The present invention relates to a self-alarm multi-stage complex screen filter for micro-irrigation and the assembly method thereof. The filter comprises a housing, an alarm, a multi-stage screen filtering element, and a segmented brush. The housing comprises a left housing, a middle housing, and a right housing. The multi-stage screen filtering element comprises a plurality of screen filter cylinders. The segmented brush comprises a plurality of bristle frames, a plurality of connecting rods, a connector and a power device. The middle housing is provided with a water inlet. The left housing is provided with a discharge pipe. The installation, disassembly, repair, maintenance of the filter of the present invention can be done more conveniently.

The present disclosure is directed to at least one embodiment of a filter that is configured to remove contaminants utilizing a first conductive mesh (e.g., first electrode) and a second conductive mesh (e.g., second electrode) that extends around the first conductive mesh. For example, the first conductive mesh may receive a first electrical signal and the second conductive mesh may receive a second electrical signal such that the first and second conductive meshes are oppositely charged from each other (e.g., the first conductive mesh is positively charged and the second conductive mesh is negatively charged). Anions that are present within the fluid or generated by an electrical field between the first and second conductive meshes may interact with the contaminants such that the contaminants are attracted to at least one of the first and second conductive meshes, respectively.

A filter apparatus positionable outside a washing machine and connectable to a drain device of the washing machine, the filter apparatus including a filter case including a case inlet configured so that, with the filter apparatus connected to the drain device, water from the drain device is flowable through the case inlet into the filter case, and a case outlet configured so that, with the filter apparatus connected to the drain device, water in the filter case is flowable through the case outlet out of the filter case; a filter detachably mountable inside the filter case so that water flowing through the case inlet is flowable through a surface of the filter to filter foreign substances from the water, and then to the case outlet; a filter cleaning device configured to clean the surface of the filter; and a controller configured to control the filter cleaning device.

A washing machine comprising: a housing having a loading inlet that is open; a tub to be positioned inside the housing; a door to open and close the loading inlet; a detergent supply device provided in a first space formed between the housing and the upper part of a first side of the tub to supply detergent to the tub; a pump device provided to pump washing water inside the tub; and a filter provided to filter the washing water flowing in from the pump device.

Fluid filtration devices and methods of filtering fluids are described. The devices generally include a housing, a hollow filter assembly, a rotating cleaning assembly and a device to measure the accumulation of solids in the filter housing. In some embodiments the accumulation of solids is measured by measuring the torque required to rotate the cleaning assembly. Torque may be measured directly, such as with a torque sensor, or indirectly, such as by measuring the current used by an electric motor to drive rotation of the cleaning assembly. In some embodiments a purge valve is opened to remove accumulated solids from the housing when a certain level of solids accumulation is detected.

The system (10) comprises a casing (12) internally defining a cavity (14) and comprising, in turn, an inlet (16) configured to receive a fluid that contains microplastics and leading into the cavity (14), and an outlet (18) configured to deliver the fluid contained in the cavity (14), from which the microplastics have been substantially removed. A filtering assembly (100) contained in the cavity (14) is configured to be crossed by the fluid entering the casing (12) through the inlet (16) and exiting through the outlet (18), thus internally trapping the microplastics. A compacting assembly (200) is situated in the cavity (14) and configured for collecting and compacting the microplastics trapped by the filtering assembly (100). A driving assembly (300) is configured to drive the compacting assembly (200). A storing container (20) is housed in a storing chamber (14c) defined by the cavity (14) and facing towards the compacting assembly (200), and is configured to store the microplastics collected and compacted by the compacting assembly (200). A draining pump (400) is configured for taking in the liquid contained in the storing chamber (14c) and pushing the liquid out of the casing (12).
