Pressure Filtration

A pressure filtration system is similar to a gravity pressure system except that it is completely enclosed in a pressure vessel and is operated under pressure. This type of filtration system results in lower installation and operation costs in a small plant but is less reliable than a gravity filter. These reliability issues prohibit the use of pressure filters in many treatement systems. The filtration rate is 2 - 3 gpm/sq. ft.
