These filters are called multi-media filters because they contain different layers of filtration media ordered in decreasing porosity. Multi-media water filters are able to trap and retain a far larger number of particles (generally down to 10-25 microns) than traditional sand filters before backwashing becomes necessary.

Design of a pressure sand filter: Designing of pressure sand filter involves several steps which include: 1. Design of filter units: a. Rate of filtration is assumed between 3000-5000 L/m 2.h. b. Quantity of filtered water required per hour. c. Filter area. d. Length to breadth ratio is taken to be 1:3. e.
