Filed:

Aug 2, 2006

Appl. No.:

11/497764

Inventors:

Masao Kondo - Dublin OH, US

Assignee:

Geyser Pump Tech. Co. - Dublin OH

International Classification:

B01D 3/04

US Classification:

210151, 210220

Abstract:

A system reduces ammonia within a fluid flow. The system includes an aeration vessel, a clarifier vessel, and a geyser pump. The aeration vessel nitrifies bacteria within the fluid flow. The aeration vessel has an intake flow rate. The clarifier vessel receives fluid from the aeration vessel. The geyser pump transfers activated sludge from the clarifier vessel to the aeration vessel. The geyser pump transfers activated sludge at a specific flow rate. The specific flow rate is less than 150% of the intake flow rate.

Inventors:

Masao Kondo - Cary NC

Assignee:

NCA2BioProcess, Inc. - Raleigh NC

International Classification:

F04F 1924

US Classification:

417 54

Abstract:

An airlift pump apparatus and method is based on the practice of injecting air intermittently into a vertical riser tube at a location above a bottom open end of the riser tube which is submerged in the liquid to be pumped. The intermittently injected air is used to create intermittent airlifts within the tube and cause aerated liquid to be discharged intermittently from an output port of the tube.
