Filter Sand . The filter sand used in rapid sand filters is manufactured specifically for the purpose of water filtration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration.

Pressure filters require finer grades of sand, grade 22/36 being the finest grade used. The pressure filter height should be less than 5 m. When used in downflow, design loadings and limitations are the same as RGFs, but the vessel (especially if vertical) should not exceed 3 m in diameter, to avoid flow distribution problems.
