    摘要: Apparatus for treating a liquid containing suspended solids comprising a clarifying vessel and a number of filters positioned around the periphery of the clarifying vessel for receiving and filtering liquid from the clarifier. A filter may be backwashed by isolating that filter, filling the other filter cells with clarified liquid and draining them into the isolated cell to remove filter media contaminants.

    摘要: A method of dissolving a gas in water comprising directing an aqueous stream to rotate in a downwardly moving spiral stream from a high downward velocity to a lower downward velocity and diffusing a gas into the aqueous stream so as to produce small gas bubbles which are rotated in a generally spiral path by the aqueous stream thereby providing a long flow distance over which the bubbles have increased contact time with the aqueous stream to facilitate dissolution of the gas therein and in which rising of the gas bubbles is progressively opposed by the increased downward velocity of the higher portion of the aqueous stream.A vessel for practicing the method can have a vertical axis and be circular in horizontal section for most of its height; have upper and lower ends; include a conical portion with the apex at the upper end of the vessel; have an aqueous stream inlet tangential to the vessel communicating with the vessel interior space near the vessel upper end so that an aqueous stream fed to the vessel through the inlet rotates in a downwardly moving spiral stream from a high downward velocity in the upper portion of the vessel to a lower downward velocity in the lower portion of the vessel; and have a gas diffuser for diffusing a gas into the aqueous stream.

    摘要: A method of and apparatus for treating a liquid containing contaminating solid or dissolved solid materials comprising introducing the liquid into a treatment vessel in the lower part of a generally-conical interior portion thereof, causing said liquid to move upwardly with helical flow through said generally-conical interior portion toward said upper end thereof, the path of said helical flow gradually widening as it progresses upwardly through said generally-conical interior portion thereby resulting in separation of solids from the liquid, gradually decreasing the velocity of said liquid by the gradual widening of said helical flow path as it progresses upwardly to form a rotating sludge blanket of separated solids in the upper part of said generally-conical interior portion above the point of liquid introduction, passing the liquid upwardly through said rotating sludge blanket to clarify said liquid while said liquid is moving along said helical flow path, removing the clarified liquid from said treatment vessel at a location above the level of said rotating sludge blanket, maintaining a central quiescent zone in said treatment vessel at about the mouth of a sludge removal downcomer located at about the position of said rotating sludge blanket, and withdrawing sludge from the rotating sludge blanket through the downcomer mouth.

    摘要: 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.
