摘要:
The invention relates to a method for purifying water by dissolving one or more soluble metal salts in the water to provide corresponding metal ions, by dissolving hypohalite into the water, and by regulating the residence time, and thus hypohalite concentration in the device using a venturi nozzle disposed between the metal generator and the hypohalite generator.

The invention relates to an apparatus for electrolytic purification, comprising: (a) a pressure vessel having at least one access opening, at least one fluid flow inlet, and at least one fluid flow outlet, wherein the fluid flow inlet and fluid flow outlet are in fluid communication with a chamber inside the pressure vessel; (b) an removable electrode assembly, at least a portion of which is disposed within the chamber inside the pressure vessel, comprising: a plurality of substantially parallel spaced planar electrodes, an electrical coupling between the electrode plates and a voltage source, and a radially extending circumferential sealing plate substantially normal to the planes of the electrodes, disposed near the electrical coupling, adapted to prevent fluid flow from the chamber to the electrical coupling; (c) a removable locking ring, comprising: a proximal portion adapted to removably attach to the access opening of the pressure vessel and retain the radially extending circumferential sealing plate of the electrode assembly against the pressure vessel access opening.

The invention relates to the control of pH in water where hydroxyl ions are being produced by adding to the water an amount of transition metal salt sufficient to bind with hydroxyl into a slightly soluble or insoluble reaction product, thereby removing sufficient hydroxyl ion from the water to lower the pH thereof. This technique is particularly suitable for pH control in pool or spa water that is sanitized using chemical or electrolytic chlorination, where the sanitation process causes the pH in the water to rise.
