Abstract

Systems, methods and media for carbonation of fluid in an algae cultivation pond via the use of jets are disclosed. Carbon dioxide is provided to a pressurized fluid. A jet of carbonated fluid is generated from the pressurized fluid and the carbon dioxide. Circulation of the fluid in the algae cultivation pond is initiated via the jet of carbonated fluid.

Claims

1. A method for initiating carbonation of fluid in an algae cultivation pond, the method comprising:

providing carbon dioxide to a pressurized fluid;

generating a jet of carbonated fluid from the pressurized fluid and the carbon dioxide; and

initiating circulation of the fluid in the algae cultivation pond via the jet of carbonated fluid.

2. The method of claim 1, further comprising dissolving the carbon dioxide in the fluid in the algae cultivation pond at less than a saturation point in the fluid in the algae cultivation pond.

3. The method of claim 1, wherein the jet of carbonated fluid circulates the fluid in the algae cultivation pond at a velocity of twenty centimeters per second.

4. The method of claim 1, further comprising:

measuring a pH of the carbonated fluid; and

adjusting a concentration of carbon dioxide in the jet based on the measured pH.

5. The method of claim 4, wherein measuring the pH includes measuring a pH of a flow of the algae cultivation pond.

6. The method of claim 1, further comprising generating a velocity of fluid flow of at least eight centimeters per second in the algae cultivation pond.

7. The method of claim 6, further comprising providing a head to the jet that overcomes a head loss associated with the velocity of fluid flow of at least eight centimeters per second in the algae cultivation pond.

8. The method of claim 1, further comprising initiating an entrainment of a flow in the algae cultivation pond into the jet of carbonated fluid.

9. The method of claim 8, wherein initiating an entrainment of a flow in the algae cultivation pond via a plurality of vortices.

10. A system for initiating carbonation of fluid in an algae cultivation pond, the system comprising:

a series of nozzles submerged in the algae cultivation pond, the series of nozzles coupled to a source of pressurized fluid and a carbonation source, the series of nozzles configured to;

generate a jet of carbonated fluid from the pressurized fluid and the carbonation source, and

initiate circulation of fluid in the algae cultivation pond via the jet of carbonated fluid; and

a pH sensor configured to measure a pH of the fluid in the algae cultivation pond.

11. The system of claim 10, the system further comprising a manifold coupled to an inlet of the series of nozzles and to the source of pressurized fluid.

12. The system of claim 11, wherein a pressure in the manifold is between four and twenty-five pounds per square inch.

13. The system of claim 10, wherein the source of carbonation is pure carbon dioxide in gaseous form.

14. A system for initiating carbonation of fluid in an algae cultivation pond, the system comprising:

a series of nozzles submerged in the algae cultivation pond, the series of nozzles coupled to a source of pressurized fluid and a carbonation source, the series of nozzles configured to;

generate a jet of carbonated fluid from the source of pressurized fluid and the carbonation source, and

initiate circulation of the fluid in the algae cultivation pond via the jet of carbonated fluid;

a processor; and

a computer-readable storage medium having embodied thereon a program executable by the processor to perform a method for adjusting a concentration of carbon dioxide in the algae cultivation pond, wherein the computer-readable storage medium is coupled to the processor, the processor executing instructions on the computer-readable storage medium to;

measure a pH associated with the carbonated fluid; and

adjust a concentration of carbon dioxide in the jet based on the measured pH.

15. The system of claim 14, wherein the jet of carbonated fluid circulates the fluid in the algae cultivation pond at a velocity of twenty centimeters per second.

16. The system of claim 14, wherein the method executed by the processor further comprises:

initiating a circulation of fluid in the algae cultivation pond via at least one jet, the circulation of fluid generating a velocity of fluid flow of at least ten centimeters per second in the algae cultivation pond; and

providing a head to the jet that overcomes a head loss associated with the velocity of fluid flow of at least ten centimeters per second in the algae cultivation pond.

17. The system of claim 14, wherein the method executed by the processor further comprises generating a report based on the measured pH.
