FILTER DESIGN EXAMPLEUSA - Rapid Sand Filter Design Inputs Design a rapid sand filter to treat Q= 20000 m3/d Allowing filtered water for backwashing: Q_BW= 2% Time used for bakwashing per day = t_BW= 0.50 hours Assume the rate of filtration = 10 m/h Number of Filters 2.00Sand Filter - an overview | ScienceDirect TopicsThe homogeneous sand filter has a 0.9–1 m deep bed and typically of 0.85–1.7 mm of sand (effective size 0.9 mm) placed on a 50 mm layer of 4–8 mm or 75 mm of 6.7–13.2 mm gravel. Homogeneous sand of effective size up to 1.3 mm has also been used.Filtration - MRWAA pressure sand filter is contained under pressure in a steel tank, which may be vertical or horizontal, depending on the space available. As with gravity filters, the media is usually sand or a combination of media, and filtration rates are similar to gravity filters.

For example, a 1 " strainer with a Cv factor of 8 will have a 4 psi pressure loss in a system with a 16 gpm flow rate: (16 ÷ 8) 2 = 4.Calculate Pressure Drop in Filters and Strainers - .Pressure drop (P2) = P1 X Sp. Gravity = 1.08 X 1 =1.08psi Using chart 2 multiply P2 by the appropriate component factor (CF) to get P3. Using chart 2, (P3) = P2 X (CF) = 1.08 X 0.35 = 0.38psi Let, P4 = P2 – P3 = 1.08 – 0.38 = 0.7psi Multiply P3 by the = 0.38Recalculate Filter Pressure Drops at Higher Airflows | .Finally, multiply the manufacturer's rated filter pressure drop of .13-in. w.c. at 1000 CFM times the squared increase in airflow ratio of 1.44 to find the pressure drop of the filter at 1200 CFM. By using fan law two, we know at 1200 CFM the filter pressure drop will increase from .13-in. w.c to .19-in. w.c., for a total increase in static pressure of .06-in. w.c.Sand Trap Louvre - TROX UKSand Trap Louvre Types WSL and AWSL for Building Façades 3/2.1/B/2 TROX UK Ltd Caxton Way Thetford Norfolk IP24 3SQ Telephone +44 (0) 1842 754545 2 Description · Materials · Fixing _____2 Construction · Dimensions · SelectionFILTER DESIGN EXAMPLEUSA - Rapid Sand Filter Design Inputs Design a rapid sand filter to treat Q= 20000 m3/d Allowing filtered water for backwashing: Q_BW= 2% Time used for bakwashing per day = t_BW= 0.50 hours Assume the rate of filtration = 10 m/h Number of Filters 2.00Selection of optimum filtration rates for sand filtersup in the sand layer resulting in an increasing pressure drop or head loss through the sand layer.
