Webinar | How to Choose the Correct Sensor for Online Nutrient Monitoring

September 06, 2022

Wastewater expert Ben Barker briefly introduces nutrient monitoring in wastewater and discusses the measuring technologies for ammonium, nitrate, and phosphorus. 

Nutrients are quickly becoming a primary concern for wastewater facilities, and modern sensor manufacturers have responded by improving instrumentation for online nutrient monitoring. Sensors and analyzers for ammonium, nitrate, and phosphorus are increasingly used to monitor and optimize the nutrient removal process. Still, operators and engineers are faced with multiple measuring technologies for each. Each type of sensor or analyzer has advantages and disadvantages; some sensors will fit applications better than others. Learn how to decide which sensor type works best for your facility when deciding between multiple measuring technologies.

Technology comparisons:

  • Ion-selective electrode (ISE) sensors vs. wet-chemistry analyzers for ammonium measurement
  • ISE vs. UV sensors for nitrate measurement
  • Differences between orthophosphate and total phosphorus measurement

Learn how to: 

  • Identify the different types of sensors and analyzers available for online nutrient monitoring.
  • Describe the differences between measuring technologies for ammonium, nitrate, and phosphorus.
  • Apply nutrient sensors to the correct application when faced with multiple options.

Who should watch:

Water treatment engineers, operators, instrument technicians, and superintendents who want to learn more about online instrumentation and sensor applications.
