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 fromОнлайн-запрос

Sand Filtration by means of a sandfilter. Depending on the type of water, suspended solids concentration, oil and grease, COD/ BOD, iron contents, sand filters are sized differently, but the basic design data to clarify natural waters are the following:

A 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.
