Hydrodynamics of hybrid upflow anaerobic sludge blanket reactors using tracer studies

The hybrid upflow anaerobic sludge blanket reactor (HUASB) is a modified UASB wherein, inert media variants are used to prevent the biomass washout and its circular shape reduces biological and hydraulic dead zone. The flow pattern is crucial to facilitate hydraulic behavior as it has a direct effec...
