Multimedia (sand) Filtration Calculation - Lenntech

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.
