Última A New Photobioreactor for Continuous Microalgal Production in Hatcheries Based on External-Loop Airlift and Swirling Flow ArchiMer Loubiere, K; Olivo, Erell; Bougaran, Gael; Pruvost, J; Robert, Rene; Legrand, J. This study deals with the scale of a new photobioreactor for continuous microalgal production in hatcheries. The combination of the state-of-art with the constraints inherent to hatcheries has turned the design into a closed, artificially illuminated and external-loop airlift configuration based on a succession of elementary modules, each one being composed of two transparent vertical interconnected columns. The liquid circulation is ensured pneumatically (air injections) with respect to a swirling motion (tangential inlets). A single module of the whole photobioreactor was built-up to scale its geometry (diameter and length) and to optimize its design (air sparger, tangential inlets). The volumetric productivities were predicted by modeling radiative... Tipo: Text Palavras-chave: Isochrysis affinis galbana; Swirling flow; Airlift; Hatchery; Continuous photobioreactor. Ano: 2009 URL: http://archimer.ifremer.fr/doc/2009/publication-5288.pdf Conception et étude d'un photobioréacteur pour la production en continu de microalgues en écloseries aquacoles ArchiMer Olivo, Erell. This thesis describes the conception and the study of a photobioreactor dedicated to aquaculture. The state of the art and the technico-economic constraints proper to this activity led to the choices to a simple reactor, volume variable, cheap to produce and reliable for continuous cultures. The elementary module is made of two vertical columns, connected by flanges. An airlift injection located at the base of the column (airlift reactor) generates a swirling flow circulation in order to minimize the biofilm development on the inner side of the column. A pilot of 6.1 liters has been conceived to study the radiative transfers, the hydrodynamics and the biological cultures in continuous mode. Coupling a radiative transfer model (two flux model) with the...

Les travaux présentés dans le cadre de ce rapport d'activité rendent compte des avancées réalisées sur le plan (1) biologique, avec d'une part une étude sur le comportement du genre Chaetoceros en culture continue et, d'autre part, les résultats d'expérimentations sur les performances d'élevages larvaires réalisés sur la base de cultures de microalgues en continu, et (2) technologique, avec la continuité des actions de développement du photobioréacteur destiné aux écloseries commerciales ainsi que des périphériques indispensables à son intégration dans le secteur aquacole.

Optimal culture conditions were investigated for the continuous culture of Isochrysis affinis galbana (T-Iso) by assessing the effects of irradiance, temperature, pH and nitrogen and phosphorus requirements. Assessment of the growth rate-irradiance relationship in a turbidostat experiment highlighted that an optimum irradiance efficiency for growth (E-mu) occurred at irradiance much lower than the saturating level. Furthermore, our modeling approach for productivity pointed out that an optimal set of irradiance and dilution rate could be achieved in order to maximize irradiance efficiency. Optimal conditions for growth were assessed for temperature, pH and irradiance by means of a factorial design experiment. The resulting model predicted that optimal...
