ODM-100 Oxygen Demand Monitor
The ODM-100 Oxygen Demand Monitor is a portable unit for measuring real-time oxygen demand at any point in a wastewater treatment process.
Flexible & easy to use
- Can be placed at any point in the treatment process to monitor biological activity
- Stationary or portable installation
- Continuous or sequential batch mode
- Touch-sensitive menus
Trouble-free operation
- Robust instrument, designed for operation in harsh wastewater environments
- Proprietary anti-clog methods
- Minimal maintenance required
How it works
- Wastewater can be added to the Reactor Vessel from the influent stream, or mixed liquor can be sampled directly from an aeration basin
- Oxygen uptake rate data is sent to a 4-20mA output (suitable for SCADA systems), is stored in memory, and can be downloaded via USB memory stick for subsequent processing
- The data file includes oxygen uptake rate in milligrams/liter/hour and the time and date of data recording
Applications
- Treatment process monitoring
- Trend monitoring for daily and seasonal optimization of processes
- Rapid assessment of changing oxygen demand in an aeration basin
- OUR fingerprint analysis
- Optimizing aeration, nitrification, denitrification, RAS ratios and overall aerobic digestion efficiency
- Stand-alone batch testing of trucked-in or industrial wastewater
- Evaluate treatability and possible toxic events
