Ammonia and Nitrate Measurement in
Municipal Wastewater Applications
Advantages of the Advanced Sensor Technology real-time continuous online measurement systems for ammonia and nitrate
- Low Initial Procurement Cost compared to competing technologies and offerings
- No need for chemical feed and rebuilding of sensors
- Lower Cost of Ownership due to very long sensor lifetime, low maintenance & cleaning requirements for inline, immersion & submersion ion selective sensors
- Intuitive and easy to use Rosemount 1056 and 1057 analyzer programmed and configured for ammonia and nitrate ion selective analysis
- All new systems come preconfigured, precalibrated and fully qualified to install, plug-in and immediately place into service especially for compliance purposes
- Only periodic 1-point grab sample offsetting is required – this “Standardize” calibration can be performed WITHOUT removing sensor from service!

Ammonia Sensor and Nitrate Sensor with Significantly Improved. Selectivity Over Respective Interfering Ions Potassium & Chloride
Ammonia Sensor and Nitrate Sensor with Significantly Improved
Selectivity Over Respective Interfering Ions Potassium & Chloride
- Capability to measure below 1ppm ammonium (total ammonia or NH3-N) in presence of common levels of potassium for secondary WWTP
- Capability to measure nitrate (NO3-N) even in the presence of high levels of chloride or nitrite ions without loss of linearity or stability
- Ammonia and nitrate measurements can be performed using just one analyzer
- Support for dual ammonia/ammonia, nitrate/nitrate configurations and ammonium/nitrate configurations to minimize cost per channel as well as triple channel ISE, pH and ORP measurement configurations
- No potassium ion “compensation” required for ammonium ion selective sensors and no chloride ion “compensation” required for nitrate ion selective sensors for most common WWTP applications, due to substantial improvements using novel proprietary technology developed from ASTI research and extensive field trials to ensure performance in actual measurement conditions of interest
- Support for dual ammonium/pH systems to determine total ammonia at any given pH for any given temperature within the permissible range
