The filter sand used in rapid sand filters is prepared from stock sand specifically for the purpose. Most rapid sand filters contain 60 to 75 cm thickness of sand, but some newer filters are deeper. The sand used as filter media in RSF is generally of effective size of 0.4 to 0.7 mm and uniformity coefficient of 1.3 to 1.7.Web

Cartridges have a porous membrane that water can flow through. The fabric is what catches particles and debris. These catch much smaller particles than sand filters do in the 10-15 micron range. The membranes in cartridge filters wear out much faster than sand does, so they have to be replaced every 1-3 years.Web
