Abstract: It is an object of the present invention to provide a filter having excellent filtration rate and excellent permeability and a method for producing the same. To achieve the above object, the present invention provides a filter comprising a porous metal support having the first pore size; and a metal coating layer formed on the support and having the second pore size smaller than the first pore size, wherein the coating layer has a three-dimensional pore structure by bonding flake-shaped metal powders. The present invention also provides a method for producing the filter. According to the present invention, as the flake-shaped second powders form a coating layer, the porosity increases and the permeability increases, and as the flow channel becomes more complicated, the filtration rate also increases.

Abstract: The description relates to methods and apparatus that enable the efficient introduction of gases like air, oxygen and ozone into aqueous liquids. Gases are introduced into liquids for making that gas chemically or biologically available at a minimum energy expenditure. Impinging jets of liquid are directed into a pressurized saturation vessel having a gas-filled headspace and a saturation zone below the surface of the liquid at a velocity sufficient to create a turbulent impact and plunge zone. The resulting turbulence and mixing of gas and liquid in that zone under pressure, causes the gas to be driven into the liquid in the vessel and breaks up the gas and the liquid into a churning flow and creates a large number of bubbles. The resulting gas-enriched liquid is discharged from the vessel at an outlet to ensure a minimum of bubbles in the gas-enriched liquid.

Abstract: A filter for in-line or inlet applications. The filter may include a spindle for supporting a filter element. In some embodiments, the spindle may be fixedly attached to a filter cap or filter body.

In addition, or alternatively, a filter consistent with the present disclosure may be provided with a splash cap that allows use of the filter as a protected inlet for fluid flow. When used as an inlet filter, fluid may enter the filter through the splash cap and exit the filter through hose or tube coupled to the filter body. Both uses allow for serviceability.

Abstract: Air purifier systems for enclosed environments and processes for purifying air within the enclosed environments generally include four stages of filtration. The four stages of filtration include exposing the air to a carbon pre-filter followed by exposing the air to a particulate filter. The air is then fed through a photocatalytic filter and subsequently discharged back into the environment. The systems and processes deodorize, remove particulate matter and destroy airborne pathogens within the enclosed environment.

Abstract: An atmospheric water generation system comprises water vapor consolidation systems configured to increase the relative humidity of a controlled air stream prior to condensing water from the controlled air stream. The water vapor consolidation system comprises a fluid-desiccant flow system configured to decrease the temperature of the desiccant to encourage water vapor to be absorbed by the desiccant from an atmospheric air flow. The desiccant flow is then heated to encourage water vapor evaporation from the desiccant flow into a controlled air stream that circulates within the system. The humidity of the controlled air stream is thereby increased above the relative humidity of the atmospheric air to facilitate condensation of the water vapor into usable liquid water.

Abstract: A carbonation system for a beverage appliance or machine that can include a liquid chamber and a carbonation chamber separated from the liquid chamber by a wall of the carbonation chamber is disclosed herein. In some implementations, the liquid chamber is defined by a liquid tank (e.g., a water tank), and the carbonation chamber is defined by a carbonation tank. The carbonation system can move liquid (e.g., water) from the liquid chamber to the carbonation chamber and introduce carbonating gas (e.g., carbon dioxide) into the carbonation chamber to create a carbonated liquid (e.g., a carbon dioxide water dissolution, such as carbonated water, sparkling water, or seltzer).
