  • Patent number: 8920615
    Abstract: A salt water chlorinator (30) for a swimming pool includes an electrolysis cell having two anodes (98) and a cathode (94). Two scrapers (102), each of which is of titanium and includes scraping portions in the form of ribs (106) in contact with the opposite surfaces of the cathode, are reciprocated relative to the cathode (94) to remove scale deposits from the cathode (94). The scrapers (102) are mounted in a frame (110) and their scraping ribs (106) are curved such that the ribs (106) are self-biased against the cathode surfaces. A mechanism for reciprocating the scrapers (102) includes two solenoid coils (116) which act on cores (114) in a stem (112) of the frame (110). A control circuit for the electrolysis cell is contained in a housing (86) which is attached to a housing (82) for the electrolysis cell. The control circuit includes a flow sensor for sensing salt-water flow through the electrolysis cell.

  • Publication number: 20140339099
    Abstract: A method of producing an apparatus to remove ions from water is disclosed, wherein the apparatus includes a first electrode having a first current collector, a second electrode having a second current collector, and a spacer between the first and second electrodes to allow water to flow in between the electrodes. The method includes flushing water through the spacer and subsequently exerting a force on the stack so as to compress the first and second electrodes and the spacer. Exerting a force on the stack may result in a pressure of less than 5 bar, less than 2 bar, or between 1 bar and 0.5 bar, between the electrodes and the spacer.

    Abstract: Provided are electrochemical devices that are rechargeable, where the regeneration techniques are based on a batchwise application of current or current density to the cells, where there are a service mode where no current or current density is applied and a recharge mode where a current or current density is applied. Electrochemical and EDI systems according to the embodiments herein are suitable for deionization and/or purification of typical municipal tap quality water in applications where demand for purified, low-TDS water is intermittent. Such operations avoid the use of chemical additions for regeneration purposes. In addition the cells provided herein are amenable to small footprints for consumer and commercial applications such as: dishwashers, washing machines, coffee and espresso makers, ice makers, steam tables, car wash water sources, and steamers.
