Performance studies of aerobic FBBR for the treatment of dairy wastewater

As the dairy wastewater produces lot of pollution problems, treatment of wastes before disposal becomes important. The endeavor to have a continuously operating, non clogging biofilm reactor with no need for backwashing, and high specific biofilm surface area culminated in the most advanced technology of Aerobic Fluidized Bed treatment where the biomass grows on small elements that move along with the water in the reactor. By the study, the FBB has been proved as highly efficient for strong dairy wastewater treatment. For an organic loading in the range 2.2 to 10.2 kg COD/m3d the efficiency variation was from 94.58 to 82.11%. The reactor combines all the advantages and best features of conventional treatment systems while eliminating the drawbacks of those.
