Biofiltration is gradually gaining popularity among biological wastewater treatment processes, becoming a valid alternative to the more widespread activated sludge system. In order to understand better the operating conditions that influence the efficiency of such a process, a mathematical model has been developed. It allows the calculation of the COD and N-NH4 profiles along the filter height and inside the biofilm and simulates filter clogging due to the biomass growth. The model output has been verified through a series of sensitivity tests and its results have been calibrated considering the results of an experimental campaign conducted on the Biostyr biofiltration unit of the Rome southern municipal wastewater treatment plant. Such a model can be used to understand better the influence of variation of the operating conditions on the efficiency of the biofiltration process, furthermore representing a valid predictive tool for the management of existing wastewater treatment plants and for the design of new ones.

Abstract
Biofiltration is gradually gaining popularity among biological wastewater treatment processes, becoming a valid alternative to the more widespread activated sludge system. In order to understand better the operating conditions that influence the efficiency of such a process, a mathematical model has been developed. It allows the calculation of the COD and N-NH4 profiles along the filter height and inside the biofilm and simulates filter clogging due to the biomass growth. The model output has been verified through a series of sensitivity tests and its results have been calibrated considering the results of an experimental campaign conducted on the Biostyr biofiltration unit of the Rome southern municipal wastewater treatment plant. Such a model can be used to understand better the influence of variation of the operating conditions on the efficiency of the biofiltration process, furthermore representing a valid predictive tool for the management of existing wastewater treatment plants and for the design of new ones.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
