Answer to Question #226958 in Chemical Engineering for Lokika

Question

Classify the filters based on driving force....

Answer 1

The driving force to overcome the frictional resistance encountered by the water flowing through filter can be either the force of gravity, or the applied pressure force.

As such on the basis of the driving force the fillers arc classified as: (i) Gravity filters; and (ii) Pressure filters.

The gravity filters are further classified as: (a) Slow sand filters; and (b) Rapid sand filters.
