Three different aeration plates are used to study their effect on gas holdup and flow regime transition in fiber suspensions. The aeration plates differ by their open-area ratios (A=0.57%, 0.99%, and 2.14%), where the hole diameter remains the same while the number of holes increase. Experiments are performed using three different Rayon fiber lengths (L=3, 6, and 12mm) over a range of superfici...

Abstract Aeration is the process of increasing dissolved oxygen (DO) content water, which an important water quality parameter for survival aquatic life. In this process, large amounts air bubbles develop; as a result, contact surface area increases, and hence water-air-mass transfer accelerates. There are numerous methods DO concentration in including self-aeration, mechanical aeration, chemic...

This work investigated the role of an agnail device (manually made from a comb) on sludge size restriction and organic degradation in extended filamentous aerobic granular sludge-sequencing batch reactors (AGS-SBRs) with artificial wastewater. Two identical SBRs (R1 R2) were employed this experiment. Extended AGS large was achieved both by seeding dewatering day 40. R1 (the control) did not use...

Pilot plant study showed that there is a relationship between the HRT in aeration tank and the % removal of soluble COD in the final settler if DO is not a limiting function. It was found that the % removal of soluble COD in final settler increased from 13 at HRT in aeration tank of 12 hours to 45 at HRT of 4 hours. Mathematical model was also presented in order to predict the soluble COD utili...

Communication through the Pores of Kohn leading to partial aeration of the sequestration was responsible for the partial aeration seen after bronchoscopy. Srikanth, et al.(2) reviewed 57 cases and reported that bilateral com...
