The Feasibility of Pilot Production of Arthrospira maxima Cultivated in Semi-Closed Raceway Pond in Republic of Korea

Abstract

This study reports a novel microalgae raceway with 40 ton culture medium, which is modified from traditional paddlewheel-driven raceways. To control cold and heat in the raceway during winter season, the pond is excavated to 1 m-deep substrate with passive solar green house constructed by building information modeling (BIM). The flow and mixing rate (15-30 rpm) of seawater is controlled by new developed paddlewheel and controller. For optimizing the design factors of the mixing ground, flow visualization, velocity measurement and cell density ultrasonic detector were employed to investigate the flow mixing features. An optimized pilot plant design for microalgae mass cultrue ing temperate area and details of mixing are presented. The capability of the pilot production of Arthrospira maxima and other microalgae was tested in Ansan, South Korea (37 287 N, 126 833 E).ate with passive solar green house constructed by building information modeling (BIM).
