WebA critical design parameter related to reactor shape is the height-to-diameter ratio H/D, or H:D. Tall, thin reactors with H:D > 3:1 enable long liquid residence times of gas bubbles sparged from the bottom, allowing an effective gas-to-liquid mass transfer. However, in tall and thin reactor designs, the headspace surface area is limited, and ... WebSemi-batch biological reactors have been de fined elsewhere as fill-and-draw or sequencing batch reactors. Their operation has been de scribed fully by Irvine et al.1 One cycle for one reactor would consist of fill, react, settle, draw, and idle periods. Prior to a fill period, settled solids would be contained in the bot tom portion of the ...
