  • Patent number: 7261823
    Abstract: The method is for treating a liquid or slurry with an ultrasonic energy. A first rotatable member being permeable to a medium and a first vibrating device are provided. The first vibrating device and the first member have a first gap formed therebetween so that the first gap represents a first distance. A guide member aligned with the first member exerts a pressure on the medium. The guide member breaks up fiber flocculation close to the upper surface of the medium. The medium is fed between the first member and the guide member. The first vibrating device generates pulses through the first member to form imploding bubbles in the medium. The bubbles have a critical diameter prior to implosion that is greater than the first distance to prevent the bubbles from growing in the first gap to a size greater than the first distance.

  • Patent number: 6861004
    Abstract: A self-cleaning water filter, coupled to a water flow having particulates therein, that includes a pair of canisters, each having a cylindrical wedge wire water filter screen. An elongated brush running the length of the screen is disposed between two confining walls also running the length of the screen to form a chamber. A elongated partition, including two sets of apertures, is used, along with the elongated brush, to divide the chamber into two particulate dislodge chambers and a drain subchamber. A drain is in fluid communication with the drain subchamber. During cleaning, the drain is opened and the screen is rotated against the brush for liberating the particulate contaminants and a limited amount of the water flow into the two dislodge subchambers. The particulate contaminants and the limited amount of water then pass through the apertures at a high velocity and into the drain subchamber which exits through the drain.
