  • Pressure Sand Filter Calculator | WE

    Calculation for pressure filter design. Pressure sand filter is the first unit process in any treatment. It is used to remove suspended solids from raw water. Filter is designed based on velocity consideration. Recommended velocity for filtration is 10 m/hr to 30 m/hr. If we select velocity less than 10 m/hr, channeling will happen and velocity

    Sand Filter Design Slow sand filtration is a simple and effective technique for purifying surface water. It will remove practically all the turbidity from water, together with virtually all harmful eggs, protozoa, bacteria and viruses without the addition of chemicals and may frequently be constructed largely with local materials.

    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. The coarser sand in
