Notes:
The rate of oxygen absorption by aqueous sodium sulphite solutions in tower-type fermentors up to 6 in. in diameter was related both to tower diameter and to the number of sintered Pyrex disks used for dispersing air entering the towers. Maximal rates of absorption were obtained in towers 2.5 in. in diameter. Under comparable conditions, rates of oxygen transfer in towers containing one aeration disk were approximately 30% higher than those in similar towers containing two or more disks. In towers greater than 6 in. in diameter, the absorption rate was independent of vessel diameter and number of aeration disks when more than one disk was used. Bubble coalescence was the main cause of the difference in the rate of oxygen absorption.
