Product Description

Multi-cartridge Backwash Water Filter For Chemical Industry


Full series of filter adopts line gap or super weaving stainless filter elements, filtering accuracy is from 25 to 3000 microns, which ensure high filtering rate of polluted particle in the process medium. When the filter monitors filter is fouling, it will Start online selfcleaning operation, which will not affect the continuity of the liquid flow in filter outlet during this cleaning.






Chracteristics of SS multi-cartridge automatic backwash filter
 
a.it is usually used in large flow rate water with high filtration degree ,such as 50-100 micros.
b.there will be 5 to 20 or more pcs SS filter cartridges inside the filter.
c.after one day working,all filter cartridges will be backwashed by setted parameters or pressure control.
the particles which intercepted and accumulated on cartridge will be washed away.
during backwash processing,drain valve will open and particles will be outfall .
for example,backwash time for each cartdiegs will last 10 to 20 seconds.
if there are 10 pcs of SS cartridge ,backwash time will be 220  to 240 seconds.
d. after backwash,the filter will come to next filter period(usually it is 24 hours).
e.you could set the backwash circle as per practical requirement,such as twice or 3 times every 24 hours.
 



Working procedures:
Backwashing water filters are large tank-style filters that get their name from the fact that they clean and renew themselves by backwashing. Backwashing consists of reversing the flow of water so that it enters from the bottom of the filter bed, lifts and rinses the bed, then exits through the top of the filter tank.
The filter bed itself is a granular substance that is usually referred to as the filter medium. Media (media is plural, medium is singular) are numerous and varied. Common media are granular carbon, sand, garnet, anthracite, zeolite, granular manganese dioxide, and greensand.
 
The unfiltered water enters from the left and is routed by the control valve into the filter tank. The water then filters slowly through the medium until it reaches the bottom of the tank where it is collected through a specially-designed sieved "basket" at the bottom of the center tube seen in the picture. The filtered water then passes up through the center tube, called a "riser" or a "dip tube," passes through the control valve, and exits the right side of the filter.


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