General Operating Principles

As the water enters into filter inlet 1, it is prefiltered through the coarse screen 3 to prevent large particles entry that will damage the fine screen and internal parts.

Then water passes into the second filtration section that contains multi-layer fine screen 4. This screen is protected by a robust coarse mesh that also provides a prefiltration. While water passes through the fine screen towards the outlet 2 the particles within the water accumulates on the inside surface of the fine screen and produce a dirt layer. The dirt layer itself will act as a filter and collect much smaller particles than the stainless steel screen. The differential pressure between pressure (DP). As the dirt layer builds up on the screen, and when it is thick enough to cause a certain differential pressure value the flush cycle is started.

At a preset value, back-flushcontrol unit 12 opens flushing discharge valve 9 and a strong back-flush stream that goes off to the atmosphere via drainage pipe 11 occurs. That flow creates a suction effect in front of the nozzles 6 and sweeps the dirt collected on the fine screen.

The dirty water sucked from the fine screen surface flows through the collector pipe 7 and the hydraulic turbine 8 and impels a rotary movement of the dirt collector while going off the drainage pipe. At the same time the drop of the pressure in the hydraulic turbine 5 and drainage of piston 10 force the dirt collector into an axial movement. This turning and axial movements together create a helical movement that enables the suction nozzles to sweep the entire screen area.

When backflushing is completed, a second flushing cycle is automatically triggered by pushing the collector assembly to its original position and the filter remains ready for the next flushing cycle. The combined flush cycle takes 10-60 seconds depending to the model. During backflushing the filtration process is not interrupted.

For models equipped with automatic self-cleaning coarse screen, the automatic valve which can be adjusted by timer opens automatically, and the dirt layer accumulated on the coarse screen is scraped off by hydraulic current and is discharged.
