  • Patent number: 4830746
    Abstract: An apparatus for continuously separating intermixed solids and liquids from industrial waste. The device includes an elongated conduit having an inlet and outlet and where the interior of the conduit forms a mixing chamber. The industrial waste is pumped into the inlet of the mixing chamber and a polyelectrolyte compound is introduced into the mixing chamber at at least two spaced locations along the conduit. The outlet of the conduit is then passed across both a stationary screen and then into a rotating drum separator, which, together, remove the water from the waste material.
