Abstract : There is little doubt that the factors discussed above --excess biological solids accumulation, channeling, biological solids transport, suspended versus attached solids and media size, shape, porosity and pore size--all affect performance to some extent, and the interrelationship between these factors is expected to be quite complex. However, Young (2) and Dahab (7) succeeded in establishing reasonable agreement between measured COD removal performance and the performance simulated by use of a computerized model that integrated the effects of these factors with biological growth and substrate utilization kinetics. These modeling efforts, combined with measurements from laboratory-scale factors operating over a broad range of operating conditions, helped to establish a basis for developing criteria for selecting media and for sizing full-scale anaerobic filters.
