Pressure Filtration - Water Treatability Database | US EPAIncluded Processes: Bag Filtration and Cartridge Filtration. Pressure filters are in many respects similar to conventional rapid filters. The main differences are that the media is contained in a pressure vessel (such as a steel tank) and that they are operated under pressure provided by means of a pump or high-pressure water.pressure filter water treatment,Filtrationfilter. These filters are still in use in some small plants, especially in the western United States as well as in many developing countries. They may also be used as a final step in wastewater treatment. Modern filters are classified as: Gravity Filters (Rapid Sand or High Rate-Dual media-Multi- media) or Pressure Filters (Sand.
