Working principle

The raw water flows from the inlet into the filter cartridge wall, and then was blocked in the filter tube wall from the inside out through the cartridge, impurities, clean filtered water outflow from the outlet when the cartridge wall impurities piled upmore, formed on the surface of the cartridge filter cake, and the cartridge inside and outside the gradual formation of a pressure differential when the pressure reaches the preset value of the pressure controller will start the backwash process.
Inverse washing arm rotation to one of the cartridge below the position of the motor driven, electronically controlled drain valve punch, and vent drain, backwash arm sucker and cartridge inner wall of the contact part of the formation of a relative pressure below the cartridge lateral liquid pressure negative pressure zone, thus forming attractive, attached to the cartridge inner wall of the cake is inhaled and discharged. The filter is the use of this liquid flow before net cylinder wall impurities removed to achieve a true sense of the backwash. Motor driven cycle of backwash arm backwash cartridge 11. In addition to the cartridge that is backwash, the other is still a normal filter, filter backwash of this device without stopping the machine
