Abstract: A method includes containing an algae slurry within a cultivation vessel, introducing the algae slurry into a dissolved air floatation (DAF) system, and operating the DAF system in a low-recovery mode and thereby selectively removing impurities from the algae slurry. Algal biomass is then harvested from the algae slurry after removing the impurities from the algae slurry.

Abstract: A system includes an algae bioreactor that contains an algae slurry, a heat exchanger in fluid communication with the algae bioreactor to receive the algae slurry from the algae bioreactor and heat and increase a pressure of the algae slurry, and one or more valves and a flash vessel in fluid communication with a discharge of the heat exchanger to flash the algae slurry and create steam and algae biomass. A separator receives the algae biomass from the flash vessel and separates oils from the algae biomass to generate a biofuel.

Abstract: Scale-up evaluation methods for algal biomass cultivation are provided, and more particularly, simultaneous scale-up evaluation methods for outdoor algal biomass cultivation are provided. The methods control various process variables to isolate the impact of scaling algal biomass cultivation, thereby permitting enhanced scale-up operation design to optimize the quality and quantity of algal biomass.

Abstract: The present disclosure relates to algae cultivation including the integration of liners for large-scale open algal biomass to facilitate algae facility commercial scale-up operations. Liners include those having a first portion having a first thickness and a second portion comprising a second thickness, wherein the first thickness and the second thickness are different. Liners also include those having a first portion having a first thickness, a second portion comprising a second thickness, and a third portion comprising a third thickness, wherein the first thickness, the second thickness, and the third thickness are different.
