Modeling and simulation of the sequencing batch reactor at a full‐scale municipal wastewater treatment plant

Abstract

in Wiley InterScience (www.interscience.wiley.com).In this work, we attempted to modify the Activated Sludge Model No.3 and to simulate the performance of a full-scale sequencing batch reactor (SBR) plant for municipal wastewater treatment. The long-term dynamic data from the continuous operation of this SBR plant were simulated. The influent wastewater composition was characterized using batch measurements. After incorporating all the relevant processes, the sensitivity of the stoichiometric and kinetic coefficients for the model was thoroughly analyzed prior to the model calibration. The modified model was calibrated and validated with the data from both batch-and full-scale experiments. Model predictions were compared with routine data in terms of chemical oxygen demand, NH 4 þ -N and mixed liquid volatile suspended solids in the SBR, combined with batch experimental data under different conditions. The model predictions match the experimental results well, demonstrating that the model is appropriate to simulate the performance of a full-scale wastewater treatment plant even operated under perturbation conditions.

Aerobic sludge granulation in a Reverse Flow Baffled Reactor (RFBR) operated in continuous-flow mode for wastewater treatment

“…For comparison, the aerobic granulation produced by a lab-scale SBR [11], a pilot-scale SBR [12] and a full-scale SBR fed with municipal wastewater [13] were reported. Periodic feast-famine condition, short settling time (selection pressure) and height/diameter (H/D) ratio in SBR have significant effects on aerobic granular sludge formation [5,6,14].…”

Calibration and validation of an activated sludge model for a pilot-scale anoxic/anaerobic/aerobic/post-anoxic process

“…Facing diverse organisms and complicated conversion processes in a BNR system, activated sludge mathematical models have proved powerful and valuable tools (Petersen et al, 2002;. In recent years, many mathematical models based on the activated sludge model (ASM) family (ASM1, ASM2, ASM2d, and ASM3) have been evaluated and optimized for BNR processes such as anaerobic/anoxic/aerobic (AAO) (Pai, 2007;Liwarska-Bizukojc et al, 2011), Johannesburg (JHB) (Makinia et al, 2006), modified University of Cape Town (MUCT) (Czerwionka et al, 2012), sequencing batch reactor (SBR) (Ni et al, 2009), and membrane bioreactor (MBR) (Fenu et al, 2010). A novel anoxic/ anaerobic/aerobic (modified AAO) process with an anoxic stage before an anaerobic stage, developed by Zhang and Gao (2000), has shown high removal efficiencies for nitrogen and phosphorus from low C/N wastewater.…”

Microbiological and Performance Evaluation of Sequencing Batch Reactor for Textile Wastewater Treatment

“…A sequencing batch reactor (SBR) system is an alternative to conventional systems for treatment of industrial and domestic wastewater. The SBR systems are convenient for organic matter and nutrient removal (Droste, 1997;Teichgraber et al, 2001;Ileri and Damar, 2005;Ni et al, 2009). A SBR indicated relatively high performance over conventional suspended growth systems (Cheong and Hansen, 2008;Kim et al, 2008).…”
