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.

Systems and methods for algae cultivation using direct air capture

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.

Biological and algae harvesting and cultivation systems and methods

An algae cultivation system includes generating a translating hydraulic jump wave that travels across a gas-liquid interface of an algae cultivation fluid contained in the algae cultivation system. The translating hydraulic jump wave has Froude number greater than 1.

Sloped, shallow depth algae cultivation systems and methods

Algae harvesting and cultivating systems and methods for producing high concentrations of algae product with minimal energy. In an embodiment, an algae harvesting method is provided for performing dead-end filtration in an algae harvesting system having at least one treatment tank defining a plurality of filtration stages including at least a first filtration stage and a second filtration stage. An algae medium is pulled through the hollow fiber membranes such that a retentate and a permeate are produced.

Algae cultivation systems and methods with bore waves

An open raceway algae cultivation system includes a channel configured to contain an algae cultivation fluid. The channel includes a contraction zone having a width and a depth. A pump is configured to circulate the algae cultivation fluid in the channel. A width of the contraction zone decreases leading into the entrance of the pump and a depth of the contraction zone is greater than a depth of at least a portion of the channel located outside of the contraction zone.

Algae cultivation systems and methods with reduced energy loss

Algae cultivation systems and methods account for weather variations that can affect algae cultivation. In one system, an open raceway algae cultivation system includes a channel having a high section and a low liquid collection section. The channel is sloped to allow substantially all of an algae cultivation fluid in the high section to flow downwardly into the low liquid collection section. A barrier is removably positioned in the high section and a drain is positioned in the high section such that, when substantially all of the algae cultivation fluid has collected in the low liquid collection section, any rainwater that falls in the high section flows into the drain, without the rainwater mixing with the algae cultivation fluid in the low liquid collection section.

Algae cultivation systems and methods adapted for weather variations

A system and method for creating a useful carbon-enriched media in a reactor which will assimilate carbon into an algae biomass, requires measuring a respective carbon concentration of the media, C, as it enters, and as it leaves the reactor. Operationally, desired carbon concentration values are preset, C, and are provided along with values obtained for Cas input to a system controller. Respective differentials between Cand Cat the reactor's input and output ports are determined by the controller and are used to control a volumetric fluid flow rate of the media through the reactor. Specifically, the controller establishes a volumetric fluid flow rate of the media as it is passed through an absorber where the media is carbon-enriched by interaction with combustion gases from an external source (e.g. a power plant).

Controlled system for supporting algae growth with adsorbed carbon dioxide

A system and method for using a pulse flow to circulate algae in an algae cultivation apparatus are provided. In order to counteract the negative effects of biofouling on algae cultivation equipment, a pulse flow is created to periodically move through an algae cultivation apparatus. The pulse flow will dislodge algae cells adhering to various surfaces of the apparatus, and it will also create turbulence to stir up any algae cells which may have settled onto the bottom of the apparatus. To produce an increased fluid flow rate required to create an effective pulse flow, a sump, which is periodically filled with drawn algal culture from the apparatus, is located at an elevated position above the apparatus. When released, the algal culture travels through a transfer pipe and into the apparatus with gravity causing the algal culture to flow at a very high rate.
