  • Microbubble injector
    Patent number: 4556523
    Abstract: In a microbubble injector usable to separate materials of different density by flotation, a deflector wall deflects radially a flow of water exiting under pressure from an injector hole and containing dissolved air at the saturation concentration. This procures cavitation which is localized at the edges of the hole and which generates the required microbubbles of air downflow thereof.
    Type: Grant

  • Method of degassing a liquid
    Patent number: 4534774
    Abstract: The concentration of air in water is rapidly reduced by 80% in a separation enclosure (28) at reduced pressure by virtue of prior injection of microbubbles of air into the enclosure (26). Degassed water is useful for scaling cavitation effects in a hydraulic test tunnel.
