A system for generating potable water from source water contains an enclosed vessel, a heating unit, an air distributor, a condenser, and a collection vessel. A method for generating potable water from source water includes heating ambient air, bubbling heated air through source water producing saturated air, cooling the saturated air producing potable water, and collecting the potable water. A method of removing contaminants from ambient air includes heating ambient air, bubbling the heated air through source water to produce treated air and contaminant rich water, discharging the treated air, and discharging the contaminant rich water.

Systems and methods for generating potable water

Water treatment systems including electrically-driven and pressure-driven separation apparatus configured to produce a first treated water suitable for use as irrigation water and a second treated water suitable for use as potable water from one of brackish water and seawater and methods of operation of same.

Method and system for water treatment

Systems and methods for controlling mixing between one or more fluids are provided. The systems and methods may utilize a vessel comprising one or more zones where the zones are configured to minimize mixing between one or more fluids. Certain systems and methods may utilize a vessel comprising a tortuous flow path. Other systems and methods may utilize a vessel comprising one or more zones.

Devices and methods for storing, processing, and delivering a processed liquid

The methods and systems disclosed here relate to treating water. In certain embodiments, a treatment system comprises an electrochemical water treatment device, a recirculating concentrate stream in fluid communication with the electrochemical water treatment device, a flow control device in fluid communication with a first flow path comprising acidic water and configured to be in fluid communication with the recirculating concentrate stream, and a second flow path comprising feed water and configured to be in fluid communication with the recirculating concentrate stream, and a control system in communication with the flow control device. The treatment system may further comprise a recirculating dilution stream in fluid communication with a second inlet and a second outlet of the electrochemical water treatment device.

Performance enhancement of electrochemical deionization devices by pre-treatment with cation exchange resins

Systems and methods for treating water are provided. The systems and methods may utilize an electrochemical water treatment device comprising ion exchange membranes. In certain systems and methods, a concentrate stream and a dilution stream may be in fluid communication with ion exchange membranes. The ion exchange membranes may be configured to provide a ratio of a pH of the concentrate stream and a pH of the dilution stream to be less than about 1.0. In some instances, the LSI of the concentrate stream may be less than or about 1.0. In certain instances, the electrochemical water treatment device does not require a reverse polarity cycle.

Electrochemical water softening system

An electrically-driven separation apparatus can be utilized to desalinate seawater and/or brackish water to provide irrigation water having a desired sodium adsorption ratio (SAR).

Method and system for irrigation

An electrochemical treating device having low scale potential is disclosed. The device has a variety of configurations directed to the layering of the anionic exchange and cationic exchange. The treatment device can also comprise unevenly sized ion exchange resin beads and/or have at least one compartment that provides a dominating resistance that results in a uniform current distribution throughout the apparatus.

Low scale potential water treatment

A water treatment system provides treated or softened water to a point of use by removing a portion of any hardness-causing species contained in water from a point of entry coming from a water source, such as municipal water, well water, brackish water and water containing foulants. The water treatment system typically treats the water containing at least some undesirable species before delivering the treated water to a point of use. The water treatment system has a reservoir system in line with an electrochemical device such as an electrodeionization device. The water treatment system has a sensor or a set of sensors for measuring at least one property of the water or an operating condition of the treatment system. The water treatment system also has a controller for adjusting or regulating at least one operating parameter of the treatment system or a component of the water treatment system to optimize the operation and performance of the system or components of the system to supply water tailored to quality requirements.

Water treatment system and method

A treatment system provides treated or softened water to a point of use by removing at least a portion of any undesirable species contained in water from a water source. The treatment system can be operated to reduce the likelihood of formation of any scale that can be generated during normal operation of an electrochemical device. The formation of scale in the treatment system, including its wetted components, may be inhibited by reversing or substituting the flowing liquid having hardness-causing species with another liquid having a low tendency to produce scale, such as a low LSI water. Various arrangements of components in the treatment system can be flushed by directing the valves and the pumps of the system to displace liquid having hardness-causing species with a liquid that has little or no tendency to form scale.

A water treatment system provides treated water to a point of use by removing at least a portion of any hardness-causing species contained in water from a water source, such as municipal water, well water, brackish water and water containing foulants. The water treatment system typically receives water from the water source or a point of entry and purifies the water containing at least some undesirable species before delivering the treated water to a point of use. The water treatment system has a pressurized reservoir system in line with an electrochemical device such as an electrodeionization device. The water treatment system can have a controller for adjusting or regulating at least one operating parameter of the treatment system or a component of the water treatment system. The electrochemical device can be operated at a low current and low flow rate to minimize water splitting or polarization, which minimizes scale formation.

A method and apparatus for purifying water are provided. A feed water such as seawater can be fed to a filter such as a microporous or nanofiltration membrane to produce a permeate that can, in turn, be fed to an electrodeionization system to produce fresh water.
