Calculate Pressure Drop in Filters and Strainers ...

Total Pressure drop (P1) = 0.9 X 1.2 = 1.08 psi Multiply P1 by the specific gravity of the fluid actually flowing through the strainer to get P2. Since specific gravity = 1 Pressure drop (P2) = P1 X Sp. Gravity = 1.08 X 1 =1.08psi Using chart 2 multiply P2 by the appropriate component factor (CF) to get P3. Using chart 2, (P3) = P2 X (CF) = 1.08 X 0.35

Several curves of pressure versus depth through a sand filter are shown in the figure below, each corresponding to a different time during the filter run. The hydraulic (pressure) head at the top of the sand (indicated in the figure as depth = 0 m) is 4.0 m at all times. The filter bed is 2.0 m deep and must be backwashed when particles start breaking through into the effluent, or when the headloss exceeds 2.2 m. The filter …

Pressure drop on sand filter | Trouble Free Pool

20/10/2015· All the skimmers seem to have good circulation. When turning off the main drain pressure drops further as it should. I've always had a problem with the pressure running too high in my opinion at about 26 psi after a backwash. I would wait for it to get up to no more than 35 psi before backwashing again and it would always go down to about 26-27 psi. Now it is running at 20 psi which is more in the …

Water Handbook - Filtration | SUEZ

Pressure filters are typically used with hot process softeners to permit high-temperature operation and to prevent heat loss. The use of pressure filters eliminates the need for repumping of filtered water. Pressure filters are similar to gravity filters in that they include filter media, supporting bed, underdrain system, and control device; however, the filter shell has no wash water troughs ...
