“…The dynamic modelling of the process of activated sludge became an essential tool for the design and the management of WWTPs [ELSHORBAGY, SHA-WAQFAH 2015;INSEL et al 2012]. However, the calibration of these models seems to be a critical point in their wide-spread application [SIN, VANROLLEGHEM 2007].…”

Treatment performances of two wastewater treatment plants (WWTPs), located in North-Eastern Algeria (Souk-Ahras and Sedrata) were tested using ASM1 model.The model, to be considered as a decision tool for the appropriate management of activated sludge systems, served for the prediction of both WWTP behaviours under different operating conditions. In Sedrata WWTP the first management scenarios is based on an increase of inflow rate, taking into account a new transfer volume from a nearby zone. In a second scenerio, the ultimate flow of 40 000 m 3 ·d -1 is estimated. Regarding Souk-Ahras WWTP, three scenarios were tested. The first tested the impact of an increase of the extraction flow rate and yielded a reduction by 37% of sludge production. The second dealt with the management of the mass budget of substrata and biomass. Finally, the third application was devoted to the estimation of the plant ultimate capacity, estimated to be 60 000 m 3 ·d -1.

“…In a recent paper, Insel et al [1] rhetorically asked if the standard WWTP design methods are suitable for any municipal wastewater. Before the 1980, the answer to this question would probably have been positive: at that time, the goals required for wastewater treatment plant were the removal of solids and organic matter, so the plant design methods complied with these purposes.…”

“…As is known, in the last two decades, the standards for wastewater constituent removal have changed: the new regulations request strict effluent criteria from wastewater treatment plants into the water bodies. Therefore, appropriate process design and control issues are of great importance to maintain sustainable and cost-effective treatment under variable environmental conditions [1].…”

“…Dynamic models of activated sludge processes have demonstrated to be an indispensable tool in plant design and management [1][2][3][4]; however, their calibration appears to be the bottleneck in their widespread application [5]. According to Petersen et al [6], the calibration is the adaptation of the model to fit a certain set of information obtained from the full-scale WWTP under study.…”

The management of wastewater treatment plants to comply with new strict effluent criteria is a great concern: the activated sludge modeling, when supported by an accurate calibration process, could be an essential tool for this purpose. In the present paper, three WWTPs were characterized in order to support their up-grade. Influent characteristics and activated sludge performances were studied by application of respirometry. Plant operations were simulated by BioWin software (EnviroSim Associates Ltd., Canada). The goodness of the simulation, checked by the calculation of the average relative deviation between measured and simulated data, demonstrated that the model was able to predict the plant performances

BACKGROUND The study aimed to set forth a model simulation approach for an accurate calculation of denitrification potential (NDP) and selection of appropriate anoxic volume (VD) in biological nitrogen removal. Simulations utilized the characteristics of a typical sewage and the model coefficients associated with a model structure that included all relevant microbial processes. They were carried out first for a fully anoxic reactor sustained with excess nitrogen and then for a pre‐denitrification system operated with different anoxic volume ratios (VD/VT) of 0.1–0.4 when the influent nitrogen (TKN) level was set as 57 and 85 mg N L−1. RESULTS Without nitrate limitation, generated NDP could reach 37 mg N L−1 for VD/VT = 0.1 and gradually escalated to 56, 75 and 86 mg N L−1 when VD/VT was raised to 0.4. Results for the pre‐denitrification system showed the effect of nitrate limitation on both substrate removal and NDP levels: At VD/VT = 0.4, NDP associated with TKN = 85 mg N L−1 was approximately 60 mg N L−1, while it remained basically around 40 mg N L−1 with TKN = 57 mg N L−1. Simulation also indicated that the hydrolysis kinetics significantly affected NDP generation. CONCLUSION Simulation results revealed that stoichiometric estimations always underestimated NDP, recommending unnecessarily high anoxic volumes, where the oxidized nitrogen was consumed within the 20–25% portion of the provided volume. The remaining volume fraction was then totally wasted since it was forced to operate under anaerobic conditions, with practically no useful microbial activity and negligible substrate utilization. © 2019 Society of Chemical Industry
