Working principle of filtration state:
Water to be treated comes from the inlet port into the surface of the disc cartridge
Since discs are tightly pressed by the spring on the top of the filter cartridge, with the water going through the outside into the inside of the disc cartridge, the impurity will be trap pad on the intersection of discs
After that the clean water comes out from inside of the filter to the outlet port
Working principle of backwash state:
When the pressure difference reaches the setting value or the system reaches the setting time, the system will automatically enter the backwash mode
PLC controls valve and changes the water flow direction
Backwash water comes from the outlet port, and closes the one-way diaphragm on the bottom of the disc cartridge
Then the backwash water can only go through from nozzle channels on the interior center of the cartridge
High pressure of the nozzle channels tightens the spring and loses discs, meanwhile the backwash water squirts out from the channel along the tangent direction of discs and rotates and separates discs evenly, taking the impurities away from the discs
After backwash state, water flow direction changes and discs are pressed again and the filter will enter filtration state
