US Patent:

61714984, Jan 9, 2001

Filed:

Mar 10, 1998

Appl. No.:

9/037694

Inventors:

John J. Fassbender - Suamico WI
Daniel H. Phillips - Hinckley IL
David K. Wyness - Islamorada FL

Assignee:

Chicago Bridge & Iron Company - Plainfield IL

International Classification:

B01D 2126
B01D 2102

US Classification:

2105121

Abstract:

An upflow water clarifier for treating a liquid that contains dissolved or suspended solids has a central pier disposed in the center of a conical section angled at an angle of about 40 degrees to about 60 degrees with respect to the horizontal. Water enters the clarifier at the bottom and is removed at the top. The central pier bears at least part of the weight of an observation deck and includes a mechanism for discharging sludge from the clarifier. The pier can also house both a sludge discharge line and an effluent withdrawal line, and as a support for a radial trough used to collect the effluent. The pier may also serve as an aid during construction.

B01D 2132

US Classification:

210739

Abstract:

A method and apparatus are disclosed which provide enhanced solids-contacting vessel performance in which untreated liquid is injected into a lower portion of the vessel so as to flow in substantially helical and upward directions, solids separating from the untreated liquid into a suspended and rotating sludge blanket. The apparatus includes devices for withdrawing effluent from the vessel from a variety of locations depending upon the flow characteristics of the liquid in the vessel. The apparatus may include a radial weir trough that can be moved vertically within the vessel.
