Abstract

Des méthodes (100, 200) permettant d'augmenter la durée de conservation d'une biomasse de micro-algues sont fournies. Ces méthodes peuvent inclure les étapes suivantes. Extraire une biomasse de micro-algues en utilisant un premier filtre ; ici, la teneur en eau de la biomasse des microalgues est supérieure à 80%. Ensuite, on rince une partie de la biomasse de microalgues dans une solution pour éliminer sensiblement au moins une substance indésirable de la biomasse de microalgues. Ensuite, en filtrant une seconde fois la biomasse de micro-algues à l'aide d'un second filtre pour éliminer le fluide en excès, le second filtrage diminue ici la teneur en eau de la biomasse des micro-algues. Ensuite, en séchant la biomasse de micro-algues à l'aide d'un dispositif d'élimination de l'eau, le seuil de teneur en eau de la biomasse des microalgues est réduit à un premier seuil Certains modes de réalisation peuvent en outre comprendre la détermination du fait que la micro-algue est issue d'eau salée ou d'eau douce et, par conséquent, la sélection d'une solution de rinçage appropriée. D'autres modes de réalisation peuvent inclure des étapes de séchage supplémentaires.
