Rapid sand filters are divided into two main types: (1) gravity filters and (2) pressure filters. The principles of the two types of filters are identical. 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.Filtration - MRWA,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.

Rapid Sand Filtration | SSWM - Find tools for

Rapid sand filtration is a purely physical drinking water purification method. Rapid sand filters (RSF) provide rapid and efficient removal of relatively large suspended particles. Two types of RSF are typically used: rapid gravity and rapid pressure sand filters. For the provision of safe drinking water, RSFs require adequate pre-treatment (usually coagulation-flocculation) and post-treatment,FILTRATION - Environmental Protection Agency,3.3 slow sand filter control 15 3.4 slow sand filter cleaning and resanding 15 3.4.1 worker safety and hygiene practice 15 3.4.2 recommended procedure for cleaning a slow sand filter 16 3.4.3 recommended procedure for resanding a slow sand filter 16 4 rapid gravity and pressure filtration 19 4.1 rapid gravity filtration 19 4.2 pressure,Sand filter - Wikipedia,The final key design point is to be sure that the fluid is properly distributed across the bed and that there are no preferred fluid paths where the sand may be washed away and the filter be compromised.
