A water purification system for purifying water flowing through a water flow path. The system includes a water purification device having an inlet and an outlet in the water flow path and at least one interior volume communicating with the inlet and outlet. A purification medium is disposed within the interior volume of the water purification device. A flow control system is provided controlling a volume of purified water dispensed from the outlet. The flow control system includes an input device configured to allow a user to input a desired volume of purified water to be dispensed from the outlet and a sensing device coupled with the electronic input device and operative to determine the volume of purified water being dispensed from the outlet. A flow regulation device is coupled with the flow control system and operative to stop the discharge of purified water at the outlet upon reaching the desired volume of purified water.

Water purification system and method including dispensed volume sensing and control

A filter assembly for a water purifying apparatus including a plurality of cartridges. Each cartridge includes first and second ends and an interior volume containing a filtering medium. A plurality of end caps are respectively connected with the first ends of the plurality of cartridges and each end cap includes a water inlet and a water outlet. A removable manifold is coupled with the water inlets and water outlets and the manifold includes a pair of auxiliary ports. One auxiliary port directs water from the cartridge assembly to an auxiliary processing device and another auxiliary port directs the water from the auxiliary processing device back to the filter assembly. The water inlets and water outlets extend generally parallel to a longitudinal axis of each cartridge. The cartridge includes an outer tubular member in fluid communication with the water inlet and an inner tubular member in fluid communication with the water outlet. The inner tubular member has a first end connected in a sliding manner to the first end cap and a second end rigidly affixed to the second end cap.

Water purifying apparatus and method for purifying water

Liquid filter cartridge pack

A manually operable fluid dispensing system having a fluid dispenser connected to a fluid source by flexible tubing. The dispensing system provides a supply fluid path from the source of fluid to the dispenser and a recirculation fluid path from the dispenser to the source of fluid. A dispenser mount is rigidly attached to a support surface for releasably holding the dispenser, and the dispenser mount supports the dispenser in a fixed position for dispensing fluid therefrom. In addition, the dispenser can be removed from the mount for dispensing fluid at a remote location. A manually operable trigger is pivotally connected to the dispensing valve and has a quiescent position which closes the dispensing valve. When in the quiescent position, a trigger handle extends over an exterior portion of the dispenser body in a generally forward direction toward the dispensing outlet and forms an included angle with the dispenser body. The trigger is movable toward the dispenser body to open the dispensing valve, thereby permitting fluid to flow through the dispensing outlet. A spring biases the trigger handle toward its quiescent position, thereby closing the dispensing valve and stopping the flow of fluid through the dispensing outlet.

Fluid dispensing system

A water purifier which produces ultrapure water from a variety of feed sources. The feed source water may be potable tap, distilled, deionized, or water treated by reverse osmosis. The water is passed through a first purification media (30) and then through a chamber (34) where it is exposed to ultraviolet light in the presence of titanium dioxide. The water is then passed through a second purification media (38) to a dispensing valve (40). Operating the dispensing valve (40) provides ultrapure water from the purifier having a specific resistance of at least 18.0 megohm-cm and a TOC count of less than one ppb.

Water purifier

A dispenser (20), including a plunger (24) and cylinder (26) connected to a dispenser body (28), a flow control valve (54) is rotatably mounted in the dispenser body (28) and has a valve fluid path (92, 106, 108) connected between the cylinder (26) and a control valve outlet (109). Advancing the plunger (24) when the valve (54) is in a first, recirculate position pushes liquid from the cylinder (26), through a return path (112) and back into the bottle (22). Advancing the plunger (24) when the flow control valve (54) is in a second, dispense position delivers liquid from the cylinder (26) out through a dispensing orifice (120).

Bottle top dispenser

Fluid dispenser

A water purifier for supplying high purity water with a low total organic carbon content. The purifier includes removable cartridges that contain a series of organic and ion exchange purification media. Special couplings are used to permit the cartridges to be easily and quickly connected to and removed from the water purifier. In addition, the cartridges contain a check valve to minimize water drainage from the cartridge when the cartridge is removed. Selected water purifier components are constructed of fluorinated polyethylene.
