Última Procédés de traitement de l'eau de mer en conchyliculture pour la sauvegarde et le maintien de la qualité des mollusques bivalves ArchiMer Castaing, Jean-baptiste. The aim of this work is the study of seawater filtration process to preserve commercial bivalves and main tain their quality during harmful algal blooms. The originality of this work is based on the study of rustic processes, capable of removing toxic microalgae from seawater. Two filtration processes have been studied, the immersed hollow fibres membranes and a sand filter. The origin and nature of fouling mechanisms have been identified in connection with the selectivity and energy consumption . Suspensions of toxic and nontoxic microalgae were reconstituted and then filtered through 10 kDa, 300 kDa and 0.2 µm membranes and a sand filter (mean grain diameter dg equal to 250-520 µm). Microfiltration membrane 0.2 µm has emerged as the most suitable for the...

Rapport final ArchiMer Haure, Joel; Hussenot, Jerome; Buzin, Florence; Dupuy, Beatrice; Palvadeau, Hubert; Penisson, Christian; Papin, Mathias; Nourry, Max; Lassus, Patrick; Marcaillou-le Baut, Claire; Mondeguer, Florence; Royer, F.; Amzil, Zouher; Belin, Catherine; Cardinal, Mireille; Le Grel, L.; Le Bihan, V.; Jaouen, P.; Massé, A.; Castaing, Jean-baptiste; Sabiri, Ne.; Pontié, M.. La contamination des denrées d’origine marine par des toxines algales (phycotoxines) a pris depuis quelques années une importance considérable. Ce phénomène est largement lié à l’augmentation du nombre de zones géographiques touchées ainsi qu’à la diversification des espèces toxinogènes et à l’identification de nouveaux composés toxiques. Les données épidémiologiques sont cependant encore peu nombreuses car elles sont liées à la mise en place de contrôles systématiques récents. L’Union Européenne a établi un Laboratoire Communautaire de référence pour les phycotoxines, situé à Vigo (Espagne) qui coordonne les activités des laboratoires Nationaux de références correspondants (en France c’est le LNR Phycotoxines de l’AFSSA qui assure cette mission). C’est...

In this study, an original use of immersed microfiltration membranes (mean pore size equal to 0.2 mu m) is investigated for the total removal of toxic dinoflagellates from seawater. Using a membrane autopsy and fouling model approach and the use of fouling indexes (called Pore Blocking Index, Pore Constriction Index and Cake Filtration Index), three dinoflagellate suspensions (Heterocapsa triquetra, Alexandrium minutum and Prorocentrum lima) have been microfiltered in order to study the influence of micro-algal species and its concentrations (1,000 and 30,000 cells/mL) on filtration yield and membrane fouling mechanisms. Results showed that all micro-algae have been retained after 180 min of microfiltration. At 30,000 cells/mL, permeate fluxes declined...
