Reactor diameter to height ratio
WebPneumatically agitated bioreactors are of two type’s viz., the bubble column and air-lift (Fig. 28.4). These bioreactors are tall and thin as compare to mechanical agitation type reactors. Typically, the height-to-diameter ratio in pneumatically agitated bioreactors is high. WebFor the microbial reactor, there are two major factors that affect H:D ratio. Microbial runs are typically 24 hours or less as the growth rate is so high. With a high growth rate, the sparge …
