The inverse gas-liquid-solid fluidized bed consists of a bed of particles with a lower density than that of the liquid which is fluidized by a downward liquid flow, opposite to the net buoyancy force on the particles, while gas is bubbled through the bed countercurrently to the liquid. This type of fluidized bed has been successfully applied on an industrial scale in the field of aerobic wastewater treatment, but very little information is available in the literature concerning the fundamental hydrodynamic behavior of the inverse gas-liquid-solid fluidized bed. This work examines the solids behavior in the inverse gas-liquid-solid fluidized bed, including the minimum fluidization velocity, the minimum gas velocity for particle suspension, and bed expansion.
