Diatomatic filters

Filtrating elements
Operating phases:

Phase 1: Filtration

• suspended impurities (1) in the water are stopped by the filtrating surface
• operating recirculation pump; the filtrating layer is created
• the filtrating layer is created by the diatomite (2), attached to the bended cloth (3): this bending, due to the dynamic pressure of the fluid, has the ballast come up (4).
• the filtrating surface tends to clog.

Phase 2: Unclogging

• automatic stop of the recirculation pump
• dynamic pressure of the fluid no longer occurs
• the ballast comes back down and the cloth stops bending
• the impurities and the surrounding filtrating layer falls at the bottom of the tank
• remains on the residual layer (5) do not require recirculation on the filter

Phase 3: Filtration

• recirculation pumps are back in operation
• reconstruction of the filtrating layer, where the impurities and the diatomites hold on to the residual layer
• the filtrating layer is free and ready to stop new impurities until the next unclogging phase; suspended impurities (1) in the water are stopped by the filtrating surface

Phase 4: Unclogging

• automatic stop of the recirculation pump (usually every three hours)
• dynamic pressure of the fluid no longer occurs, etc.
