Embodiments of the present disclosure include a screen basket apparatus includes a substantially vertical cylindrical frame and a synthetic screening surface secured to the frame. The synthetic screening surface may be configured to separate carbon or resin from a slurry of a carbon-in-leach, carbon-in-pulp, resin-in-leach, or resin-in-pulp material as fluid flows from outside to inside the screen basket apparatus such that carbon or resin is retained on an external surface of the synthetic screening surface. The cylindrical frame may be a grid frame and the synthetic screening surface may include a plurality of replaceable screen assemblies attached to the grid frame. The grid frame may include a plurality of openings and each of the plurality of openings is configured to receive a respective one of the plurality of replaceable screen assemblies. The synthetic screening surface may include injected molded thermoplastics, thermoset polyurethanes, and/or other polymeric materials.

An automatic flushing device for a screen filter of a biogas slurry drip irrigation system and a use thereof are provided. The automatic flushing device includes a feeding mechanism, a filter unit, a discharging mechanism and a control mechanism, where the filter unit is provided with a feeding end fixedly threaded to a discharging end of the feeding mechanism and a discharging end fixedly threaded to a feeding end of the discharging mechanism; and the control mechanism is clamped on a pipe of the feeding mechanism. The automatic flushing device enhances the cleaning strength and uniformity of ultrasonic waves to the filter screen. The ultrasonic vibration rod is nested inside the upper filter casing through the externally-threaded hollow cap and a threaded top portion of the upper filter casing, which greatly facilitates the cleaning, replacement and maintenance of the ultrasonic vibration rod.

The invention relates to a candle filter element for installation in a pressure vessel or for implementation in a tank or basin open to atmosphere. Main parts of the candle filter element are a fixing device for the connection to the housing, a coupling part to connect the support body with the fixing device, a support body for the filter material with integrated dip channel and a bottom part.

The invention relates to a candle filter device, primarily for filtration of solids from liquids, and containing one or more candle filter elements and the process of operating the same.

A filter pulsation dampening device has a replaceable filter element including a plurality of baffles disposed next to each other or a flexible valve that is disposed proximate a baffle.

A complete fuel tank maintenance and cleaning system. This apparatus and method are capable of effectively cleaning an underground or aboveground storage tank by implementing a multi-stage filtration and removal system, and effectively removing contaminants from tank surfaces by using the product or alternative as a streamed cleaning agent within the storage tank.

A method for filtering particulate down to 0.5 micron from cooking oil at a filtration temperature of up to 425° Fahrenheit is provided. The method includes providing a filter having a non-woven panel of randomly oriented fibers of polyphenylene sulfide (PPS) material and exposing the filter to the oil for a period of time while applying a pressure or vacuum to move the oil through the filter for filtering particulate from the cooking oil.

A filter cartridge for a whole house water filter includes a cylindrical, or tubular, filter media coupled to a mixer tank with improved high flow mixing features. The mixer tank includes a bowl in which a flow diverter, a flow guide with angled fins and a filter media are provided. The flow diverter has a concave portion, i.e., a mushroom-shaped portion, the interior of which is in fluid connection with a central passage through which filtered water flows. In operation, the filtered water flows through the central passage and is deflected by the concave interior of the flow diverter down through the angled fins of the flow guide. The filtered water then passes out through an outlet. The mixer tank stirs the filter media and water mix to increase the kinetics of the mixing process.

A filter device is provided with a filter element for filtering a fluid. The filter element has a filter medium body with an end plate arranged at an end face of the filter medium body in relation to a longitudinal axis of the filter medium body. A filter base housing receives the filter element. An assembly component for assembly and disassembly of the filter element in the filter base housing is connectable to the end plate and to the filter base housing by rotation about the longitudinal axis. The assembly component has interlocking elements. An interlocking counter element is arranged at the end plate. The interlocking elements can be brought into axial interlocking connection with the interlocking counter element, while enabling a free rotatability in rotational direction about the longitudinal axis. The interlocking counter element is a circumferential interlocking collar with insertion ramps for insertion of the interlocking elements.

A sub-component of a replaceable filter element that is interfacably sealing a standpipe includes an end cap, said second end cap defining a first central opening; a central tube extending from the first central opening of the second end cap, wherein the central tube defines an inner surface, an outer surface and a top surface, wherein the top surface defines a second central opening, wherein the central tube includes an actuator excluding keys, free ends, or projections; and a standpipe seal disposed proximate the top surface of the central tube, wherein the standpipe seal defines a third central opening.
