UV254 Monitoring for Organic Content
UV absorbance at 254 nm (UV254) is used to estimate the concentration of dissolved organic matter (DOM) in water. Continuous monitoring provides real-time insight into organic load, supporting process control, treatment efficiency and regulatory compliance.
Real-Time Organic Monitoring & Control
UV254 monitoring systems provide continuous measurement of organic content, enabling operators to respond quickly to changes in water quality and optimise treatment processes.
Correlation with Key Water Quality Parameters
UV absorbance can be used as a surrogate measurement for several key indicators of organic pollution:
- Biochemical Oxygen Demand (BOD)
Indicates the level of biodegradable organic matter in water - Chemical Oxygen Demand (COD)
Measures the total oxygen required to oxidise organic material - Dissolved Organic Carbon (DOC)
Estimates the concentration of dissolved organic compounds - Total Organic Carbon (TOC)
Provides an overall indication of organic carbon content
Benefits of Continuous UV254 Monitoring
- Real-time insight into organic load
- Early detection of changes in water quality
- Improved control of treatment processes
- Reduced reliance on laboratory testing
- Support for compliance and operational efficiency
By using UV254 as a surrogate measurement, operators can gain fast, reliable insight into organic content, helping to improve process control and maintain consistent water quality.
