Effects of biomass entrapment and carrier properties on the performance of an air-fluidized-bed biofilm reactor
In air-fluidized-bed bioreactors (AFBBR) for wastewater treatment, reactions were found to take place mainly in the biofilm formed on the surface of the carriers, even when a large number of microorganisms were immobilized in the carriers by an entrapping method. A cylindrically shaped, expanded polypropylene carrier (CEPPC) that is capable of holding a large quantity of microorganisms was developed and tested in continuous experiments. The AFBBR process was proven to be applicable to a high biological oxygen demand (BOD) loading treatment, and the ammonia nitrogen removal rate of the AFBBR process was determined to be higher than that of the fill-and-draw type activated sludge process.
