  • Apparatus for filtering liquids containing particles
    Patent number: 5685983
    Abstract: An apparatus for filtering liquids, such as fiber suspensions or polluted water, includes a hollow rotating filter body adapted to receive the liquid to be filtered within the body. A plurality of guide members are attached to the filter body and distributed around the latter to receive cloudy filtrate penetrating the filter body at the descending side. A basin is arranged at the descending side of the filter body to collect cloudy filtrate poured from the guide members. As a result, the cloudy filtrate is prevented from mixing with the clear filtrate.
