A process and system for purifying water is disclosed. For example, in one embodiment, the process may be used to remove a divalent salt, such as calcium sulfate, from a water source in order to prevent the divalent salt from precipitating during the process. The water source, for instance, may be fed to an ion separating device, such as an electrodialysis device. In the electrodialysis device, an ion exchange takes place between the divalent salt and another salt, such as a monovalent salt to produce two concentrated salt streams that contain salts having greater solubility in water than the divalent salt. In one embodiment, the two salt streams that are produced may then be combined to precipitate the divalent salt in a controlled manner. During the process, various other components contained within the water feed stream may also be removed from the stream and converted into useful products. In one particular embodiment, the process is configured to receive a byproduct stream from a reverse osmosis process.

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 method and apparatus for electrolytically producing oxidation reduction potential water from aqueous salt solutions for use in disinfection, sterilization, decontamination, wound cleansing. The apparatus includes an electrolysis unit having a three-compartment cell (22) comprising a cathode chamber (18), an anode chamber (16), and a saline solution chamber (20) interposed between the anode and cathod chambers. Two communicating (24, 26) membranes separate the three chambers. The center chamber includes a fluid flow inlet (21a) and outlet (21b) and contains insulative material that ensures direct voltage potential does not travel through the chamber. A supply of water flows through the cathode and anode chambers at the respective sides of the saline chamber. Saline solution flows through the center chamber, either by circulating a pre-prepared aqueous solution containing ionic species, or, alternatively, by circulating pure water or an aqueous solution of, e.g., aqueous hydrogen chloride and ammonium hydroxide, over particulate insulative material coated with a solid electrolyte. Electrical current is provided to the communicating membranes separating the chambers, thus causing an electrolytic reaction that produces both oxidative (positive) and reductive (negative) ORP water.

An autonomous water source (AWS) for extracting water from ambient air and delivering it to a plant to support growth. The system is based on an adsorption-desorption-condensation (ADC) cycle using a sorption material to extract moisture from ambient air and condensing the water vapor driven off from the sorption material by subsequent heating and followed by condensation. Liquid condensate produced in this process on the condenser is collected and delivered by gravity to a plant to reduce thermal stress and to support growth.
