Abstract: The present disclosure provides a filter cartridge, a filtration system and a process for filtering and disinfecting water for medical and/or dental purposes. Filter cartridge (10) comprises: (a) a vessel (16) comprising a first cavity; (b) a filter media (18) having a second cavity, wherein said filter media is disposed in said vessel thereby forming a first compartment therebetween an outer surface of said filter media (18) and an inner surface of said vessel (16); (c) a first end cap (14) attached to a first end of said vessel (16), wherein said first end cap (14) is configured to form a first outlet (12); wherein said filter cartridge is in the range of at least greater than 3 inches to 5 inches.

Abstract: Described is a combination method, including a device and system for disinfecting and decontaminating water lines, for example, dental water lines, in the absence of a primary chemical component.

Abstract: Contaminated drinking water and other liquids are decontaminated by contact with sorbents to remove toxic contaminants such as arsenic, as well as non-toxic contaminants. In regenerating the spent sorbents, the waste stream contains both toxic and non-toxic contaminants but only toxic components must be treated as hazardous waste and subjected to strict regulations for disposal. The inventive method regenerates spent sorbents in a process that minimizes the amount of hazardous waste for disposal. The bulk of contaminants are non-toxic and are first selectively removed from the spent sorbent, generating a non-hazardous waste stream. Toxic contaminants are then removed from the sorbent, generating a hazardous waste stream. Because the bulk of contaminants was removed in the first waste stream, the lower concentration of toxic contaminants in the second waste stream requires less material (e.g., ion exchange resin) for hazardous waste decontamination and disposition.

Abstract: Metal oxide modified or impregnated fibers as a sorbent to reduce contaminants such as arsenic from a fluid stream. The kinetics of the sorbent enable it for point of use or point of entry applications, including but not limited to household treatment of drinking water.
