Best Commercial Automatic Self Cleaning Screen Water Filter

                    Best Commercial Automatic Self Cleaning Screen Water Filter

How It Works
The unit consists of two stages of filtration, a coarse pre-filter and
a stainless steel fine screen.The unwanted solids accumulate on the inner surface of the fine screen, building up a filtercake,which filters out even finer particles, creating a pressure differential. Once the pressuredropreaches a preset level,a rinse cycle is activated by the factory supplied control system.

The solids are removed from the fine screen using a spot backwashing method, whichaggressivelysucks the dirt off the screen, similar to a vacuum cleaner, and are carried tothe drain via the rinsenvalve. The dirt collector rotates, ensuring the entire screen is cleanedeach cycle. The process takesa matter of seconds, without interruption of system flow.    

Control method
Filter has differential switch and integrator. Once the pressure drop reaches a preset level, a rinse cycle is activated by the PLC controller.

 Application 
1,Chilling water treating: such like cooling tower, water supplement system, air conditioningsystem, heat exchange system.
2,Raw water treating: such like surface water, lake, sea water, tank water, well to removegrind, sand, algae, organism etc.
3,Cycling industry water: cooling tower, polishing process water, ion exchange water, sprayingprocess water, heat exchange plant, rolling plant, casting plant etc.
4,Irrigation: farm, dip field, golf, lawn etc.
5,Recycle water

1,Keep space for filter install and maintenance.
2,Drainage pipe length not longer than 20m. Avoid more turns off, keep outlet pipe parallel with ground.

Testing 
1,Close inlet outlet valve before testing. Open by-pass valve. Wash dirties staying in pipes.
2,Open inlet valve gradually. Let water into filter till air comes out from filter house.
3,Check leak at joint part, check in/outlet pressure gauge. Connect power when comes to system pressure.
4,Set up drainage time based on system pressure data.
5,Open outlet valve gradually if testing is normal. Close by-pass valve back to normal filtering.
6,Observe several differential pressure changes and drainage. Finish testing if normal.

Notice in using
Equipment can through into operation directly, as already has trial testing. Users can adjust settings based on actual use. Change relay's program and parameter is forbidden.

1st operation notice
Follow below steps in 1st operation
Check drainage pipe connection. No up-inclined angle.
Check connection tighten or not.
Check control box in a dry environment.
Connect power cord, green light means normal. Make sure electrical parts is dry. Water is forbidden into control box.
