Activated Granular Aerobic Sludge Biofilm Reactors Aerobic Reactor
Aerobic Reactor Introduction:
In an aerobic reactor, the product conversion rate or the degradation rate is mainly based on the bubble size and gas-to-liquid mass transfer rate. Oxygen solubility is a main parameter that should be optimally maintained because the presence of salt may hinder the solubilizing property of oxygen. Simple aerobic bioreactors can be constructed with aerated lagoons or oxidation ponds for the storage of the waste in the open environment and with a rotating disk that contains the microbe as a biofilm for regular churning.
Examples of commonly used aerobic bioreactors at an industrial scale include stirred tank bioreactors, airlift bioreactors, and inverse fluidized bed bioreactors. The most common aerobic reactor is the stirred tank reactor where air is sparged from the bottom of the reactor. In the airlift bioreactor mixing is provided by the turbulence created by gas. The oxygen transfer coefficient is high for airlift reactors compared to that of stirred tank reactors.
