Techniques à membranes appliquées à l'élimination des matières en suspension dans un circuit semi-fermé d'aquaculture

Abstract: Les piscicultures en circuits semi-fermés sont confrontées au problème de l'élimination permanente des matières en suspension (M.E.S.) et des substances azotées. Les procédés conventionnels utilisés pour retenir les M.E.S. (décantation, hydrocyclones, filtres mécaniques à tambour rotatif, filtration gravitaire) ne donnent par entière satisfaction. Par contre, la filtration sur membranes permet d'arrêter en totalité les particules en suspension et les bactéries. On montre d'abord que les teneurs en M.… Show more

“…Also, lowpressure membrane processes, such as UF (dead-end), are effective for treating algae-laden waters [19]. In addition, hollow fiber membranes are especially widely used in MBR for wastewater treatment [20,21] but, for some years, have been used in marine aquaculture field or for seawater pre-treatments [4,[22][23][24][25][26][27][28][29][30][31][32][33].…”
