Simple OpenFOAM simulation for wastewater treatment

I am looking for a freelancer who can help me with a simple OpenFOAM simulation for wastewater treatment.

Specific wastewater treatment process: Filtration

Model: I have a rough idea of the model that I would like to use for the simulation.

Expected outcome from the simulation: Understanding the retention time based on different configurations of the filtration zone.

Skills and experience required for the job:
- Strong knowledge and experience in OpenFOAM simulation
- Familiarity with wastewater treatment processes
- Understanding of filtration processes
- Ability to analyze and interpret simulation results
- Attention to detail and accuracy in modeling and simulation
- Strong problem-solving skills
- Excellent communication skills to discuss and refine the simulation model and results.
