GPS-X / ASM2d Wastewater Process Modeler (Activated Sludge Model Modification) Job Description I am looking for an experienced wastewater process modeler who is familiar with GPS-X and Activated Sludge Models (ASM2d). I currently have a GPS-X 7.0 ASM2d model. The model has already been extended based on an existing setup and can run normally, but the simulation results are not correct. This task is to directly check and modify the model itself, identify what is wrong in the current model, correct it, and make the results meet the required behavior. What I will provide - Current GPS-X 7.0 runnable model files - A document describing the requirements and current problems What you need to do - Review the existing ASM2d model implementation in GPS-X - Identify where the model is incorrect - Modify and correct the model - Deliver the complete corrected GPS-X model source files - Provide a short and clear summary explaining: - what was wrong in the original model - what you changed and fixed Important - This is not just parameter tuning - The model already runs; the task is to fix the model behavior and implementation Required experience / keywords Wastewater Process Modeler (ASM / ASM2d, GPS-X) Wastewater Process Modeling Engineer Activated Sludge Modeler Environmental Process Modeler WWTP Process Simulation Engineer - GPS-X wastewater modeling - Activated Sludge Model (ASM / ASM2 / ASM2d) - Wastewater Treatment Plant (WWTP) modeling - Biological nutrient removal (BNR) - Process modeling and simulation - Model debugging and calibration Before applying, please confirm - Your experience with GPS-X and ASM-based models - Whether you have modified or debugged ASM models before (not only used built-in models) - Your estimated time to complete this task - Your expected cost Deliverables - Corrected GPS-X model source files - Short summary document of problems identified and fixes applied

Hi there, I am confident in my ability to assist with your GPS-X / ASM2d wastewater process modeling needs. With extensive experience in wastewater treatment modeling, particularly with GPS-X and ASM2d, I have resolved similar issues where model outputs did not align with expected behavior. I will review your existing ASM2d model implementation, identify discrepancies, and modify the model effectively. My approach will ensure the simulation results are accurate and meet the required standards. Additionally, I will provide a comprehensive summary, detailing the issues found and the changes made during the correction process. I estimate that this task will take about 5 days to complete, and I propose a bid of $25 for the project. Thanks,
