A water filter having a housing having a water inlet and a water outlet on a first end, and a pair of replaceable carbon elements contained within the housing, each carbon element having a water inlet near an outside diameter and a water outlet near the center, both the water outlet and water inlet being on a first end of each carbon element and each of the carbon element inlets being in fluid communication with the housing water inlet and each of the carbon element outlets being in fluid communication with the housing water outlet.

An expandable water filtering pitcher having a pitcher with a top portion, a base portion and an inner wall surface defining an internal volume of the pitcher, a spout at the top portion at a pitcher opening, a handle attached to an exterior of the pitcher, a filter adapter mounted within the pitcher top portion. The filter adapter is within a reservoir comprising an opening therethrough from the top portion to the base portion of the pitcher and a reservoir sleeve movably coupled to the reservoir and top portion, at least one of the reservoir and the reservoir sleeve moveable in relation to the other between a retracted position defining a first reservoir volume within the reservoir and reservoir sleeve, and an expanded position defining a second reservoir volume within the reservoir and reservoir sleeve at least 40% larger than the first reservoir volume.

A medicament preparation system, according to an embodiment, includes a water purification module and a medicament proportioning module. The system is configured to allow convenient and safe use in a home environment or a critical care environment as well as others affording safety, reliability, and a compact form factor.

Water treatment and valve control systems and apparatuses, and methods of using the same, are disclosed. In some examples, the apparatuses, systems, and methods include use of a rotary position sensor and one or more rotatable elements configured to, when moving from an initial rotational position to subsequent rotational positions, move one or more element of a valve assembly. In various examples of the apparatuses, systems, and methods, the rotatable element rotates directly from one rotational position to another rotational position. In certain examples, the rotary position sensor measures an electrical resistance value to detect the rotational position of the rotatable element.

A water filtration housing containing a pressure vessel configured to receive a water filter cartridge; a ring enclosure attachable to an open, top end of the housing enclosure; an interface tower including a user interface; a lid assembly removably attachable to the ring enclosure, the lid assembly including (i) a pressure cap and gasket for maintaining a given pressure in said pressure vessel and (ii) a rotatable lever for disengaging the pressure cap from the pressure vessel thereby releasing pressure therein. A mating system between the lid assembly and ring enclosure prevents the lid assembly from being attached to the ring enclosure in a misaligned fashion. RFID technology may be used for identifying the water filter cartridge installed therein and wireless communication technology (e.g., Wi-Fi) to transmit collected system data (e.g., water usage) to a central location for analysis such that the customer is provided with, for example, operational suggestions.

A medicament preparation system includes a water purification module and a medicament proportioning module that is interoperable with a replaceable fluid circuit. The fluid circuit includes a purified water inlet, a product medicament outlet, and a plurality of pumping tube segments. At least a first concentrate container is connected by at least a portion of the fluid circuit to the product medicament output and a first concentration measurement sensor station is positioned in a flow path. A controller is programmed to calculate iteratively a concentration of a first concentrate from the first concentrate container and the purified water from a signal generated by the first concentration measurement sensor station and to regulate one or both of a first pumping actuator engaged with the first pumping tube segment and a second pumping actuator engaged with the second pumping tube segment, responsively to the concentration of the first concentrate and water.

A water treatment system includes a water tank, a water filtration media, and an ozone gas source. A control system operates a service mode of the water treatment system during which an external water source is filtered by the filtration media. The control system also operates a regeneration mode of the water treatment system for regenerating the filtration media. The regeneration mode includes a first backwash mode to backwash the filtration media with the external water source. The regeneration mode includes a draw mode subsequent to the first backwash mode to draw ozone into the water tank and into contact with the filtration media. The regeneration mode includes a second backwash mode subsequent to the draw mode to expel ozone from the water tank and the filtration media prior to switching the system back into the service mode for filtration of the water source with the regenerated filtration media.

A system for providing treated water includes a water treatment unit including an inlet water quality probe, a worker bed, a probe to measure a parameter of water from the worker bed, a polisher bed connected downstream from the worker bed and having a probe to measure a parameter of water from the polisher bed, and a flow meter upstream of the worker bed or downstream of the polisher bed. A controller in communication with the flow meter and the probes is configured to receive data from same. A remote server in communication with the local water treatment unit is configured to receive data from the local water treatment unit. The controller or the server may determine a cumulative flow total, a billing cycle flow total, a current exchange flow total, a contaminant load, or a remaining capacity of the water treatment unit.

A water production system with a thermal separation device that defines a cold region and a hot region, a fluid-air heat exchanger located remotely from the thermal separation device and exposed to air, and a fluid circulation loop that thermally connects the cold region of the thermal separation device to the fluid-air heat exchanger so as to cool the fluid-air heat exchanger and condense water from ambient air to produce water pure enough so that with further treatment it can be made potable. Also disclosed are filtration and dispensing features that are appropriate for a potable water supply.
