20-500 micron15-900T/H Water Filter for Chilling water treating
How water filter 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 pressuredrop reaches 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, whichaggressively sucks the dirt off the screen, similar to a vacuum cleaner, and are carried tothe drain via the rinse valve. The dirt collector rotates, ensuring the entire screen is cleanedeach cycle. The process takes a matter of seconds, without interruption of system flow.
Filter has differential switch and integrator. Once the pressure drop reaches a preset level, a rinse cycle is activated by the PLC controller.

1,Chilling water treating: such like cooling tower, water supplement system, air conditioning system, heat exchange system.
2,Raw water treating: such like surface water, lake, sea water, tank water, well to remove grind, sand, algae, organism etc.
3,cycling industry water: cooling tower, polishing process water, ion exchange water, spraying process water, heat exchange plant, rolling plant, casting plant etc.
4,irrigation: farm, dip field, golf, lawn etc.

1.One check valve must be installed at filter outlet. Return pressure and back water is forbidden, in case of screen out of shape.
2.If system wok pressure over 0.8MPa, should install break valve at drain pipe to reduce impact to screen.
3.Notice motor rotating direction. Shut off power immediately once back rotating (anti-clock wise ) occurs. )
4.Installation each part according to arrow direction.
5.Sudden pressure relief at outlet pipe is forbidden. Take normal work pressure 1.3MPa for example, if suddenly open branch valve at outlet, it will occur instant huge different pressure, which damage screen.
6.Make sure filter used under correct work pressure, capacity.
7.If alarms, open by-pass valve for temporary back washing solutions.
8.Make sure control box have constant power supply. If power off, users can open by-pass valve, close in and outlet valve and control box switch.
