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.

According to present disclosure, there is disclosed an algae growth and cultivation system that provides a cost-efficient means of producing algae biomass as feedstock for algae-based products, such as, fertilizer, feed, biofuel manufacture, and desirably impacts, nutrient recovery from waste streams for valued byproducts production, recycle water, and alternative/renewable energy production. The system as discussed herein is an integrated systems approach to wastewater treatment, algal strains selection for byproducts production, and recycle of algal biomass-processing waste or additional algae harvested as feedstock for products such as fertilizer production. Embodiments of a system as discussed herein present an economically viable algae production system and process that allows algae-derived products such as fertilizer, feed, biofuels, etc. to compete with non-organic or petroleum products in the marketplace.

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 and an expansion zone having a width and a depth. A pump is configured to circulate the algae cultivation fluid in the channel and includes an entrance and an exit. 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. A bottom of the channel at a beginning of the contraction zone is lower than a bottom of the channel at an outlet of the expansion zone, and the contraction zone increases in depth along at least a portion of its length.

A method and system for flue gas reclamation is described. In one embodiment, a flue gas reclamation system is provided. The system includes a combustion engine including an intake member, an output shaft, and an exhaust outlet. The intake member receives flue gas from a gas source. A generator is connected to the output shaft and a compressor is connected to the exhaust outlet of the combustion engine. At least one holding tank is connected to the compressor and the compressor stores enriched flue gas from the exhaust outlet of the combustion engine in the at least one holding tank. A battery is connected to the generator and is configured to provide electric power to the flue gas reclamation system. An algae farm in fluid communication with the at least one holding tank is configured to receive the stored enriched flue gas from the at least one holding tank.

An algae cultivation medium includes a growth medium and at least one of an amine additive and a water-soluble biomimetic catalyst. A related method of increasing carbon shuttling in an algae cultivation medium includes adding at least one of the amine additive and the water-soluble biomimetic catalyst to the algae cultivation medium.
