 Process Analysis – OPTISENS ODO 2000
 
Optical dissolved oxygen sensor for waste water analysis
 
Optical dissolved oxygen sensors are widely used to control and monitor oxygen concentration during the biological treatment of sewage water.
 
The dissolved oxygen sensor OPTISENS ODO 2000 from KROHNE has a standardized robust design and a long lifespan. Therefore the sensor is especially designed for small and medium-sized wastewater treatment plants, where regular calibration and cleaning of the sensors is difficult due to limited maintenance resources.
 
OPTISENS ODO 2000's use of the optical principal interacting with a fluorescent membrane means there's no need for recalibration. Precision and reliability remain constant. The integrated spray cleaning system minimizes the need for manual cleaning, which means longer intervals between maintenance.
 
Highlights
 
  • No recalibration necessary
  • Reliable measurement via fluorescence measurement
  • Fast response time in all application
  • No media flow required
  • Long-term stability due to reduced clogging by integrated spray cleaning system
  • Low cost of ownership
  • Suitable for installation with telescopic rod SENSOFIT IMM 2000

Industries
  • Waste water industry

Applications
  • Monitoring the oxygen content in mg/l in aeration basins
  • Controlling biological treatment in aeration basins, which can also be combined with measuring nitrate and ammonium
