge, the cartridge attached to the inner wall of the filter cake was cleaning brush cleaning off the relationship because of negative pressure through the sewage discharge valve in this body. The cleaning process is within 60 seconds, the system continues to flow cleaning.

 
Application

Chracteristics of SS multi-cartridge Automatic Backwash Filter

automatic backwashing self-cleaning filter suitable for demanding environments, for different application requirements ,3500micron -50micron filter screens are available.with 8"-36" inlet/outlet diameter. The self-cleaning filtration is started by a differential pressure switch which is monitoring the pressure difference on the filter inlet and outlet.
Continuity water supply: very less cleaning water requirement ,just 1% of the out water.the flushing time is2-15 seconds, and the whole system is continuity water supply.
High filtration precision: the filtration precision can be up to 20 microns, with a variety of precision filter screens.
Large filtration area: the standard effective filtration area is larger 7 to 40 times than the entrance area.
Reliable cleaning: there are a variety of control modes, such as manual, pressure difference , time, setting and PLC program logic control .
Low-cost and simple installation: various structure forms, suitable for installation various of conditions.
Long service life: more than 10 years ; the filter screen is made of stainless steel, and if necessary, the filter screens of different specifications can easily be replaced.

Important parts for filtration system:
01. Carbon steel cycloner,
02. Stainless screen,
03. Butterfly valve
04. Sewage device, etc.
