  • Water filtration device
    Patent number: 5273665
    Abstract: The water filtration apparatus is based on the principles of swirl-separation, flow-straightening and biological filtration. The waste stream is introduced into a swirl chamber. Overflow from the swirl chamber is introduced into a biological chamber in the form of a vertically-oriented tube bundle, where it is straightened, its velocity is reduced and it is allowed to contact a biologically active media. The overflow from the tube bundle is then removed. Underflow is removed from the bottom of the swirl chamber.
