AMI Trides – Monitoring of Residual Disinfection After UV Treatment
In water treatment systems using UV disinfection, it is important to verify that the process delivers sufficient microbial inactivation while maintaining a controlled residual disinfectant level.
The SWAN AMI Trides analyzer provides continuous monitoring of residual disinfectants such as chlorine or chlorine dioxide after UV treatment. This ensures that disinfection remains effective throughout the distribution system.
With reliable monitoring, you can maintain safe water quality and stable disinfection control.

Monitoring residual disinfectants after UV disinfection
UV systems are widely used for primary disinfection, but they do not provide a lasting residual effect in the water.
The AMI Trides is designed to measure residual disinfectants downstream of UV systems, ensuring that:
- a sufficient disinfectant residual is maintained
- microbial regrowth is prevented
- water quality remains stable in the distribution system
The analyzer typically uses colorimetric photometric measurement, providing accurate and reliable monitoring of disinfectant levels.
Why residual monitoring after UV matters
While UV effectively inactivates microorganisms, it does not leave a residual disinfectant in the water.
Without proper monitoring and control, this can lead to:
- microbial regrowth in distribution systems
- unstable water quality
- insufficient disinfection in downstream processes
By monitoring residual disinfectants, you can ensure continuous protection and maintain safe water conditions.
Key features supporting stable disinfection control
- Continuous online measurement of residual disinfectants after UV treatment
- Suitable for chlorine, chlorine dioxide, or similar oxidants
- Accurate colorimetric photometric measurement technology
- Automatic reagent dosing and measurement cycles
- Stable and repeatable measurement results
- Adjustable measurement intervals for optimized operation
- Integrated diagnostics and alarm functions
- Industrial communication interfaces for process control
These features help ensure consistent disinfection performance and reliable water quality monitoring.
Typical applications in water treatment systems
The AMI Trides analyzer is used in systems where UV disinfection is combined with chemical disinfection.
Typical applications include:
- Drinking water treatment plants
- Municipal water distribution systems
- Swimming pools and public water facilities
- Industrial water treatment systems
- Process water systems requiring controlled disinfection
Monitoring residual disinfectant levels ensures that water remains safe after UV treatment and throughout the system.
Benefits for your operation
With reliable residual disinfectant monitoring you gain:
- Continuous verification of disinfection performance
- Improved control of chemical dosing
- Stable water quality throughout the system
- Reduced risk of microbial regrowth
- Optimized use of disinfectants
These benefits support safe, efficient, and compliant water treatment operations.
