  • Publication number: 20150087049
    Abstract: The invention relates to a research photobioreactor for growth at extremely high cell densities in axenic cultures of cyanobacteria and microalgae exposed to a high light intensity. A hydrophobic gas-permeable first membrane situated at the bottom of the reaction chamber serves for the entry of CO2 into the cell suspension. The first membrane separates the CO2 containing gaseous phase in a basis chamber from the cell suspension that covers the membrane. It has a permeability coefficient for the gases of air many times that of the physically feasible rate of absorption of these gases in water. The turbulent flow within the cell suspension is obtained by shaking. A high shearing rate hereby realized increases the CO2 absorption rate in the liquid phase close to the membrane, thus avoiding C-limitation. A porous hydrophobic gas-permeable second membrane separates the reaction chamber from at least one gas exchange chamber.

  • Publication number: 20150056685
    Abstract: The invention relates to a method and to a device for feeding gases or gas mixtures into a liquid, suspension, or emulsion in a reactor in a specific manner. According to the invention, gases or gas mixtures are fed into a liquid, suspension, or emulsion in a reactor in a specific manner, wherein the gas or gas mixture is fed in a specific amount and/or at defined points in time in one pulse as a gas bubble into a flowing liquid in a tilted reactor system, whereby a pulsation effect is obtained, wherein a driving force is produced by means of an adiabatic relaxation of the fed-in gas or gas mixture, by means of which driving force wall adhesions on the reactor are prevented.

  • Patent number: 8945916
    Abstract: A device and system for growing of a photosynthetic culture is provided which employs one or a plurality of vertically disposed photopanels having interior cavities configured for holding liquid and the photosynthetic culture such as algae. Interior surfaces are enhanced in size by projections defined by deformation in sidewalls of the photopanels. The projections communicate between the sidewalls also providing structural integrity to the photopanel and allowing for thinner sidewalls and increased light transmission therethrough. The system may employ a support rack and pivotal mount to each such photopanel to allow positioning adjacent to each other in rows. Pivoting during different lighting conditions afforded the racked photopanels provides a manner to reduce light blockage to individual photo panels from adjacent photopanels.

  • Patent number: 8940531
    Abstract: A system for culturing and recovering micro algae comprises a photo-bioreactor, a floatation separator, a centrifugal separator, and a micro bubble generator. The photo-bioreactor unit is configured to culture micro algae by a photochemical reaction to produce a micro algae precipitate. The precipitated micro algae is separated by the floatation separator. The separated micro algae is concentrated by the centrifugal separator. The micro bubble generator generates process water containing micro carbon dioxide bubbles and supplies the generated process water to the photo-bioreactor unit and the floatation separator. With this system, micro algae can be cultured and recovered in a simpler and more cost-effective manner.

  • Publication number: 20150004685
    Abstract: This process is unique in that it provides a continuous photosynthetic bioreactor for carbon sequestration. An on-site bioreactor directly decreases the concentration of carbon dioxide in the emissions of fossil fuel consuming units. In this process, an algal medium is maintained in a bioreactor. Light is provided through artificial means. Nutrients are added in a cross flow pattern and waste products are removed as they are created, allowing for maximum growth of the algae.
