摘要： A method and apparatus for filtering a fluid flowing from a fluid supply duct in a first direction through a filtering medium in which separate solid particles or concentrate are released from the filtering medium by a back-flush. The method and apparatus has a moving means, such as a diaphragm, which receives the pressure of the fluid at both the inlet and outlet of the filter. In response to a changing pressure, such as by opening of an outlet valve, the moving means operates, e.g., the diaphragm changes its position, and operates to send a supply of the fluid through the filter medium in a second direction which is opposite to the normal first direction of fluid flow.

摘要： A sealing member for a multi-well microfiltration plate (10) comprises a flexible sealing material (20), which in response to the application of differential pressure, will flex or collapse in the direction of filtration along the contour of each individual well (12). A process maintains a differential pressure substantially constant over a multi-well microfiltration plate (10) comprising placing said flexible sealing member (20) over the surface of the multi-well microfiltration plate (10) having individual wells (12), stretching the flexible sealing member (20) so as to seal the perimeter of each individual well (12), creating a differential pressure around said multi-well microfiltration plate (10) covered with said flexible sealing material (20) and filtering a material (22) from each occupied well (12) at a rate independent of the filtration rate of any other well (12) while maintaining a substantially constant differential pressure around the multi-well microfiltration plate (10) until filtration in the last well (12) containing material (22) is complete.

摘要： A strainer device for filtering water to an emergency cooling system in a nuclear power plant containment area having a lower part which forms a pool in which the strainer device is mounted. The device includes a strainer housing (1) with separate strainer walls between which a flexible shield unit (6) operates. The unit is arranged to be kept in a first position when water is drawn through one of the strainer walls, in which position it interrupts the connection between the other strainer wall and a suction conduit (4). By inherent flexibility, the shield unit is automatically switched over to a second position which opens the connection between the second strainer wall and the suction conduit, as soon as the first strainer wall is clogged by impurities to such an extent that a low pressure arises in the space between the first strainer wall and the shield means unit, which low pressure brings about the switching-over by its suction effect.

摘要： A filter backflushing system including an accumulator containing a pressurized bladder which propels a supply of backwash fluid contained within the accumulator in a reverse direction through a filter element. While the backwash fluid is pumped within the accumulator, an inert gas inside the bladder is compressed against the inside walls of the accumulator. Upon reaching a pressure of approximately 300-600 psi, the filtered fluid is released from the accumulator and the full energy of the compressed gas is released as well. This release produces a high pressure rapid burst of backwash fluid which effectively removes clogging contaminants from a filter element.

摘要： A self-cleaning pre-filter system (10) generally comprises a system inlet (11); a sediment filter (13) having a filter inlet (15) in selective fluid communication with the system inlet, a selectively openable drain port (18) and a filter outlet (16), separated from the filter inlet and the drain port by a filter screen (20); a pressure accumulator (28) having a first chamber (31) in open fluid communication with the filter outlet and having a sealed second chamber (32) containing a compressible medium, the first chamber and the second chamber being separated one from the other by a flexible diaphragm (30); and a system outlet (12) in selective fluid communication with the filter outlet and the first chamber. A controller (32) operates valves to periodically back flush the sediment filter utilizing energy stored in the pressure accumulator. Any detritus removed from the filter screen during the back flush process is immediately discharged from the system through the drain port (18).

摘要： A system which separates and filters fine, particulate, suspended solids from liquid. The system consists of a vessel (1) of appropriate design for solids/liquid mixture processing, with an inlet (2a) for mixture feed and outlets (3, 4) for processed/filtered liquid and solids concentrate; a means of inducing positive head pressure (10, 11) on the mixture feed; an acoustic energy source (8a) operating in an infrasonic or low frequency sonic range, and a fine mesh screen (7a) mounted so as to be hydraulically coupled with the acoustic energy. Acoustic energy transmitted via pressure wave promotes separation of the solids/liquid mixture fractions and induces an oscillatory field of flux acting on and through the screen (7a), the resultant effect of which serves to promote continuous separation, liquid filtration and self-cleaning of the screen. A beneficial side effect of the low frequency acoustic energy is the stressing and killing of bacteria contained in the liquid being processed.
