ABSTRACT:
An apparatus for hyperbaric filtration includes a sealable filtering vessel including an internal filtering cavity. A porous filtering plate is mounted in the vessel. The filtering plate divides the cavity into a first chamber wherein the filter cake is held by the filtering plate and a second chamber. A pressurized fluid source is connected by a delivery conduit to the filtering vessel so as to allow the delivery of pressurized fluid to the first chamber. An exhaust conduit is connected to the filtering vessel in communication with the second chamber. A rotary flow control valve in the exhaust conduit is connected to a drive motor so that fluid pressure may be released in a pulsating manner. This serves to vibrate the filter cake and filtering plate freeing moisture for removal with the passage of the pulsating pressurized fluid from the vessel. A circuit is also provided for supplying an electric current to the filter cake during filtering so as to further improve filtering efficiency. A method of hyperbaric filtration is also disclosed.
