Hallo ASIM staff, i would really ask about the effect of changing the initial conditions in a reactor,should we chang it? or leave it? i mean, i have operated a pilot reactor, and measured the total COD in the aeration tank day by day, for example: CODtot in the aeration tank was 1800 mg/l, should i divide this value according to the division in the initial data in ASM, or i just leave the same data in ASM? i am waiting your answer Best regards Anas
Dear Anas: You have to differentiate between influent loading and initial conditions for a simulation. The influent loading and influent wastewater have a large influence on the model prediction. But the initial condition does not have a large effect. ASIM will first calculate a steady state anyways where the steady state is independent of the initial conditions. I hope this is helping with your question. Best regards, Eberhard.
