US Patent:

6845336, Jan 18, 2005

Filed:

Jun 25, 2002

Appl. No.:

10/179436

Inventors:

Prasad S. Kodukula - Chicago IL, US
Charles R. Stack - Aurora IL, US

International Classification:

G06F 1500

US Classification:

702118, 702188, 702104, 702 91, 702 50, 700 48, 700 51, 700 67, 706 6, 706 15

Abstract:

A computer system linked by the internet to various remote waste water treatment facilities. The system receives real-time data from the facilities and analyzing the data to determine likely operational upsets and future effluent water quality. The computer system sends signals to a hierarchy of parties depending on the severity of predicted upsets problems and events. The computer also provides a probability distribution of such upsets and water quality and recommendations as how to adjust facility operating parameters to avoid or reduce the upsets to acceptable parameters and maintain effluent water quality parameters within preselected limits.

Filed:

May 11, 2006

Appl. No.:

11/432605

Inventors:

Prasad Kodukula - Chicago IL, US
Charles Stack - Aurora IL, US

International Classification:

C12Q 1/26
C12Q 1/04
G06F 19/00

US Classification:

435025000, 435034000, 702019000

Abstract:

A process provides for testing for certain toxins and poisons in liquids, gases and solids that are consumed by humans or otherwise come in contact with humans. In the process, the material to be tested is mixed with aerobic microorganisms in a biomass to form a mixture. The mixture is observed to determine if a preselected change in the biomass occurs. Preferably, the mixture is observed to determine if the biomass has a normal rate of respiration.

Appl. No.:

12/661002

Inventors:

Prasad S. Kodukula - Chicago IL, US
Charles R. Stack - Aurora IL, US

International Classification:

C12P 5/02
C12M 1/00

US Classification:

435167, 4352921

Abstract:

A process and apparatus for sequestering carbon and converting it to fuel, such as methane, and/or materials, such as fermentation substrates, biopolymers, bioplastics, oils, pigments, biochar, metals, such as mercury, chromium and arsenic, fibers, proteins, vitamins, fertilizers and animal feed. The apparatus comprises a deep well carbon-sequestering bioreactor coaxially located within a deep well anaerobic bioreactor. Carbon is sequestered into a photosynthetic biomass or a heterotrophic biomass, which is subsequently digested by an anaerobic biomass containing methanogenic microbes, whereby methane is a digestion product. Alternatively, the biomass can be subjected to physical-chemical treatment to produce oil and other useful byproducts.
