CLEANING PROCESS

The cleaning process is triggered either by elapsed time or a differential pressure threshold. Differential pressure results from particle accumulation on the screen surface, which restricts water flow. This pressure difference-on undesirable condition-is resolved by the cleaning cycle. The filter is programmed to automatically start the cleaning process once the user-defined differential pressure value (recommended at 0.5 bar) is reached, thereby restoring normal operation. When the drain valve opens, a strong vacuum effect is created inside the filter, drawing debris from the screen surface. This suction helps the nozzles effectively remove particles from the screen and discharge them from the system. once the process is complete, the cleaning collector automatically returns to its original position, and normal filtration resumes, During backwashing, the filtering process continues. To ensure efficient operation, the inlet pressure should not be less than 2 bar (29 psi) during backwashing.

WORKING PRINCIPLE

Water enters through the inlet line and flows toward the outlet line of the filter. It first passes through a coarse screen for preliminary filtration, followed by a fine screen where particles are retained on its surface.During the cleaning process, accumulated contaminants are discharged through the drain line. The handle kit creates both linear and rotational motion, driving the cleaning collector. This allows the nozzles to scan the entire surface of the fine screen, suctioning particles that are then transported out through the collector. The combination of linear and rotational motion from the handle kit ensures complete coverage of the screen surfaces.
