A filtration system interconnection structure includes a filter manifold and a filter cartridge in magnetic communication produced by two complementary correlated magnets capable of generating a magnetic force when in close proximity to one another. The filter magnet polarity transitions are aligned with the manifold magnet polarity transitions such that a repulsion force is generated between the magnets when the filter cartridge is inserted within the manifold sump. The magnetic repulsion force may be used to move a blocking mechanism or actuate a latch structure in the manifold to secure the filter cartridge within the manifold sump upon insertion, or to provide non-contacting actuation of a downstream valve so as to permit or prevent the flow of fluid. Utilizing correlated magnetism in a filter interconnect further provides enhanced authentication and/or anti-counterfeiting means to ensure that only authorized or OEM filter cartridges can be installed.

Disclosed is a filter element butt joint mechanism, including: a fixed base with a mounting cavity; a butt joint base arranged in the mounting cavity and close to an inner end of the fixed base; a filter element including a housing, a head of the housing being inserted into the mounting cavity from an outer end, an insertion pipe being formed at the head of the housing; a limit sliding-clamping mechanism; and a screw transmission mechanism, wherein a groove is formed in the head of the housing, and an insertion pipe is formed in the groove; a boss matched with the groove is formed on the butt joint base, and a plug-hole matching the insertion pipe is formed on the boss.

An interconnection scheme between a filter cartridge and its corresponding manifold whereby a magnetic shear force is introduced to remove a blocking mechanism that would otherwise prohibit attachment. The magnetic shear force may also be employed to activate or deactivate a switch or valve, or engage or disengage an engagement mechanism relative to other components upon interconnection. The magnetic shear force is generated by complementary correlated magnet structures moved into close proximity to one another. The interconnection scheme may be a linear or rotational attachment of the filter cartridge with respect to the manifold. A valve assembly utilizing magnetic shear force may be employed to activate a bypass action between a manifold ingress port and egress port, thereby allowing water to flow when a filter cartridge is removed from the manifold and directing water to the filter cartridge when the valve assembly is activated.

An above grate based inlet filter system for erosion and sediment control comprises a natural fiber filter mat configured to extend beyond the perimeter of the grate and a securing mechanism, such as magnets, configured to securing the filter mat around the perimeter of the grate. The system may include a filter berm secured in vicinity to the mat, and a rectangular array of magnets coupling the filter mat to the grate. The natural fiber filter mat may effectively be a coir fiber filter mat extending beyond the perimeter of the grate, wherein the coir fiber filter mat is formed of vertically aligned coir fibers. The optional filter berm may be effectively formed as triangular in cross section and formed of 100% reticulated polyether foam and formed to be at least 3 in height.

A recycling bin and a cleaning device. The recycling bucket includes: an upper cover; a filtering part, which is detachably connected to the upper cover and which is provided with a plurality of filtering holes, a filtering space being formed between the filtering part and the upper cover; a sewage channel, which passes through the filtering part, and which includes a channel outlet that is located in the filtering space, the channel outlet being located above the filtering part.

In at least one illustrative embodiment, an electromagnetic filter may include a pipe and a magnetic field generator such as an array of permanent magnets. The magnetic field generator generates a magnetic field through a filter section of the pipe. Multiple filter elements are positioned within the filter section of the pipe. The filter elements include a magnetic material and a biorecognition element to bind with a microorganism. The biorecognition element may be a bacteriophage that is genetically engineered to bind with the microorganism. The magnetic field forces the filter elements to positions within the filter section of the pipe. A fluid media may be flowed from an inlet of the pipe to an outlet of the pipe, through the filter section. The fluid media may be a liquid food such as fruit juice. Other embodiments are described and claimed.

A gravity-fed filtration system and method of initiating flow from a filter cartridge to a holding reservoir for a gravity-fed filtration system. The method comprises providing a filter cartridge having a filter magnet, a holding reservoir for filtered fluid, and a first reservoir having a recess receiving cavity in a bottom surface thereof for receiving ingress fluid. Upon inserting the filter cartridge into the recess receiving cavity and moving the filter magnet to be in in magnetic communication with the carrier magnet, a magnetic force moves the carrier magnet from a first position which blocks fluid flow, to said second position which allows fluid flow to the holding reservoir.

A filtration system and method of using the same. The method comprises the steps of guiding, by alignment rail and mating boss, a filter cartridge into a manifold housing; aligning a filter magnet with a corresponding manifold magnet; rotating, by attractive magnetic forces, the manifold magnet upon rotation of the filter cartridge into an installed position; and actuating, by attractive magnetic forces, a manifold valve.

An in-line or in situ filter is disclosed for filtering fluid flowing through a hydraulic system, and particularly an automotive hydraulic system. The filter has a magnetic base with a central opening at its outlet end and a seat with a central opening at its inlet. The base and the seat are joined by a cylindrical filter element made of a magnetically susceptible mesh screen material. A spring within the filter element biases a ball against the central opening of the seat normally sealing off the opening and forcing fluid to flow through the filter element to be filtered before exiting through the central opening of the base. If the mesh screen becomes clogged, backpressure forces the ball away from the seat against the bias of the spring to allow fluid to bypass the filter element and flow directly through the filter. In the process, ferrous debris entrained within the fluid flow continues to be captured by attraction to the magnetic base and the magnetized filter element.
