Assessment of dynamic models for a high rate anaerobic treatment process

Abstract A pilot scale HYBRID reactor was operated under steady state and dynamic conditions using a pulp and paper mill effluent as a feedstock. Data collected during experimentation on the pilot plant were used to evaluate two different mechanistic dynamic models of the process. Results showed that both models were adequate in qualitatively describing steady state and dynamic process behaviour but would be of limited use in directly providing estimates of process variables for control purposes.
