  • Systems and methods for processing algae cultivation fluid
    Patent number: 8926844
    Abstract: Systems and methods for reducing an amount of unwanted living organisms within an algae cultivation fluid are provided herein. According to some embodiments, methods may include subjecting the algae cultivation fluid to an amount of cavitation, the amount of cavitation being defined by a pressure differential between a downstream pressure and a vapor pressure, the pressure differential divided by half of a product of a fluid density multiplied by a square of a velocity of an apparatus throat.
    Type: Grant

  • Unitary stratified composite
    Patent number: 7465373
    Abstract: An unitary stratified composite composed of a first stratum and a second stratum integrally connected by a transition zone is disclosed. The first stratum serves as a liquid acquisition stratum that rapidly acquires and then transfers liquid to the second stratum. The second stratum serves to withdraw liquid from the first stratum and further severs as a temporary storage stratum. Methods for forming the unitary stratified composite are also disclosed.
