CLEANING PROCESS

The pressure differential is manually monitored via the inlet and outlet manometers. An increase in pressure indicates the need for cleaning. To begin, shut off the water supply and depressurize the system. Then, remove the cover and extract the filter cartridge.

The cleaning method depends on the filter type. A screen filter element is cleaned directly with pressurized water. For a disc filter, the cartridge's retaining screw must be loosened to separate the discs for a thorough cleaning with pressurized water. After cleaning, the filter is reassembled and ready for service.

WORKING PRINCIPLE

Water enters the filter and passes through the filtration element (either a fine screen or a set of discs). During operation,

contaminants gradually accumulate on the surface of this element-the inner surface for screens or the outer surface for discs. This buildup obstructs the water flow, creating a pressure differential between the filter's inlet and outlet. Manual cleaning is required when this pressure differential reaches 0.7 bar.
