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.
