Sand Filter designpdf Filtration Water Purification

The pressure sand filter is essentially a rapid sand filter placed inside a pressurized chamber while the diatomaceous earth filter is not commonly used in treatment of drinking water History The history of water treatment dates back to approximately the thirteenth century BC in Egypt we will design a rapid sand filter and a clear well The working principle of a Pressure Sand filter is very straight forward In a Pressure sand filter, water is gone through multi layers of filter media comprising reviewed sand, rocks and rock layers The contaminants in the water are caught in the media bed and sifted water goes into the release manifold at the base of the tanksPressure Sand Filter, Pressure Sand Filter Manufacturer The pressure filter is operated at elevated pressures, thus prolonging the filter cycle and/or increasing the rate of flow of water through the filter Gravity filters are commonly operated at 2 GPM/sq ft *, whereas pressure filters are operated at 3 GPM/sq ft and higher The rapid sand filter is operated with clarification ahead of the filterSand Filter an overview ScienceDirect Topics USA Sand Filter Design Inputs Design a rapid sand filter to treat Q= 20000 m3/d Allowing filtered water for backwashing: QBW= 2% Time used for bakwashing per day = tBW= 050 hours Assume the rate of filtration = 10 m/h Number of Filters 200 Length/ Width of Filters= 130 Depth of Sand Media= 100 mFILTER DESIGN EXAMPLE See Design Criteria Filters Typically, the volume within the practice can be less than the total water quality volume for filter designs Step 9 Compute volume within practice: Volume within filter bed (V f): V f = A f (d f) (n); n = 04 for sand (Porosity) V f = (473 sq ft) (15') (04) = 284 cubic feetSand Filter Design Example
