Abstract: A filter element assembly used to filter liquid-state process stream. The assembly includes first and second tubes. A ring is seated in one of the tubes. One or more filter elements extend from the ring into one of the tubes. The ring has a lip that extends beyond the outside of the tubes. Opposed open ends of the tube abut opposed surfaces of the ring lip. A seal surrounds the open ends of the tube and the ring lip. A clamp surrounds the seal. Liquid that flows between the ends of the tubes and the ring lip forces the seal against the clamp and the outer tubes to prevent the liquid from flowing beyond the seal.

Abstract: The present invention is directed to a filter module that may incorporate sensors to measure various characteristics of fluid flow and filtration. The sensors may be MEMS and may measure the temperature, flow rate, pressure, etc. of the fluid. One or more MEMS sensors may be included in a sensor package which, in turn, may be included in a sensor component. The latter, which may also include a processor, conductor pins, etc. for data communication, may be coupled to a sensor port in such a way as to allow contact between the sensor(s) and the fluid. Sensor measurements may be used to determine the occurrence of harmful events, such as cavitation or particle breakthrough, or to predict the remaining service life of a filter element.

Abstract: A method of filtering a bath (1,31) having a liquid containing particles of varying sizes therein and the recirculation and filtering system. The method and system require providing a recirculation route from the bath outflow and returning to the bath inflow. The route includes a first path communicating with the bath outflow and having serially a first controllable valve (5,9) and a filter having a relatively large pore size. The route also includes a second path communicating with the bath outflow and having serially a second controllable valve (11,15) and a filter having a relatively small pore size. There is a return path from each filter to the bath inflow. The return path from each filter can be a separate path or the paths can be connected at the output end before returning to the bath. The particle count in the recirculation route can be monitored either between the bath outflow and the first and second valves (3), between the bath inflow and each of the filters having large and small pore size (23), or both for controlling operation of the first and second valves. The controllable valves can also be controlled by a time program, bath operation program or the like.

Abstract: A cartridge filter element of known degree of filtration is the central part of the meter for monitoring water quality with respect to suspended particles. Typically the holder of the filter element is located in a sampling line which is at a point downstream of the commercial primary filter being monitored. Sensors of rate and differential pressure send signals to the microprocessor of the meter which measures the transmissibility of the monitor cartridge filter. Thus the microprocessor calculations determine the quality of the commercial primary filter effluent. Also microprocessor logic manipulates the steps of the meter and sends signals to display, controls and alarms depending on the water quality observed. A tangible additional benefit of this meter in comparison to an optical turbidity meter is the identification of the composition of the solids. The flushing step reveals the response of the monitor filter to solids removal by flushing agent or agents. This can help with full scale design of chemical treatment of injection wells which have been inadvertently damaged by solids.

Abstract: A shifter mechanism for a filter press, which shifter mechanism incorporates a vibrating mechanism for effecting bumping of individual filter plates during the separation thereof from the closed stack to assist in dislodgement of filter cake from the individual filter plates. The vibrating device can selectively vibrate or bump the individual filter plates responsive to the weight of the filter plate being bumped, whereby the vibrating device will be activated only upon sensing a filter plate having a weight greater than a predetermined value so as to be indicative of an undesired quantity of filter cake being adhered thereto.

Abstract: A method and apparatus for automatically propelling a charge of backwash fluid by a compressed gas such as steam to backwash a filter in a filter pair. The method and apparatus provides for backwashing a filter with at least three backwash phases, a first mainly comprising a charge of backwash fluid passing through the filter with significant speed, a second relating to use of flashing steam for secondary cleaning and scrubbing of the filter elements, and a third relating to use of low pressure steam for autoclaving and sterilizing the filter.

Abstract: A security system for a fluid filtration device and, more particularly, a security system that is adapted to pair a filter with a fluid filtration device, log an effectiveness of each individually serialized filter, prevent re-usage of a filter in more than one filtration device and prevent usage of a filter for greater than its preprogrammed lifespan.
