  • Patent number: 10696569
    Abstract: In a system for generating potable water by water desalination using a reverse osmosis filter having a product outlet and a reject outlet, a system for re-mineralization of the potable water comprising two reactors comprising a first reactor and a second reactor, the two reactors configured to be used simultaneously, the first reactor for collecting lime or calcium carbonate from a stream out of the reject outlet in a first cycle, and for dispensing said collected lime or calcium carbonate to a permeate stream out of the product outlet in a second cycle; and the second reactor for dispensing lime or calcium carbonate into the permeate stream-in the first cycle and for collecting lime or calcium carbonate from a stream out of the reject outlet in the second cycle, wherein a DC voltage sufficient to separate the water into hydrogen (H+) ions and hydroxyl (OH?) ions is applied.

  • Patent number: 10077196
    Abstract: A method for solids removal in heat exchanger systems includes a first water flow path from a heat exchanger to a cooling tower and back to the heat exchanger, including: forming an additional path in parallel with the first path, wherein water flows from the heat exchanger to a UET reactor and back to the heat exchanger, and wherein the UET reactor including means for solids removal from the water using a partial electrolysis process. Optionally, the volumetric flow rate in the additional path is about 5% of the volumetric flow rate in the first water flow path.

  • Publication number: 20140183109
    Abstract: In a system for generating potable water by water desalination using a reverse osmosis filter having a product outlet and a reject outlet, a system for re-mineralization of the potable water comprising means for collecting lime or calcium carbonate from a stream out of the reject outlet, and means for adding lime or calcium carbonate to a stream out of the product outlet. The means for collecting lime or calcium carbonate can subsequently be used for adding lime or calcium carbonate to the stream out of the product outlet.

  • Publication number: 20140138258
    Abstract: In a water processing system including a first volume with a raw water inlet and a soft water outlet and a second volume for collecting minerals therein, and wherein mineral ions are transferred to the second volume using an electrolysis process, a method for enhancing minerals removal comprising the steps of transferring water from the second volume to a minerals removal device and using a partial electrolysis process in the minerals removal device to cause minerals to be deposited there. Preferably, the first and second volumes are separated by a membrane.

  • Patent number: 8419925
    Abstract: A method for electrode renewal, for use in an electrolytic processing chamber for a liquid therein wherein the processing includes, for a pair of electrodes in the chamber, placing a positive voltage on one electrode in the chamber and placing a like negative voltage on another electrode in the chamber. It has been common practice to reverse the voltage between these electrodes in order to re-dissolve the buildup thereon. Now, the present inventor has observed that a voltage passing through or across an electrode will cause some minor cavitations on the electrode surface between the contact junctures of the voltage, and apparently the cavitations results in the buildup there-on detaching in bulk; which is much faster than the heretofore known re-dissolve processes of electrode renewal.

  • Publication number: 20120043223
    Abstract: For substantially eliminating scale buildup in a water processing facility, a water treatment method having the steps: accepting a scale formation standard value amount of scale formation that would occur in the facility from a cubic meter of water; measuring water from a water source for total hardness, alkali hardness, pH, and temperature; and therewith substantially removing a calculated scale removal target quantity from each cubic meter of the water source water just prior to entry of said water into the facility. Essentially, just prior to entry of each quantity of predetermined water into a water flow-through processing facility, removing more than about 0.1% of dissolved scale from the water quantity albeit less than 10% of dissolved scale from the water quantity.
