Hello,

I post here the logging screen and the system error.

Thanks,
Kind regards.

Hello,

I want to calibrate my case study in Steady State conditions.

Thus, I would like to compare the last value from each simulation with my "observed value"?

Could you please help because I'm having problemas with the format of my observed values file.

In the steady state simulation, I set Stop at 50 days,

I wrote my observed value file like this:

#.t .out_1.COD .out_1.TSS
#d g/m3                 g/m3
50 76,635       39,947

but when I did Parameter estimation I got this error:

System error: Incorrect time in buffer file, line 4: 0, C:\.......

Could you help me please?
Kind regards,
Joao Vieira

Hello,

Regarding "BOD is the combination of S_S, X_S and part of X_BH, X_BA."

Is there some approximate value for part of X_BH contributing to bCOD? 

Thank you,
João

Hello Enrico,

Joining to the discussion ... when you mention BOD are you refering to "DO comsumption after 5 days" or b(iochemical)COD?

In WEST and using the standard fractionation, bCOD is approximately S_S + X_S + X_BH?

Thank you,
João

Thank you.

Hello,

Where could I find details about the objective function used by WEST in the Parameter Estimation Experiment?

Thank you,

Hello,
Could you please tell me the difference betwwen (two) flow splitter and (two) fraction splitter? Or where can I find the information?

Thank you,
Best regards,

Hello,
Please, where can I find a description about the settling/sedimentation modelling approach used in WEST?
Thank you,
Kind regards,

In the tracer test experiment, is there any relation between the volume of the 5 equalization tanks and the volume of the real activated sludge reactor?
Thank you

Hello,
I'm working with ASM1 to model a WWTP with a plug-flow biological reactor. Is there any reference for calibration and validation of ASM1 models, in particular:
- Monitoring data required;
- More important parameters to be calibrated.
Thank you
