Product details
Model Number: 3"unit Exogenous Filtration System Brand Name: Duoling Key Specifications/Special Features: Brand name: DuolingModel number: water filterVoltage: 220VPower: 200WWeight: 185kgCertification: ISO 9001:2008Warranty: one yearUsage: liquid filterMaterial: plasticSize: 3” compact, 3", 3” superAccuracy: 5-800umOEM: accepted
Manufacturer: yes
Auto backwash: yes

Constant filtering efficiency: as core element of filter, the uniformity of groove style filtering superposition piece reaches to international first rate standard
Filter is in effect for all kinds of suspension impurity including inorganic and organic impurity
High efficiency backwash, energy and water saving
Unit of backwash will be finished for 7-20 seconds only
In general the amount of consumed water in backwash is less than 0.5% of amount of filtering water for viscosity impurity, high effective washing also be reached
Suitable scope is wider
Full automatic control, flow continuously: filtering and backwash may be carried out at the same time
Loss of pressure and flow rate produced by automatic maintenance of system is less
Backwash is carried out in turn one by one and the others work normally
Reliable and long service lifespan system: the system has been identified through IS9002 international quality system and all the products are tested overall before sold
Almost without daily maintenance, installation and convenient operation, reliability transportation
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 trapped 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 the 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
