Abstract
Embodiments of the present invention relate generally to systems and methods for preventing mineral scale deposits in an aircraft water system, and more specifically, within devices and water transport systems, such as coffeemakers and other galley equipment, as well as the water lines themselves.
Claims11
A scale prevention device configured for use on board a passenger transport vehicle, the scale prevention device comprising:
- (a) a cartridge comprising:
- an inlet configured to cooperate in-line with a water system,
- an outlet,
- internal inwardly angled side walls that extend along a length of the cartridge and that are separate from external cartridge walls, the internal inwardly angled side walls creating a funnel shape from a wide portion to a narrow portion, and
- a media cavity for liquid treatment, the media cavity having a scale prevention treatment media, and
- (b) a system to provide uniform fluidization of the scale prevention treatment media by fluid passing through the cartridge such that liquid entering through the inlet contacts the system to provide uniform fluidization and expands the scale prevention treatment media into the media cavity, the inlet directly connected to a domed umbrella feature comprising a dome and edges, wherein a concave face of the dome receives and redirects an incoming fluid flow path traveling in a first direction from the inlet by turning the incoming fluid flow in an opposite direction and forcing the fluid to flow out from under the edges of the domed umbrella feature, which diverts the incoming fluid flow path across substantially all of the scale prevention treatment media.

- an outlet,
- internal inwardly angled side walls that extend along a length of the cartridge and that are separate from external cartridge walls, the internal inwardly angled side walls creating a funnel shape from a wide portion to a narrow portion, and
- a media cavity for liquid treatment, the media cavity having a scale prevention treatment media, and
- (b) a system directly connected to the inlet that changes direction of an incoming fluid flow after delivery through the inlet such that the incoming fluid flow is forced in a reversed direction and then outward and distributed more widely across the fluid treatment media bed and expands the media bed into the media cavity.
