GPS-X / ASM2d Wastewater Process Modeler (Activated Sludge Model Modification)

Job ID: 40178323

Budget: $10 – $30 USD

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
