  • Patent number: 9630858
    Abstract: A method for treating ballast water to achieve IMO standards for ballast water includes a reactor fabricated of copper nickel for receiving and discharging ballast water, a UV source for irradiating the water in the presence of copper nickel thereby to generate free radicals for biocidal and bactericidal effects on organisms and microbes entering the reactor with ballast water.
    Type: Grant
    Filed: May 6, 2016
    Date of Patent: April 25, 2017
    Inventors: Halvor Nilsen, Birgir Nilsen

  • Patent number: 7166230
    Abstract: A device (1) for separating and filtering particles and organisms from a high volume flowing liquid operating under low pressure. The device (1) includes a conical or cylindrical shape inlet chamber (3) were liquids enter tangentially creating a circular flow without creating a vortex, the liquids accelerate into a separation and filter chamber (14) where the liquids spin around a longitudinally disposed filter element (11) in the center of the chamber (14), with the centrifugal forces separating out larger and heavier particles towards the perimeter of the separation and filter chamber (14), and where smaller particles having a specific gravity closer to that of the liquid are filtered when the liquid penetrates through the filter element wall into the center of the filter element and flows out one of the longitudinal outlets of the unit. Ultraviolet light irreparably damages bacteria, microorganisms and pathogens contained in processed ballast water and may be incorporated as part of the system.
