ABSTRACT:
Apparatus for purifying a liquid containing suspended solids comprising a walled vessel which is closed at the bottom and side and has an upper circular horizontal portion thereby defining a chamber; a conduit for feeding a liquid containing suspended solids to the chamber so that the liquid flows in a helical path upwardly in the chamber to the vessel upper portion; a liquid effluent clarifying and withdrawing device, at the upper portion of the vessel, into which liquid flowing at and adjacent the liquid surface in one direction of a circular path can substantially change direction whereby flow of the suspended solids in the circular path is maintained to a substantially greater extent than the amount of solids carried along with the liquid which changes direction thereby providing a stream of clarified liquid at the withdrawing device; and an outlet into which the stream of clarified liquid can flow from the withdrawing device and be removed from the vessel.
