The present invention relates to a water filter comprising: a water filter cartridge including a water filter cartridge body, a water filter cartridge outlet cap having a water filter cartridge outlet, and a water filter cartridge sealing cap. The water filter cartridge body in a hollow cylinder form with a central hollow space, one end of the water filter cartridge body is coupled with the water filter cartridge outlet cap so that communicating with the water filter cartridge outlet, and the another end of the water filter cartridge body is coupled with the water filter cartridge sealing cap. The water filter cartridge outlet in a hollow cylinder form protruding from one surface of the water filter cartridge outlet cap. The filter container for containing the water filter cartridge therein, wherein the filter container including a filter container body, a filter container cap, a filter container inlet, and a filter container outlet, wherein the filter container inlet and the filter container outlet arranged at a filter container body bottom. The filter container body having a filter container outlet cylinder hole provided at the filter container body bottom for receiving the water filter cartridge outlet, so that when water flows into the filter container through the filter container inlet will surround the water filter cartridge and flows through the water filter cartridge body into the central hollow space of the water filter cartridge body, and flows to the filter container outlet through the water filter cartridge outlet. The filter container body having ribs provided at an inner surface of the filter container body bottom to reinforce for the filter container body bottom and providing gaps placed between the inner surface of the filter container body bottom and the outer surface of the water filter cartridge outlet cap, so that replacements or miscellaneous uses of the water filter cartridges become impossible.

A method for manufacturing a filter medium includes providing a computer-readable three-dimensional model of the filter medium including a plurality of segments, each segment of the three-dimensional model being configured to be converted into a plurality of slices that each define a cross-sectional layer of the filter medium, each segment including an undulating layer extending along a predetermined direction that is different than the predetermined direction of the undulating layer of the other segment; and successively forming each layer of the filter medium by additive manufacturing.

A filter cartridge has media construction, a housing, and a first end construction. The first end constructions includes an outer radial wall with circumferentially spaced connecting sections; each connecting section having a plurality of helical profiles extending at a helix angle. The filter cartridge is removably attached to a filter head, which has mating connecting segments. A bowl cartridge assembly is also provided including connecting sections with a plurality of helical profiles.

A filter for filtering particulates from a fluid stream includes a filter element, a first end cap, a second end cap, and a wrap. The end caps are respectively secured to the ends of the filter element to form a fluid tight seal therebetween. At least one of the end caps defines an opening therethrough in fluid communication with the interior passage of the filter element. The wrap is in the form of a strip secured to at least the filter element. The wrap comprises a conductive layer comprising an electrically-conductive material. The wrap is wrapped around the filter element such that at least forty percent of the outer surface area is covered by the conductive layer.

A multi-functional water filtration apparatus includes an outer housing defining a receptacle for receiving a filter assembly and having an inlet port at a first end for intake of unfiltered water and being open at a second end. The filter assembly includes an endcap closing the second end of the outer housing and a filter element enclosed within the outer housing. The endcap has an outlet port for dispensing filtered water. The outer housing has a flow passageway extending between the inlet port and the outlet port. The filter element is disposed in the flow passageway and has an upstream side in fluid communication with the inlet port and a downstream side in fluid communication with the outlet port. In certain aspects, the filtration apparatus provides multiple attachment options. In further aspects, a method of filtering water is provided.

A swimming pool filter element capable of automatically dosing. The swimming pool filter element includes a folding filter element and a doser filter element. The folding filter element includes a filter membrane and end covers, the end covers each having an upper end cover and a lower end cover. A wrench cover is arranged at the upper end of the upper end cover. The doser filter element includes a doser end cover, a doser lining and a doser shell. The doser filter element is added into the folding filter element, so that a water flow needing to be filtered firstly passes through the filter membrane of the folding filter element, solid large-particle impurities are filtered out, then the water flow enters the doser filter element and makes contact with sterilization tablets placed in the doser filter element, the tablets are dissolved, and finally water with dissolved tablets is discharged into a swimming pool.

A filter device provides for designs that permit variable levels of solid particle and water molecule removal. The filter device retains the particles and the water molecules in the filter medium when removed, thus avoiding the re-entry of the particles and water molecules when the power system has cooled down as is now likely in conventional filters currently in use. Further, the filter device traps the water molecules already present in the fluid being filtered (i.e., “native water”), as well as any moisture resulting from condensation that may be introduced into the lubrication system whenever it is opened.

An apparatus for storing organic materials includes: a body having an opening for receiving the organic materials to be stored; an outlet formed in the body through which the organic materials are unloaded from the body; and a cooling fluid circuit for circulating cooling fluid through the organic material collected by the hopper.

The present invention relates to filters used to remove debris from water being sucked into a piping system. It has particular application use in nuclear power plants, which, after a loss of coolant accident, must pump cooling water back into the reactor core from a collection sump. This water may contain various types of debris that must be removed before the water is sent back into the reactor cooling system. There are restrictions on the allowable pressure drop across the strainer and the space available for installing this equipment. The finned strainer of the present invention addresses these issues while maximizing the quantity of debris filtered from the water.
