  • Biological and algae harvesting and cultivation systems and methods
    Patent number: 11952567
    Abstract: Algae harvesting and cultivating systems and methods for producing high concentrations of algae product with minimal energy. In an embodiment, a dead-end filtration system and method includes at least one tank and a plurality hollow fiber membranes positioned in the at least one tank. An algae medium is pulled through the hollow fiber membranes such that a retentate and a permeate are produced.

  • SYSTEMS AND METHODS FOR ALGAE CULTIVATION USING DIRECT AIR CAPTURE
    Publication number: 20210386029
    Abstract: Embodiments of the disclosure provide systems and methods for supplying an algae cultivation fluid with nutrients (e.g., carbon dioxide and nitrogen) directly from the atmosphere. Supplying nutrients directly from the atmosphere reduces operational costs and environmental impacts, as well as provides greater flexibility in locating algae farms.
