Pressure Filter - an overview ScienceDirect Topics

The advantage of pressure filters is that excess raw water pressure is not lost when the filtration process takes place, as is the case with an open rapid gravity filter system. About 3 m head may be lost in friction through the sand bed and the inlet and outlet fittings.

Pressure Filters - Solid Liquid Separation

Pressure Filters. Pressure Filters, with the exception of the Rotary Drum Pressure Filter, are semi-continuous type machines that enter a wash and cake discharge mode at the end of the filtration cycle. The filtration cycle may extend from 5-10 minutes on cake filtration applications and up to 8 or even more hours for the polishing of liquids.

The pressure-line filter should have an absolute rating, or have a Beta Ratio of 50 or higher. A pressure-line filter should not have a bypass. If the filter element clogs, it is better to stop flow to a servovalve than to contaminate it. Visual and electrical clogging indicators are available for most pressure-line filters.
