1. Deciding on the goals of the model - and if more than one goal is targeted then prioritization of set goals.
- How do you imagine the model to work?
- What is it that is wanted to be found out? I.e. Process operation change, capacity assessment, retro fit
- Which of the unit processes are to be focused on?
- Of any problems found, what are encountered most often?
- Where is the vast majority of the allocated budget going?
- Operational parameters
- Physical dimensions of the Tank
- Unit Interconnections
3. Preparation and Conduction of a Sampling Program (optional but highly recommended)
This allows the engineer to become acquainted with plant personnel and how the treatment plant operates:
- Obtain a site plan or diagram of the Plant
- Ensure the co-operation and understanding of Plant personnel
- Anticipate any variations in Plant performance, plan in advance and keep personnel informed
- Enquire about laboratory testing if deemed necessary
- Observe thoroughly the operation of the Plant, being sure to take written notes
- Screen Data
- Mass Balances
- Design hand calculations
5. Model Calibration and Set Up
- Define each process unit in regards to chemical, physical and operational parameters
- Adjust model predictions until the information matches the Plant data performance
7. Model Simulations such as
- Assessment of feasibility
- Loading conditions
- Analysis of Aeration
- Management of Solids
- Removal of Biological nutrients
