  • Device for chemically/physically treating drinking water
    Patent number: 7294258
    Abstract: The invention relates to a device for physically treating drinking water, in particular, for reducing the formation of limestone. The invention device comprises at least one water inlet (3b) and at least one water outlet (3c), whereby the device is mounted in the cold water supply line (3) of at least one water heater (1), preferably a boiler, and the device is placed in good heal-conductive thermal contact with the hot water area of the water heater (1).
    Type: Grant
    Filed: January 25, 2002
    Date of Patent: November 13, 2007
    Assignee: Watercryst Chemiefreie
    Inventors: Klaus Leiter, Gerhard Walder, Franz Mair

  • Method for precipitating or flocculating substances out of solutions
    Patent number: 6660167
    Abstract: In a method for precipitating or flocculating substances out of a solution, the solution is brought into contact with at least one ion exchange material having a surface provided with functional groups loaded with counter ions. The precipitation or flocculation is effected catalytically without exchange of the counter ions for ions contained in the solution.
