The Design of Airlift Fermenters for use in Biotechnology

The Design of Airlift Fermenters for use in Biotechnology

The airlift fermenter has an oxygen transfer rate of 60-90 mmol h-1 (see the equation p. 387). Because the fermenter is deep and the oxygen demand of the wastewater streams is generally quite low, the power requirement for such a unit can be minimized by locating the air spargers not at the bottom of

Culture of microalgae in hatcheries - Wikipedia

Microalgae is an important source of nutrition and is used widely in the aquaculture of other organisms, either directly or as an added source of basic nutrients. Aquaculture farms rearing larvae of molluscs, echinoderms, crustaceans and fish use microalgae as a source of nutrition. Low bacteria and high microalgal biomass is a crucial food source for shellfish aquaculture.

Mechanically agitated fermenters

Mechanically agitated fermenters

The cost for a mechanically agitated fermenter is defined as 1 for a 1500 m3 tank. The cost of a 1500 m3 air-lift fermenter is a bit lower than that of the equivalent mechanically agitated fermenter. However, the investment cost follows the 0.6 rule until 6000 m3 is reached. Above 6000 m3, more than one air lift fermenter may need to be used.
