Multimedia (sand) Filtration Calculation - Lenntech

For industrial water filtration purposes vertical filter bed speeds (ideal service flows) varying between 10 m/h and 25 m/h are used depending on the quality of the to be treated water. The higher the total suspended solids (TSS indicated in mg/l) content or the more turbid the water, the slower the vertical filter bed speed. Suspended solids consist of small particles such as silt, clay, grit, organic

Pressure Sand Filter Calculator WE - Water Engineer

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.

Vertical pressure filter - FV2B Filter - Degremont®

The FV2B vertical filter is fed with water, without turbulence, by the trough located above the filter media. Thus, the design is a downflow filtration. It supplies desalination plants under 10,000 m 3 /d. The water percolates through the filtering material that can be sand, sand + anthracite or Granular Activated Carbon (GAC). The water pressure is identical at all points on the filtering surface. At the same time,

Water Handbook - Filtration SUEZ

Pressure filters, designed vertically or horizon-tally, have cylindrical steel shells and dished heads. Vertical pressure filters (see Figure 6-2) range in diameter from 1 to 10 ft with capacities as great as 300 gpm at filtration rates of 3 gpm/ft². Horizontal pressure filters, usually 8 ft in diameter, are 10-25 ft long with capacities from 200 to 600 gpm. These filters are separated into compartments to allow

vertical pressure sand filter. Working Principle In pressure sand filter raw water flows down wards through the filter bed and as the suspended matter- which has usually been treated by addition of a coagulant like alum- is retained on the sand surface ands between the sand grains immediately below the surface. There is steady rise in the loss of head as the filtration process continues and the flow reduces once the pressure drop across the filter
