Abstract
A sealed centrifugal clarifier with a pre-sterilized and disposable container which lines the separation chamber is disclosed. More particularly, the centrifugal clarifier contains a feed port that allows a liquid-solid mixture to be continuously fed into the device wherein the solid is sedimented by rotation of the separation chamber and the clarified liquid is released into an outside receptacle through an effluent port. The throughput rate of the clarifier is adjustable and can be determined as a function of the fill radius of the separation chamber.
Claims41
A centrifugal clarifier comprising:
- a cylindrical separation chamber that is attachable to a drive motor;
- an annular lid which attaches to the top of the separation chamber;
- a sterile, disposable container which fits into said separation chamber;
- a disposable lid which attaches to the top of the disposable container;
- a feed port which passes through the disposable lid and is capable of passing a liquid or a liquid-solid mixture from an outside source into the disposable chamber;
- and
- an effluent port which passes through the lid and is capable of passing a liquid from the disposable container into an outside receptacle;
- wherein the feed port is connected to a feed tube which runs along the longitudinal axis of the separation chamber and carries liquid or a liquid-solid mixture from the feed port to the disposable container and wherein the effluent port is connected to a effluent tube which runs along the longitudinal axis of the separation chamber and carries liquid from the disposable container to the effluent port;
- openings positioned in the wall of the effluent tube so that liquid from the disposable container may pass through the wall of the effluent tube into the interior space of the effluent tube;
- wherein the feed port and effluent port are structured and arranged to allow continuous flow into and out of the disposable container;
- wherein the liquid-solid mixture is fed into the disposable container through the feed port;
- wherein the separation chamber can spin around the longitudinal axis of the separation chamber so that the liquid-solid mixture fills the disposable container from the radially most outward bottom portion of the disposable container upwards and inwards to the topmost center portion of the disposable container;
- wherein the solid is separated from the liquid-solid mixture due to the centrifugal force of the rotating separation chamber until the disposable container is almost filled with the separated solid;
- and
- wherein the clarified liquid is released from the disposable container through the effluent port.

- and
- a membrane core having the effluent tube and feed tube concentrically located therein, whereby liquid passed from the disposable container into the effluent tube first passes through the membrane core;
- wherein the feed tube and effluent tube are structured and arranged to allow continuous flow into and out of the disposable container;
- wherein the separation chamber can spin around the longitudinal axis of the separation chamber;
- wherein components of the liquid or liquid-solid mixture fed into the disposable container are separated due to the centrifugal force of the rotating separation chamber;
- wherein clarified liquid is released from the disposable container through the effluent tube.
