WATER QUALITY MONITORING PARAMETERS
COD Monitoring
Online COD monitoring for wastewater discharge, industrial effluent and environmental water applications.

COD Monitoring Overview
Chemical Oxygen Demand (COD) is widely used to indicate the amount of oxidizable organic matter in water. It is a standard parameter in wastewater treatment and discharge monitoring.
COD is typically measured with reagent-based online analyzers. The analyzers can be integrated into monitoring stations and connected to data acquisition and remote monitoring systems.
Why Monitor COD?
Continuous COD measurement helps operators understand changing water conditions and respond earlier.
Wastewater
COD is a core parameter for treatment performance and discharge control.
Industrial Water
Effluent COD monitoring supports discharge compliance.
River & Lake
COD helps assess organic pollution in surface water.
Water Treatment
Source water COD monitoring supports process adjustment.
Agricultural Water & Runoff
Organic load assessment in drainage and runoff.
Aquaculture
Organic load indication in intensive production water.
How COD Is Monitored
COD can be measured with different equipment depending on the application and monitoring environment.
Online COD Analyzers
Reagent-based online analysis for continuous COD measurement.
UV-Based Measurement
Where applicable, UV methods can provide reagent-free organic matter indication.
Multi-Parameter Analyzers
COD can be combined with ammonia nitrogen, TN and TP analysis.
Monitoring Stations
Analyzer integration into outdoor or cabinet monitoring stations.
COD Monitoring Applications
Select the application closest to your monitoring requirement.
Wastewater
Influent, process and effluent COD monitoring.
Industrial Water
Industrial effluent COD monitoring at discharge points.
River & Lake
COD monitoring for pollution assessment in surface water.
Water Treatment
Source water monitoring where organic load is a concern.
Agricultural Water & Runoff
Organic load assessment in drainage and runoff water.
COD Monitoring Equipment
Equipment options for measuring COD in online monitoring systems.
