US Patent:

43917038, Jul 5, 1983

Filed:

Apr 6, 1982

Appl. No.:

6/365889

Inventors:

Gary A. Crosby - New Iberia LA

Assignee:

Red Fox Industries, Inc. - New Iberia LA

International Classification:

C02F 310

US Classification:

210151

Abstract:

The present disclosure is directed to a sewage disposal system having a central aeration chamber flanked on each side by a pair of biological filters each containing tiers of buoyant plastic hollow spheres through and over which the liquid from the aeration chamber flows upwardly and the filters are connected at the top by a crossover pipe positioned below the top level of sludge in the aeration chamber. The crossover pipe communicates with a vertical riser which functions with a vertical antisyphon vent. The riser communicates with a flexible hose which connects the primary central aeration chamber with the chlorine contact tank to receive the sludge from the biological filters for chlorinating the liquid and providing an adequate retention time for disinfection prior to discharge overboard.

Appl. No.:

6/220775

Inventors:

Gary A. Crosby - New Iberia LA

Assignee:

Red Fox Industries Inc. - New Iberia LA

International Classification:

C01C 126

US Classification:

210139

Abstract:

The present disclosure is directed to a method and apparatus for reducing eddy currents in a clarifier to restrict sludge from entering the clear water zone of the clarifier by periodically pulsing air to the sludge return line from the bottom of the clarifier to the top of the aeration chamber in a sewage treatment plant of both the land base and marine type.

Assignee:

Red Fox Industries Inc. - New Iberia LA

International Classification:

C02F 320
C02F 322

US Classification:

210202

Abstract:

The present disclosure is directed to a sewage treatment device of the marine type and operates on an extended aeration principle employing an aerator, clarifier and disinfector. The clarifier is disposed beneath the aerator and the top of the clarifier with a common wall therebetween which forms the bottom of the aerator. A first passage conducts fluid from the aerator to the clarifier and has a central port in the common wall. A second passage conducts fluid from the clarifier to the disinfector. The aerator has an influent inlet and the disinfector has an effluent outlet. The treator includes in the aerator vessel nozzle means for admitting air to the vessel in a direction to cause fluid in the vessel to move orbitally about a vertical axis with the nozzle means being disposed at a level proximate the common wall between the aerator and clarifier. The treater also includes a device arranged in a vertical stack of cylindrical components in which the uppermost is an aeration chamber, a clarification chamber beneath the aeration chamber and in communication therewith. A clarifier discharge chamber lies beneath the aeration and clarification chambers, a chlorine contact discharge chamber is connected to the clarifier discharge chamber.
