Likewise, a horizontal settling basin operating at 1.1 gpm/sf performs nearly as well as the same basin operating at 1.0 gpm/sf.

Dans certains bioréacteurs la circulation du fluide en fermentation n’ est pas organisée à l'intérieur d’une même enceinte, dans deux compartiments concentriques, mais dans deux colonnes séparées. C'est le cas du fermenteur à boucle externe mis au point par I. C. I. pour produire de la biomasse bactérienne à partir de méthanol [...] Ce bioréacteur a une hauteur de l'ordre de 30 m. Dans la colonne montante, a lieu la principale phase d’oxygénation. L'air est introduit par un tuyau perforé(sparger). À la partie supérieure, elle communique avec une canalisation horizontale munie d’une ouverture permettant la sortie du gaz effluent. A l'entrée du compartiment descendant une réinjection d’air est faite. Elle provoque une augmentation de la vitesse de circulation vers le bas, dans la partie où est placé l'échangeur de chaleur de façon à obtenir un bon coefficient d’échange thermique. 1, record 6, French, - fermenteur%20%C3%A0%20boucle%20externe

The introduction of DEAE or CM groups into crosslinked agarose or acrylic copolymers gives ion exchange Sepharoses (Pharmacia) and Trisacryl (LKB). These two types of exchangers have a high capacity for proteins, and small, uniform bead shaped articles which support high flow rates.
