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.
