A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.

A pool strainer basket insert system and method are contemplated in which a high porosity, coarse fibrous mass is inserted in a pool skimmer basket. Via optimization of the material properties of the fibrous mass and configuration such that approximately 50% of the fibrous mass is located above the waterline and 50% below the water line the problems of the prior art may be solved via the retaining properties of the fibrous mass, enabling insects and small organic matter to be retained and preventing their migration back to the main body of the pool.

A fluid filter, filtering medium composition, and associated process for removing compounds containing sulfur or other undesirable contaminants from fluids along with unpleasant tastes and odors.

An embodiment of this disclosure provides a liquid treatment device, provided at a carbon block used for post-treating a liquid treated by the carbon block. The liquid treatment device includes: a housing; a cover; a sealing portion; a lower treatment unit; and an upper treatment unit. The liquid treatment device and the carbon block may be detachably mounted mutually, thereby enabling the liquid treatment device to be replaced independent of the carbon block. Furthermore, the liquid treatment device includes an upper treatment unit and a lower treatment unit, and a liquid inlet is provided in the housing of the liquid treatment device, thereby making distribution of the liquid flow in the carbon block more uniform.

A filtration device comprising a media basket, a baseplate, and a canister. The media basket is affixed to the baseplate. The canister has a cavity therein and is detachably coupled with the baseplate to enclose the media basket. The media basket contains a porous filtration material that efficiently removes contaminants from liquid. The device is configured to establish a first siphon to convey liquid from outside the device into the canister cavity through a canister pipe when a liquid level outside the filtration device is higher than the top of the weir in the canister pipe and configured to establish a second siphon to convey liquid from canister cavity through the top of a center riser pipe and out an outlet pipe when the first siphon has been established and the liquid level outside the filtration device is higher than the top of the center riser pipe.
