CLEANING PROCESS

Manual cleaning is required when the pressure differential, monitored via manometers, indicates the filter is clogged. The process begins by shutting down the system and depressurizing the filter. The cover is then removed, and the filter cartridge is extracted. The cleaning method depends on the filter type. A screen filter is cleaned by directly washing the screen with pressurized water. For a disc filter, the compression screw on the cartridge is loosened to separate the discs, allowing pressurized water to effectively clean their surfaces. After cleaning, the cartridge is reassembled and reinstalled, and the filter is returned to service.

WORKING PRINCIPLE

The filter operates by passing water through a filtration element, which can be either a fine screen or a stack of discs. During operation, contaminants accumulate on the surface of this element—the inner surface in the case of a screen, or the outer surface for discs. This buildup obstructs the flow, creating a pressure differential between the filter’s inlet and outlet. To ensure proper performance, the filter must be cleaned by the time the pressure difference reaches 0.7 bar.
