Abstract: The invention is directed to a precoat or body feed composition comprising a microbiological interception enhanced filter aid. Preferably, the microbiological interception enhanced filter aid comprises fibrillated lyocell nanofibers having coated on at least a portion of a surface thereof, a microbiological interception enhancing agent. The microbiological interception enhanced agent comprises a cationic material in combination with a biologically active metal. At least about 4 log reduction in bacterial interception is achieved with the microbiological interception enhanced filter aid alone or in combination with a bulk, untreated filter aid. A precoat composition including the microbiological interception enhanced filter aid can be used for one-step cold sterilization of beverages.

Abstract: The invention is directed to a microbiological interception enhanced filter medium, preferably having an adsorbent prefilter located upstream from the filter medium. Preferably, the prefilter is adapted to remove natural organic matter in an influent prior to the influent contacting the microbiological interception enhanced filter medium, thereby preventing loss of charge on the filter medium. The microbiological interception enhanced filter medium is most preferably comprised of fibrillated cellulose fibers, in particular, lyocell fibers. At least a portion of the surface of the at least some of the fibers have formed thereon a microbiological interception enhancing agent comprising a cationic metal complex. A filter medium of the present invention provides greater than about 4 log viral interception, and greater than about 6 log bacterial interception.

Abstract: There is provided composite media and a method of producing them. The composite media contain a coalesced composite mixture of particles of an active ingredient, binder particles, and stabilizing particles. The stabilizing particles fuse the composite structure to both front and back substrates while the binder particles fuse the particles of active ingredient to each other and to one of the front and back substrates.

Abstract: The present invention is directed to a microporous filter medium treated with a microbiological interception enhancing agent comprising a cationic chemical having a medium to high charge density and a molecular weight greater than about 5000 Daltons, adsorbed on at least a portion of the microporous structure, and a biologically active metal in direct proximity to the cationic chemical and also on at least a portion of the microporous structure, wherein the flow of fluid through the filter medium decreases in response to an amount of polyanionic acids present in an influent. Robust microbiological interception is still maintained due to the extended empty bed contact time as a result of the diminished flow rate.

Abstract: An apparatus and method useful for brewing a beverage. A brewing liquid, generally water, and in some cases brewing ingredients, are placed in a container having a bottom with openings that, due to surface tension of the liquid, do not allow the liquid to pass through the openings until the liquid approaches or reaches its boiling point. The liquid is heated to approach its boiling point by placing the apparatus in a microwave oven or by the use of an electrical resistance heater associated with the container. The brewed beverage is captured in a second, temporary container from which it may be consumed or served.

Abstract: The invention is directed to a microbiological interception enhanced filter medium comprising a microporous structure having a mean flow path of less than about 2 microns and made of an array of active particles. At least a portion of the surface of microporous structure has formed thereon a microbiological interception enhancing agent comprising a cationic material in combination with a biologically active metal. A microbiological interception enhanced filter medium of the present invention provides greater than about 4 log viral interception, and greater than about 6 log bacterial interception.

Abstract: An absorbent article containing a composite mixture of absorbent macroporous particles and binder particles. Preferably, the absorbent macroporous particles are those having a macroporous structure which allow for the rapid flow of liquid therein, e.g., aerogels, xerogels, cryogels, or mixtures thereof. The absorbent articles produced thereby are preferably thin and lightweight, but maintain an ample rate of absorption allowing for a more rapid uptake of higher volumes of liquids.

Abstract: A desiccant system and a method for producing the same wherein a container is provided with a desiccant sheet that is trapped within the container and a water vapor impermeable cover for the container making a water impermeable seal thereto. The sheet may have a first substrate, and optionally, a second substrate, and desiccant particles adhered to the first substrate or trapped between the first substrate and the second substrate. A binder material may fuse the desiccant particles to one another and to the substrates. The sheet may be trapped within the bottle due to its tendency to unfurl to a flat condition, or it may be adhered to an inner surface of the bottle.

Abstract: A method and apparatus for treating an oxygen containing gas (generally air) and/or water in an appliance such as a refrigerator washing machine, dryer or dishwasher with ozone so as to disinfect the water used within the appliance and use the ozone in the air to disinfect the interior space and the contents of the appliance. Arrangements may be made to provide disinfected water on demand. The ozone containing gas is provided when needed, or in the case of a refrigerator, at a time of the day when the refrigerator is not generally in use. The generator may include a source of ultraviolet radiation, a plenum for the air and a plenum for the water. The plenum for the water may be in the form of a tube which is transparent to ultraviolet. The diameter of the tube is preferably selected so that plug flow of water through the tube occurs. The ozone containing air and the disinfected water may be provided to a location remote from the appliance.
