Product Description

SS Multi-cartridge Self-cleaning Filter


 
automatic continuously on-line filtration, large filter area, compact design, optimized 
 
efficient impulse back-flushing, high dirt holding capacity, especially for high flowrate 
 
filtration and dirty water filtration
 
 
When the differential pressure crosses the pre-set limits. The backwash valve opens the 
 
system to atmosphere causing a high velocity reverse flow across the isolated section of 
 
screen. Dirt and debris are flushed out from this segment of the screen into the backwash 
 
arm and out of the strainer via the backwash piping.
 
During the backwashing cycle the main flow is uninterrupted and continues to be strained in 
 
the normal manner. The control system would automatically close the backwash valve after 
 
the screen is cleaned.
 
These units can also be operated manually from the control panel or in continuous backwash 
 
mode.

Application Fields


Power Plants : Treatment of Industrial Water for cooling generators and filtration of 
 
sealing water to increase the service life of the Turbine Shaft sliding-ring seals in 
 
Hydro-Electric Power Stations.
 
Steel Industry: Protection of nozzles and pumps during high-pressure descaling, water 
 
treatment for blast furnaces, rolling mills, cleaning, quenching applications.
 
Chemical Industry : Improvement of product quality by filtering process media. Filtration 
 
of White water, Black Liquor, Starch, Fuel oils, Caustic Solutions, Cooking oils, 
 
brackish/salt intake water etc. For filtration of water used for cooling, process, fire 
 
protection applications.
 
Pulp & Paper Industry : Removal of fibers from white water filtrate, Protection of spray 
 
nozzles for screens of paper making machines. This reduces frequent failures caused due to 
 
clogging and wear.
 
Mining: By filtering underground, spray water of even quality is assured. This results in 
 
more reliable operation of pumps and disc cutting machines
 
Environmental Technology. Used as pre-filters before waste water treatment plants, UV 
 
Treatment, Reverse Osmosis, membrane filtration etc.
 
Sewage Treatment Plants : During Production of industrial water, filtration of a take off 
 
of the clear run can be used to save valuable drinking or well water.
 
Heat Transfer / Heat Supply : Protects heat Exchangers from clogging & wear




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.
