Evaluation of Nitrification Inhibition Using Sequencing Batch Reactors and BioWin Modeling, and the Effect of Aqueous Film Forming Foam on Biological Nutrient Removal
… A, B, and D (control) was performed with BioWin 3.1 (EnviroSim, Ltd.) as a means for comparison and to ensure reactors were performing as intended. Results suggest that there was some level of continuous inhibition for both NP RWI and PCI reactors, however no sporadic inhibition events …

Optimization of Biological Nitrogen Removal From Fermented Dairy Manure Using Low Levels of Dissolved Oxygen
… using default nitrifying kinetic parameters in BioWin®, a biological modeling simulator, which indicated the presence of a nitrification inhibitor in fermented dairy manure. Furthermore, an N balance during the aerobic zone indicated that simultaneous nitrification-denitrification (SND) was …

A Comparison of Wastewater Process Modelling Tools: Case Study of Potsdam WWTW
… Design (PWSSD) developed by Wu (2014); iii) BioWin 5.0 (developed by Envirosim Associates Ltd; Barker and Dold, 1997; Envirosim 2007); and iv) UCTPHO dynamic model (Wentzel et al., 1992). The goal was to compare the output and results of the various models adopted for this research under …

Development of High Efficiency Partial Nitrification as a First Step of Nitrite Shunt Process using Ammonium-Oxidizing Bacteria (AOB)
… has been developed and calibrated using BioWin software for long-term dynamic behavior of the lab-scale SBR at different nitrogen loading rates (NLR).

Evaluation of cost effective approaches for nutrient removal in urban stormwater and wastewater: City of Fort Collins case study
… nutrient removal technologies were modeled in BioWin® to be integrated with the existing modified Bardenpho unit. Approximately 1,500 stormwater control measures (SCMs) are implemented in Fort Collins at present; however, not all provide water quality treatment. Two alternative stormwater …

Enhanced Biological Phosphorus Removal from Dairy Manure to Meet Nitrogen:Phosphorus Crop Nutrient Requirements
… acids, respectively. The EBPR component of the BioWin wastewater treatment model was evaluated through a sensitivity analysis. The parameters to which effluent phosphate (PO4) concentration was most sensitive were maximum specific growth rate, growth yield, aerobic PO4 uptake rate per unit …

Effects Of Reduced Ras And Volume On Anaerobic Zone Performance For A Septic Wastewater Biological Phosphorous Removal System
… anaerobic P release. Computer modeling with BioWin and UCTPHO was found to predict similar results to the pilot test results. Modeling was done with reduced RAS flows to the anaerobic zone (100%, 50%, and 25% RAS), increased anaerobic volume, and increased hydraulic loading. The most …

Seasonal influent characterization, model calibration, SRT and energy usage for nitrogen removal at a full scale wastewater plant
… and primary effluent of the plant to calibrate a BioWinTM (version 3.1, EnviroSim Associates Ltd.) model. It was determined that denitrification during the warm season (May and July) were mostly similar to each other and different from the sampling periods data during the cold season (October and …

Evaluation of Alternative Electron Donors for Denitifying Moving Bed Biofilm Reactors (MBBRs)
… the bench-scale MBBR performance using BioWin 3.0, verified that μ<sub>max</sub> and boundary layer thickness play key roles in determining rates of substrate utilization. Adjustments in these parameters made it possible to mimic the MBBRs, but it is difficult to determine whether the …

Measurement of active biomass in activated sludge mixed liquor
… biomass concentrations as parameters (e.g. Biowin, Simba, GPX, UCTOLD, UCTPHO), the active mass parameters and the use of specific rates in terms of them, have become much more widely accepted. However, XH exists only hypothetically within the structure of the design procedures and kinetic …

Evaluation of Nitrification Inhibition Using Bench-Scale Rate Measurements, Profile Sampling, and Process Simulation Modeling
… sampling and plant data was performed with Biowin 3.1 (EnviroSim, Ltd.) as a means for comparison and to generate μmax values for AOB to compare with the original design μmax of 0.57-1. Profile sampling was conducted from the primary effluent to the secondary effluent with samples collected …
