Abstract: A lightweight, portable, on-contact and on-demand, straw-style, high flow rate water purifying apparatus, tested and proven by an accredited and certified laboratory to meet or exceed Environmental Protection Agency (EPA) and NSF/ANSI P231 and 53 standards for a microbiological water purifier. The apparatus includes a shell and a hollow, elongated chamber that accommodates cleanable and replaceable water filtration and water purification media cartridges.

Abstract: A portable water purifying apparatus, including a shell and a hollow, elongated chamber. The apparatus includes a first opening that feeds into this chamber, through which the user draws contaminated water into the chamber, and a second opening for removing purified water from the chamber. Purification of the contaminated water drawn into the apparatus is effected by water purification media, which may include an ultrafiltration membrane; a halogenated resin; and granulated, activated carbon. The apparatus may also include one or more cleanable, removable, replaceable cartridges for containing the water purification media.

Abstract: A fortified liquid composition, comprising purified water, molecular oxygen at a level between 30 and 60 mg/l, and a combination of minerals in that purified water. The minerals include at least 0.002 mg/l boron, at least 0.0001 mg/I chromium, at least 0.045 mg/l cobalt, at least 0.019 mg/I copper, at least 0.086 mg/l iodine, at least 0.053 mg/l manganese, at least 0.36 mg/l potassium, at least 0.0003 mg/I selenium, at least 0.029 mg/l silica, at least 2.61 mg/l sodium, and at least 0.015 mg/l zinc.

Abstract: A device for the deionization of incoming water is disclosed. The device includes a tank and a generally hollow distributor tube in the tank for ingress into and downward movement of unpurified water through the tank. An opening adjacent the bottom of the generally hollow distributor tube and near the bottom of the tank distributes the unpurified water out of the generally hollow distributor tube. A mixed bed of purifying resin is within the tank, and surrounds the generally hollow distributor tube. The unpurified water travels upwardly through the tank where it is deionized to a high purity water by the mixed bed of purifying resin, after egress from the opening. The deionized water passes through a distributor and a filter before leaving the tank through an outlet.

Abstract: A device for the deionization of incoming water. The device includes a tank and a generally hollow distributor tube in that tank for ingress into and downward movement of the incoming water through that tank. Slots adjacent the bottom of the generally hollow tube and near the bottom of the tank are provided for distributing the incoming water out of the hollow tube. There is a bed of mixed bed ion exchange resin within the tank. This bed of resin surrounds the generally hollow tube, through which the incoming water travels upwardly. The water is deionized by the ion exchange resin, as it moves upwardly through the resin, after egress from the slots.

Abstract: A portable water purifying unit for treating microbiologically contaminated water. The water purifying unit includes a main body portion that is a generally hollow, preferably cylindrical container. A water purifying medium, preferably a halogenated resin, is contained within the generally hollow container. A giardia filter is placed downstream from the water purifying medium, and the giardia filter may be incorporated into a filter medium. The intake end of the invention may comprise either a fine mesh screen placed at the bottom of the generally hollow container, or a plurality of holes placed into the bottom of the otherwise sealed end of that container. The mouthpiece of the water purifying unit may comprise a pull-push type closure. When the closure is pulled, the closure is in an opened position, and water may be drawn through the water purifying unit. In contrast, when pushed, the closure is in the closed position, sealing the top of the unit.
