US Patent:

56956487, Dec 9, 1997

Filed:

Oct 31, 1995

Appl. No.:

8/550743

Inventors:

John J. Fassbender - Batavia IL
Donald N. Ruehrwein - Batavia IL
Daniel H. Phillips - Hinckley IL

Assignee:

Chicago Bridge & Iron Technical Services Company - Oak Brook IL

International Classification:

B01D 2124
B01D 2130

US Classification:

210739

Abstract:

A method and apparatus are disclosed which provide enhanced solids-contacting vessel performance in a vessel in which untreated liquid is injected into a lower portion of the vessel so as to flow in a substantially helical and upward direct to separate the solids from the liquid in a suspended, rotating sludge blanket. The vessel is equipped with an adjustable weir extending substantially radially form the vessel center to its peripheral wall for withdrawing effluent from the vessel from a variety of locations depending upon the flow velocity characteristics of the liquid in the vessel.

Appl. No.:

9/165939

Inventors:

Donald N. Ruehrwein - Batavia IL
David K. Wyness - Springfiled IL
Daniel H. Phillips - Hinckley IL

Assignee:

Chicago Bridge and Iron Company - Plainfield IL

International Classification:

B01D 2102

US Classification:

210519

Abstract:

An upflow liquid clarifier for treating a liquid that contains dissolved or suspended solids has a lower chamber with an annular shape, an inner wall extending upwardly and inwardly from that lower chamber, and an outer wall that extends upwardly and outwardly from the lower chamber. Inlets in communication with the lower chamber provide entry for liquid, which rises in a helical motion through the clarifier. Motion of the water establishes a sludge blanket, through which clarified water rises and can be removed from near the top of the clarifier. A sludge removal structure allows the continuous or periodic removal of sludge.

US Classification:

210519

Abstract:

An upflow liquid clarifier for treating a liquid that contains dissolved or suspended solids has a lower chamber with two curved ends connected by a straight section, a centrally-disposed dividing wall extending upwardly from that lower chamber, and an outer wall that extends upwardly and outwardly from the lower chamber. Inlets in communication with the lower chamber provide entry for liquid, which rises in a helical motion through the clarifier. Motion of the water establishes a sludge blanket, through which clarified water rises and can be removed from near the top of the clarifier. A sludge removal structure allows the continuous or periodic removal of sludge.
