Studies on the expansion characteristics of the granular bed present in EGSB bioreactors

YH Liu, YL He, SC Yang, CJ An


In this study, the expansion characteristics of an anaerobic granular bed in EGSB reactors based on terminal settling velocity study of the granules and the Richardson-Zaki equation (1954) have been investigated. The settling velocity study shows that the mean settling velocity of the granules is in accordance with the Allen formula because the settling process falls within the intermediate flow regime range (1
