### Lesson 6: Filtration

Filtration. Filtration Math. Introduction. In this lesson, we will design a rapid sand filter and a clear well chamber. Once again, these calculations are similar to those used for flash mix, flocculation, and sedimentation basins. For the rapid sand filter, the most important dimension is the surface area.

### Rapid sand filtration Cropaia

Typical filtration rate for rapid sand filter is 5 m/h, compared to 0.15 m/h in slow sand filtration. The area required for sand filtration can be calculated using the following equation: A = Q/V. Where, A is the filter area in square meters m 2 Q – Inlet water flow rate in m 3 /h. V – filtration velocity in m/h.

### DESIGN OF RAPID GRAVITY FILTER USING C PROGRAMMING AND …

& 0183;& 32;.Normally the depth of sand varies from 60 to 90 cm .figure ii shows sand layer and gravel layer in a filter DESIGN STEPS FOR ESTIMATION OF SAND DEPTH : The depth of sand can be checked against break through of flocs through sand bed by calculating the minimum depth required by Hudson formula: Q*D3*H/L = Bi*29323 Q = filtration rate in m3/m2/h
