Appl. No.:

6/459343

Richard B. Weber - Denver CO

International Classification:

B01F 304

US Classification:

261 93

Abstract:

A fluid diffuser for dispersing a gas or liquid into a body of receiving liquid in which it is immersed. The diffuser includes a rotatable shaft, a thin disk-like member mounted for rotation on the shaft, and an annular ring positioned adjacent the outer perimeter of the disk-like member. At least one of the top and bottom walls of the annular ring is porous. These top and bottom walls define a fluid plenum, into which gas or liquid under pressure is introduced to be emitted from the plenum as small, nascent fluid spheroids on the surface of the annular ring. The boundary layer flow from rotation of the disk-like member within the body of receiving liquid shears fine gas bubbles or liquid particles from the foraminous surface or surfaces of the annular ring. The annular ring may be fixed, or rotatable in the opposite annular direction from the rotation of the disk. Impeller blades may be mounted on the top and/or bottom surfaces of the rotatable disk.

Abstract:

A diffuser for dispersing gas into a body of liquid that may contain suspended solids. Under ordinary clogging conditions, the diffuser will remain operative over an indefinite period of time by reason of large gas outlet openings at the bottom of the gas plenum chamber. In addition, it can be employed for a good portion of that time to disperse a substantial flow of coarse bubbles and fine bubbles, in a desired combination, simultaneously from a single gas plenum. Careful selection of the permeability and area of a top porous wall of a gas plenum chamber, together with proper selection of the level, size and number of coarse bubble gas outlet openings in the side walls of the plenum chamber, achieve the second feature.

Abstract:

Biological oxidation and flotation apparatus and method are disclosed for use in the treatment of sewage or other aqueous waste material by the activated sludge process. A treatment and flotation chamber is provided in which both biological oxidation and flotation take place. In some forms of the method and apparatus, a separate biological oxidation tank is also used prior to the treatment and flotation chamber. The treatment and flotation chamber includes a quiescent zone at the top of the chamber that extends horizontally through at least the downstream part of the chamber, and extends downward at least about three inches blow the surface of the contents of the chamber. The contents of the chamber below the quiescent zone are continuously recirculated, for example by pumps whose inlets lie below the quiescent zone and which transfer a part of the aqueous material under treatment to the bottom of the chamber to be employed as the shearing liquid in a bubble shearing apparatus. The entire contents of any part of the treatment and flotation chamber over which the quiescent zone does not extend are also continuously recirculated, as are the entire contents of any separate biological oxidation tank. Oxygen-containing gas bubbles are introduced into the system to provide oxygen for biological treatment of the aqueous material in any separate biological oxidation tank and in the treatment and flotation chamber, and to provide bubbles (supplemented by carbon dioxide and nitrogen, absorbed from the liquid medium) which attach themselves to suspended solid particles to form a float in the quiescent zone at the top of the treatment and flotation chamber.

Abstract:

A mixer for mixing a body of receiving liquid with solids, liquids or gases introduced therein. The mixer includes a rotatable shaft, a thin disk-like member mounted for rotation on the shaft, and at least one thin annular ring mounted on the disk-like member spaced from, parallel to and concentric with it. The flow of liquid perpendicular to the annular ring through the inner opening thereof, when the mixer is immersed and rotating in the body of receiving liquid, is unimpeded by any structural member. The annular ring may be mounted on either side of the disk, and a plurality of annular rings may be employed. The annular ring or rings may be mounted on the disk-like member by at least three elongated support posts spaced equally around the outer perimeter of the disk, the transverse cross-section of each post being curvilinear, preferably circular, in shape. The mixer is disclosed for use in a tank. The vertical position of the rotatable disk-like member in the tank produces a flow pattern in the body of receiving liquid that is characteristic of the particular position selected.

Abstract:

An air lift diffuser for use in the aeration of a body of water including an air lift tube and a gas diffuser located a distance below the open bottom end of the air lift tube. The distance in question is sufficiently large that there is substantially no obstruction to the passage of water from the space surrounding the air lift diffuser into the space between the air lift tube and the diffuser, but at the same time is not so large that rising air bubbles are likely to escape and flow outside the air lift tube. In one embodiment, a cylindrical return tube is provided around the air lift tube that directs the water stream and gas bubbles entrained therein downward, after they have risen in the air lift tube, so as to return the aerated water to the lower levels of the body of water being aerated.
