Auto Multi-Cartridge Back Flush Industrial Water Filters

Auto Multi-Cartridge Back Flush Industrial Water Filters




Filtration
The multiple cartridge backwash system is a fully automated filter system that removes or collects suspended solids from a liquid process stream. This systems' high efficiency operation can improve product quality, maximize solids recovery and protect equipment, operators and the environment.

 
Cleaning Process 
MANUAL vs. AUTOMATIC
Use automatic systems for maximum waste reduction with unattended service. Cleaning is controlled by changes in differential pressure across the filter media. As solids build up on the media, the differential pressure increases. When it reaches a preset level, the filter system automatically starts to clean the media.Manual systems are available where attended service is desired.

 


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.
 

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