Investigation, biokinetic calculation, and modelling of a real combined industrial wastewater biological treatment process by activated sludge models
Background: Treatment of combined industrial wastewater from industrial parks is one of the most complex and difficult wastewater treatment processes. Also, the accuracy of biological models for the prediction of the performance of these processes has not been sufficiently evaluated. Therefore, in...

| description | Background: Treatment of combined industrial wastewater from industrial parks is one of the most
complex and difficult wastewater treatment processes. Also, the accuracy of biological models for the
prediction of the performance of these processes has not been sufficiently evaluated. Therefore, in this
study, the International Association on Water Quality (IAWQ(-Activated Sludge Model No. 1 (ASM1)
was implemented for the Jey industrial park in Isfahan province, Iran.
Methods: The Jey IPWWTP process is a combination of anaerobic and aerobic biological processes.
To evaluate the overall performance of IPWWTP, organic compounds, suspended solids, nutrients,
attached biomass, and some operating parameters were measured during 6 months. Then, the biokinetic
coefficients of aerobic processes were determined using Monod equations. Finally, the aerobic processes
were modeled using ASM1 implemented in STOAT software.
Results: The values of the biokinetic coefficients K, Y, Ks, Kd, and µmax were calculated as 2.7d-
, 0.34 mg
VSS/mg COD, 133.36 mg/L COD, 0.03d-
, and 0.93d-
, respectively. Based on the default coefficients and
conditions of the ASM model, the difference between the experiments and model prediction was about
2 to 98%. After calibrating the ASM model, the difference between the experiments and prediction in
all parameters was reduced to less than 10%.
Conclusion: Investigations showed that the default coefficients and operation conditions of the ASM1
model do not have good predictability for complex industrial wastewaters and the outputs show a
low accuracy compared to the experiments. After calibrating the kinetic coefficients and operating
conditions, the model performance is acceptable and the predictions show a good agreement with the
experiments. |
