The present invention discloses systems and methods for purifying non-potable water. For some embodiments, the system comprises a chemical filter placed at an outlet where potable water exits the system.

An adapter (9) for connecting a removable liquid container (10) to a liquid dispenser (1), said adapter having at a first end thereof a liquid container connector and at a second end thereof a dispenser connector, said liquid container connector having a probe part (12) adapted to pierce an outlet comprising a self-sealing valve or membrane of said removable liquid container (10), said probe part (12) being hollow and having at least one inlet for liquid from said removable liquid container, said dispenser connector being hollow and having at its end remote from said probe part an outlet for liquid from said removable liquid container, wherein the outlet of the dispenser connector is adapted to fit tightly around an existing feed tube of the liquid dispenser (1). The adapter (9) can be part of an adapter assembly, which can optionally comprise a liquid transfer regulating means (11) adapted to cooperate with and regulate liquid transfer through said adapter (9).

A delivering device (12) of liquids contained in water crocks is described, equipped with a system or kit (1) for replacing the water crocks with vessels of the Bag-In-Box BIB (14) type for their delivery, such system or kit (1) being adapted to perform the placement and connection of the BIB vessels (14) on the delivering device (12), and comprising: a main body (4, 17, 18); a plate (3, 16) adapted to place thereon at least one BIB vessel (14); a connector (10) and adapted to be connected with a delivering tap of a BIB vessel (14); a plug (8) adapted to be connected to a PIN (13) of the delivering device (12); a connecting tube (4.1, 17.1, 18.1) placed in the main body (4, 17, 18) and connected to the flexible hose (9) for communicating the BIB vessel (14) with the delivering device (12); and a check valve assembly (6, 7) for preventing liquid from reentering into the main body (4, 17, 18).

A spike for dispensing fluids from a flexible bag, wherein the spike includes multiple fluid channels which transfer liquids from the bag to an enclosed dispensing chamber and air from the enclosed chamber to the bag to permit and control fluid flow within the system.

A removable liquid transport assembly configured to be readily installed in and removed from a liquid dispenser to permit the liquid dispenser to be readily sanitized. The removable liquid transport assembly preferably includes a liquid manifold, a valve assembly and a pump head. The removable liquid transport assembly is configured such that liquid can flow in a first direction through the removable liquid transport assembly to permit a liquid to be dispensed from a liquid dispenser and liquid can flow in a second direction back to a liquid storage container to prevent damage to one or more components of the liquid dispenser.

A tank refilling system is configured to keep liquid in a destination tank close to a predetermined destination tank fill line. The tank refilling system has a source tank connected to a destination tank with a flow through secondary process therebetween. Liquid flows between the tanks by gravity fed drainage. A single liquid supply channel to transfer pressurized supply liquid is comprised of a plurality of piping segments and one or more valves, all connected in series. A source tank mounted valve is configured to permit liquid to flow until the height of liquid level in the source tank reaches a predetermined level. A destination tank mounted valve is configured to permit liquid to flow until the height of liquid level in the destination tank reaches a predetermined level. The apparatus of the invention also prevents tank overflow for both the source tank and the destination tank.

Water containers and dispensers with built-in water cooling systems are provided herein. An example water dispenser includes a base, a vertical sidewall extending upwards and around an outer edge of the base, a chamber being formed by the base and the vertical sidewall, a neck extending upwards from an upper portion of the vertical sidewall, a dispensing mechanism coupled to the vertical sidewall, a vapor-compression refrigeration system coupled to the base or the vertical sidewall, an electrical connector interface coupled to the vertical sidewall, a detachable bottle, and a bowl connected to the vertical sidewall and positioned beneath the dispensing mechanism. Another example water dispenser includes a thermoelectric cooling system in addition to, or in lieu of, the vapor-compression refrigeration system.

The water cooler includes a base, a lower housing supported on the base with a cooling tank therein. A tray tank is supported on the lower housing and has a draft surfaces leading to a tray tank outlet. An outer tank with a lower opening is in fluid communication with the draft surface of the tray tank. An upper opening of the outer tank supports an inner tank with the inner tank nested within the outer tank. The inner tank has a top opening for receiving water and a bottom opening with a filter. A lid covers the openings of both the outer tank and the inner tank. The cooling tank has a cooling tank inlet for receiving water from the tray tank outlet, a cooling tank outlet connected to a spigot outside of the lower housing, an air relief tube, and a cooling mechanism attached to the cooling tank to cool water therein.

A removable liquid transport assembly configured to be readily installed in and removed from a liquid dispenser to permit the liquid dispenser to be readily sanitized. The removable liquid transport assembly preferably includes a liquid manifold, a valve assembly and a pump head. The removable liquid transport assembly is configured such that liquid can flow in a first direction through the removable liquid transport assembly to permit a liquid to be dispensed from a liquid dispenser and liquid can flow in a second direction back to a liquid storage container to prevent damage to one or more components of the liquid dispenser.

A water-dispensing device includes a cold water tank and a fill valve. The tank is in selective fluid communication with a water intake via the fill valve. The device further includes a cold dispensing valve, a spigot in selective fluid communication with the tank via the cold dispensing valve, an ozone generator in fluid communication with the tank, and a drip tray positioned beneath the spigot. The drip tray is in fluid communication with a drain via a drain hose. A controller is configured to perform a cleaning operation by: (i) activating the ozone generator to ozonate water stored in the tank, (ii) opening the cold dispensing valve to empty the tank by dispensing the ozonated water from the tank through the spigot and into the drip tray, and (iii) upon determining the tank is empty, opening the fill valve to refill the tank.
