Automatic Backwash Filter

Control by sensing pressure difference, when the impurities gathered, once the pressure differential exceeds the set value (1 Bar), the control switch turns on to start cleaning axis.


Back flushing can be manual or automatic control.

Impurities flow out through backwashing arm to backwashing outlet.

Filtration accuracy:25~200 micron.

Solid content: < 200ppm.

Flow rate reach up to4500M3/H;

Advantages

Control by sensing pressure difference, when the impurities gathered, once the pressure differential exceeds the set value (1 Bar), the control switch turns on to start cleaning axis.
Back flushing can be manual or automatic control.
Impurities flow out through backwashing arm to backwashing outlet.
Filtration accuracy:25~200 micron.
Solid content: < 200ppm.
Flow rate reach up to4500M3/H;



Filter working principle

When liquid with impurities flows into the bottom of the filter casing, the liquid flow rate will slow down, and the liquid will flow upward in direction of 90 °. The impurities which is been filtered down will be stopped in the shell, and the cleaning fluid will constantly flow outside of isolation elements, then finally flowed out from the outlet.
Back flushing process is completed by the difference between pipeline pressure and atmospheric pressure . A hollow cleaning device extends the length of the whole element; it rotates slowly inside the filter, and then discharge impurities out from drain valve. The end face of cleaning device is very close to filter element, its opening and impurity collector is of the same height. The impurity collector is made up of circle round and vertical pipeline tubes. In the whole countercurrent washing cycle, the main fluid will not be stopped and filtration process is going on.


Typical applications

Automatic self-cleaning filter can be used in almost all industrial area,including water supply, water disgusting, and the smell of salt water system, used for cooling, processing, fire protection services and so on.This ensures the cycle of water resources and saves cost.
Processing industry: protection of heat exchanger, the valve and water spray nozzle, pump and valve.
Electric power industry: protection of heat exchangers, pipeline pumps,waste water recycling system, etc.
Pulp processing industry: Remove fiber from water and prevent clogging nozzle. In the process of circulation, separate bark and chip.
Sewage/waste and water: the secondary filter processing of sewage,filtering the effluent in step two, then provide clean water for plants.
Metal processing industry: Provide large clean water for quenching,derusting, furnace, etc.
