I’m working on a senior project that involves giving recommendations for the placement and control strategy of Dissolved Oxygen (DO) and Oxidation-Reduction Potential (ORP) sensors in an oxidation ditch system used for biological wastewater treatment.
The oxidation ditch in question has the following characteristics:
Aside from the plan/layout of the oxidation ditch, I don’t have access to further design documents (e.g., detailed CFD models or flow velocity measurements).
As someone new to this field, I’m struggling to find clear guidance in the literature on how to approach sensor placement and control zone design in this type of system. Most papers I found focus on modeling but not on practical sensor deployment strategies.
What principles or practical guidelines can I follow to decide where to place DO and ORP sensors for effective aeration control in a carousel-type oxidation ditch?
I would appreciate any references, case studies, or personal experiences with similar systems. Thanks in advance!
The oxidation ditch in question has the following characteristics:
- Geometry: Carousel-type
- Aeration system: Fine bubble diffused air
- Mixing: Pulsatile mixing system
- Tank depth: 5.2 m
- Maximum volume: 11,425 m³
- Channel width: 27.7 m
- Air flowrate: 40,681.5 m³/h
