The anaerobic biological fluidized bed process has been shown to be an extremely efficient system for the treatment of moderate and high strength industrial wastes. This is due to the extremely high specific surface and mass transfer properties of the fluidized bed system. Reported in this article are the results of over three years of pilot work on generating methane gas from whey using a Hy-FloTM anaerobic fluidized bed. The effect of organic loading rate, influent substrate concentration and temperature has been examined. Energy balances show the process to be a net energy producer, generating between 30.5 and 78.7 times the amount of energy required to operate the system.
