Filed:

Apr 30, 2002

Appl. No.:

10/135118

Inventors:

Juan Carlos Josse - Capistrano Beach CA
John William Sutherlin - New Orleans LA

Assignee:

International Waste Management Systems - London

International Classification:

C02F 330

US Classification:

210605, 210616, 210621, 210631, 210903, 210906, 71 15, 71 21

Abstract:

A process is provided for full treatment of animal manure and other organic slurries containing suspended solids, and dissolved organic matter, nitrogen, and phosphorus, without the need for anaerobic digestion or anaerobic stabilization lagoons. The process includes: centrifugal decanting, flocculation, dissolved air flotation thickening, centrate heating, acidification in fluidized bed reactor, biological removal of phosphorus, nitrogen and dissolved organic matter in microfiltration membrane bioreactor and disinfection with ultraviolet radiation. The process separates liquids from solids, converts solids into organo-mineral fertilizer pellets, and treats the liquid to dischargeable standards. Land application for effluent disposal is not required because the treatment removes all nutrients.

Appl. No.:

10/125282

Inventors:

Juan Josse - Capistrano Beach CA, US
John Sutherlin - New Orleans LA, US

International Classification:

B01D033/70

US Classification:

210/151000

Abstract:

A biological fluidized bed apparatus for the treatment of wastewater comprises: a reactor tank having a conical bottom with angles ranging from about 30 to about 80 degrees, and most preferably about 60 degrees from a horizontal plane; an inert media bed within said tank; and a recirculation pipe within said tank having an upper inlet, and a lower conformed outlet fitting within said media. The apparatus is self-contained, and offers easy and uniform expansion for various types of commercially available media. Besides the biological treatment accomplished within the fluidized bed, this reactor provides mechanical solids/gas/liquid separation and upflow sludge blanket clarification to improve effluent quality. Preferred additional features of the apparatus include a rotating surface skimmer and an excess sludge collection and thickening device powered by an externally mounted drive. With this reactor configuration, anaerobic and anoxic biological treatment and subsequent clarification are achieved in a single enclosed tank.

US Classification:

210151, 210188, 2101953, 210262, 210617

Abstract:

A pre-fabricated, self-contained biological fluidized bed apparatus for the treatment of wastewater, which offers easy and uniform expansion for various types of commercially available media, by means of a conical bottom and a single, non-clogging flow distribution pipe. Besides the biological treatment accomplished within the fluidized bed, this reactor provides mechanical solids/gas/liquid separation and upflow sludge blanket clarification to improve effluent quality. Additional unique features of this apparatus are a rotating surface skimmer and an excess sludge collection and thickening device powered by an externally mounted drive. With this reactor configuration, anaerobic and anoxic biological treatment and subsequent clarification are achieved in a single enclosed tank.
