AEROBIC DIGESTER W11

Practical Training Exercises

• Acclimation of a completely mixed biological reactor
• Measurement of COD and MLSS changes as criteria of performance
• Establishing the stoichiometry and kinetics of aerobic biological processes
• Gas/liquid mass transfer
• Residence time distributions
• 100% scale-up to industrial requirements
• Studying the effect on effluent quality of: inflow substrate concentration ('loading rate'); liquid flow rate and reactor volume ('detention time'); air flow rate; temperature; pH stability; nutrient deficiency
