Diatomatic filters
Filtrating elements Operating phases:
![](images/spacer.gif) 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.
![](images/spacer.gif) 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
![](images/spacer.gif) 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
![](images/spacer.gif) Phase 4: Unclogging
- automatic stop of the recirculation pump (usually every three hours)
- dynamic pressure of the fluid no longer occurs, etc.
