Abstract
The design Of a three-phase fluidized bed bioreactor using novel biomass support for industrial wastewater treatment is reported in this paper. A column of 0.20 m diameter with variable height up to 6.60 m equipped with a foam breaker tank was designed, commissioned and operated. A novel biomass support, KMTR support, has been used Separate gas and liquid feeding systems were designed to facilitate proper bioreactor operation. A flat distriburor plate with 4 mm holes- diameter was desined A study on the hydrodynamic properties of the three-phase fluidized bed bioreactor revealed high values of bed expansion and air hold-ups. Purification efficiencies Of and are reported for brewery and refinery wastewater samples, respectively. The values of the volumetric oxygen transfer coeficients reached up to 120 h", depending on the biorector model used. All available informationhave been used in the design work, details are given for each component and design Step. A compromise has been reached between many design aspects. It has been concluded that the support should be used in industrial wastewater treatment, and that bioaugmentation techniques can improve the oxygenation and wastewater purification eficiencies of the bioreactor.
