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 composite filtration material is provided as well as a method for preparing the same. A filter is also provided that is fabricated with the presently disclosed composite filtration material. In various aspects, the provided composite filtration material may include activated carbon doped with silver and/or iron oxide. A one-step thermal decomposition process is provided that may be employed to prepare the provided composite filtration materials. The one-step thermal decomposition process may include dissolving one or more precursors in water, spraying the dissolved one or more precursors onto activated carbon, and heating the activated carbon saturated with the one or more precursors for a predetermined amount of time. The inventors have found that the provided composite filtration materials are more effective (e.g., higher removal of pollutants) and have a longer service life as compared to typical activated carbon filtration materials.

A filter for a liquid purifier, comprising: a filter housing having an inlet to receive water and an outlet to discharge the water; and a filter module provided in the filter housing, and configured to purify water introduced through the inlet, and to provide the purified water to the outlet, wherein the filter module includes a carbon block having a hollow tube shape by mixing activated carbon, a binder, ferric hydroxide, and titanium oxide, and the binder is mixed at a ratio of 13% to 23% by weight.

A device and a method for removing fats, oils and/or grease (“FOGs”) from water comprise a separator, wherein the separator removes the FOGs that separate from the water under gravity, and a filter wherein the filter removes the FOGs remaining in the water after the water has passed through the separator. The filter comprises several layers having different compositions suitable for removing FOGs from water, including a layer comprising granular activated carbon bonded together and wrapped in polyester.

A method of removing carbon dioxide from a gas can include providing a gaseous feed stream including a carbon dioxide gas and adsorbing the carbon dioxide gas with a porous carbon sorbent. The method can further include de-adsorbing the carbon dioxide and combining the carbon dioxide with a substantially pure hydrogen gas to produce at least one of methane and methanol. The adsorbing and de-adsorbing of the carbon dioxide gas can be conducted by an electric swing adsorption.

A hybrid graphene material and a filter capable of retaining, in whole or in part, polyaromatic hydrocarbons, carbonyl and other smoke compounds from tobacco products or industrial processes, having as adsorbent substances activated carbon and graphene materials, both supported by the same matrix and in the same filter compartment, which may or may not be attached to another conventional filter compartment of cellulose acetate fibers or similar polymer, and a method for manufacturing such material.

Described are multi-layer filters of a type commonly known as “depth filters” and related devices and methods, with the filters containing a layer that includes polyaramid fiber, synthetic filter aid, and polymeric binder.
