Filtration
Water enters the filter through the "Inlet". The water then reaches the fine screen, which purifies the flow by separating smaller particles from the water. As more water flows through, impurities build up on the fine screen.
As impurities on the screen accumulate, a pressure imbalance is built up between the internal section of the fine screen and its external section.
Cleaning Process
When the difference in pressure reaches the preset value on the electronic control unit, a series of events is triggered while water continues to flow to the system units. The flushing valve opens, pressure is released from the hydraulic piston, and water flows outside. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered, and the dirt collector nozzles begin a suction process. The water flows through the hydraulic motor, which rotates the dirt collector around its axis. The pressure released from the piston and the high pressure inside the filter, cause linear movement of the dirt collector. The combination of the linear movement and rotation significantly cleans the whole internal screen surface. The flushing cycle takes 5 seconds. The flushing valve closes at the end of the cycle and the increased water pressure returns the system to its initial position. The filter is now ready for the next cycle, with clean and filtered water flowing through the "Outlet".
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.
