  • Patent number: 11884561
    Abstract: A device for removing chloride-containing salts from water includes a container configured to contain saline water, a first electrode arranged in fluid communication with the saline water, and a power source. The first electrode includes a conversion material that is substantially insoluble in the saline water and has a composition that includes at least two or more of aluminum, chlorine, copper, iron, oxygen, and potassium. The composition varies over a range with respect to a quantity of chloride ions per formula unit. The power source supplies current to the first electrode in a first operating state so as to induce a reversible conversion reaction in which the conversion material bonds to the chloride ions in the saline water to generate a treated water solution. The conversion material dissociates the chloride ions therefrom into the saline water solution in a second operating state to generate a wastewater solution.

  • Patent number: 11884560
    Abstract: A water softening device includes a container configured to contain water, first and second electrodes arranged in fluid communication with the water, and a power source. The first electrode includes a conversion material that has a first composition and a second composition coexisting with the first composition. The first composition includes calcium ions bonded thereto and the second composition includes sodium ions bonded thereto. The power source supplies current in a first operating state such that the second composition exchanges sodium ions for calcium ions in the water to generate a soft water solution. The first and second electrodes are connected in a second operating state such that the first composition exchanges calcium ions for sodium ions in the water to generate a wastewater solution. The conversion material undergoes a reversible conversion reaction to convert between the first and second compositions within the water stability window.

The first and second electrodes are configured to be arranged in fluid communication with the saline water solution. The power source is configured to supply electric current to the first and second electrodes in different operating states to induce a reversible intercalation reaction within the intercalation compound. The intercalation compound reversibly stores and releases target anions from the saline water solution to generate a fresh water solution in one operating state and a wastewater solution in another operating state.

The AEM has a continuous porous structure and a plurality of negatively-charged oxygen functional groups coupled to the porous structure. The power source is configured to selectively apply a voltage to one of the first and second electrodes. The AEM has a selective permeability when the voltage is applied such that cations in the saline water solution have a first diffusion rate d1 therethrough and anions in the saline water solution have a second diffusion rate d2 therethrough. The first diffusion rate d1 is less than the second diffusion rate d2 and greater than or equal to zero.
