A system and a method for desalination of water is provided. The desalination system includes an ultrasonic chamber to store saline water, an ultrasonic transducer disposed within the ultrasonic chamber, and a collection chamber coupled to the ultrasonic chamber. The ultrasonic transducer generates an aerosol including water particles from the saline water. A vertical distance between a lower region and an upper region of the ultrasonic chamber is above a pre-determined threshold value so that an average size of the water particles of the aerosol is reduced by gravity to 5 m or less. A fan is provided to transfer the aerosol from the upper region of the ultrasonic chamber to the collection chamber. The collection chamber is configured such that the water particles in the aerosol condense to form liquid water in the collection chamber, which has a lower salt concentration than the saline water.

A method of removing contaminants from a solution comprises passing a solution including one or more contaminants through a first cell comprising a first anode chamber and a first cathode chamber, passing a slurry comprising a flowing electrode material through the first anode chamber and the first cathode chamber while applying an electric potential between the first anode chamber and the first cathode chamber to transport anions from the solution to the first anode chamber and to transport cations from the solution to the first cathode chamber, the flowing electrode material comprising a MXene material, wherein M is a metal and X is one or both of carbon and nitrogen, and passing the slurry through a second cell to desorb the anions and cations from the flowing electrode material. Related systems for removing contaminants from a solution, and related methods are disclosed.

A valve body for a water softener system includes a controller, a seal assembly, and a reciprocating piston driven by a drive mechanism. The controller sends signals to the drive mechanism which moves the piston into various positions. The piston cooperates with the seal assembly to direct the flow of liquid through various flow paths, allowing for water softening and regeneration. During regeneration, a regenerant mixture is directed to flow through a resin bed. The valve body is configurable to perform the regeneration process either through a down-flow configuration, wherein a removable filter is coupled to the valve body in a first orientation and a removable brine injector is installed in a first orifice in the valve body or through an up-flow configuration wherein the removable filter is in a second orientation and the removable brine injector is installed in a second orifice.

The present invention relates to a water filter cartridge, with a housing and a flow path for air for ventilating a water tank storing water to be processed by the water filter cartridge. The latter is distinguished in that the flow path has a first water barrier.

Methods and systems of destroying PFAS utilize a jacketed reactor for supercritical water oxidation (SCWO). Inside the jacket, fuel and an oxidant are combined to provide heat for startup and operation of the SCWO reactor. The jacketed reactors can be operated in parallel and in mobile systems that can fit in a trailer for transportation and operation at a site that has PFAS contaminated water.

A water treatment apparatus is disclosed. The water treatment apparatus, according to one embodiment of the present invention, may comprise: a filter unit comprising a reverse osmosis filter for supplying purified water filtered from raw water, and residential water which could not be filtered from raw water; a storage unit connected to the filter unit and comprising a storage member in which purified water is stored, then discharged, and a housing within which the storage member is provided, and through which residential water inflows and outflows; and a flow path changing valve connected to the filter unit and the storage unit, and which allows residential water to outflow from the housing as purified water is stored in the storage member, or allows purified water to be discharged from the storage member as residential water inflows into the housing.

A pet water fountain is described comprising a bowl for holding an aqueous drinking fluid. The pet water fountain includes a housing configured to cover a portion of the bowl and have a fluid reservoir. The pet water fountain includes a rotatable cone positioned within the housing, the cone tapering outwardly from a bottom end to a top end, the bone bottom end having a fluid inlet to allow the passage of fluid from the bowl through the inlet and into the interior of the conde, the cone top end being in fluid communication with the housing fluid reservoir. The pet water fountain includes a filter ring coupled to the cone top end, the filter ring having an exterior housing and a filter media positioned within the exterior housing, and an electric motor coupled to the rotatable cone for rotatably driving the rotatable cone.

The present invention relates to a spiral wound membrane element designs that utilize entrance and exit points in the feed space channel and utilize barriers on the perimeter of the feed space as well as barriers in the feed space area to direct fluid flow in the membrane element.

A treatment system including an influent pump to pump influent fluid stream containing PFAS into the system. The system may include a flow recirculation system including a fluid circuit through which a recirculating fluid stream flows, an electrochemical (EC) reactor comprising at least one pair of electrodes. When the EC reactor is in a first operational mode, a current generated between the anode electrode and the cathode electrode destroys at least some of the PFAS. The system may include a foam management system to reduce an amount of foam in a container of the EC reactor. The system may include a chemical management system to inject a chemical into the recirculating fluid stream. The system may include a temperature control system to regulate a temperature of the recirculating fluid stream. The system may include a recirculation pump to pump the recirculating fluid stream through the flow recirculation system.

Embodiments of the present invention provide the integration of arbitrary flow directing patterns, deposited or integrated on or into the porous permeate spacer in a spiral-wound membrane separation element.
