Bacterial Cultivation System For Growth Of Substrate Specific Micro-Organisms For Use In Industrial Wastewater Remediation

View page
US Patent:
8282826, Oct 9, 2012
Filed:
Nov 8, 2011
Appl. No.:
13/291831
Inventors:
Michael Harvey Foster - Mandeville LA,
Kenneth Wayne Smith - Natchez MS,
Bronwyn Duos - Hammond LA,
Elizabeth Claire Guidotti - Mandeville LA,
Assignee:
Environmental Business Specialists, LLC - Mandeville LA
International Classification:
C02F 3/00
US Classification:
210601, 210610, 210611, 210620
Abstract:
A waste treatment method includes the concentration of selected strains of bacteria in a selected medium in the presence of nutrients and water, under aerobic conditions. This concentrated batch is discharged for downstream applications in wastewater remediation. A cultivation chamber having inlet ports and a circular vent port allows for adequate air introduction and heat release. Aeration is achieved by recirculation of the fluid medium from the top of the apparatus through a pipe that runs the length of the inner wall and is specially configured at the top to minimize cell damage. Fluid can be routed tangentially in clockwise and counterclockwise directions. The conical bottom has an orifice allowing for recirculation of the fluid medium tangentially to the sidewalls. Upon completion of the batch cultivation, the medium and bacteria are discharged for downstream applications in wastewater remediation of paper mill, chemical plant, oil refinery, and other industrial effluents.

US Patent:
8052873, Nov 8, 2011
Filed:
Oct 30, 2008
Appl. No.:
12/261883
Inventors:
Michael Harvey Foster - Mandeville LA,
Kenneth Wayne Smith - Natchez MS,
Bronwyn Duos - Hammond LA,
Elizabeth Claire Guidotti - Mandeville LA,
Assignee:
Environmental Business Specialists, LLC - Mandeville LA
International Classification:
C02F 3/00
US Classification:
210610, 210611, 2101951
Abstract:
A waste treatment method includes the concentration of selected strains of bacteria in a selected medium in the presence of nutrients and water, under aerobic conditions. This concentrated batch is thereafter discharged for downstream applications in wastewater remediation. The present invention employs a cultivation chamber having inlet ports and a circular vent port that allows for adequate air introduction and heat release. Aeration is achieved by recirculation of the fluid medium from the top of the apparatus through a pipe that runs the length of the inner wall and is specially configured at the top to minimize cell damage. Fluid can be routed tangentially in both the clockwise and counterclockwise directions within the chamber. The conical bottom also has an orifice allowing for recirculation of the fluid medium tangentially to the sidewalls. Upon completion of the batch cultivation, the medium and bacteria are discharged for downstream applications in wastewater remediation of paper mill, chemical plant, oil refinery, and other industrial effluents.
