Experimental and Mathematical Investigation of Anaerobic Granulate Density via Settling Velocity

The objective of this study was to determine the density anaerobic granules on different heights a full-scale Upflow Anaerobic Sludge Bed reactor. defined through settling velocities granules, measured in In study, granular calculated with and developed mathematical model. model is based Stokes experiment, were taken from an reactor, 0.6 7.6 m. granules’ diameters varied between 1 5 mm. six velocity active (with gas granule pore surface granule) first. After measurement, placed vortex obtain degassed (granules without any pores or surface), for which also later. It shown that densities at are independent reactor height.
