Chemical Oxygen Demand is a sum measure of all the organic material in a water sample that can be oxidised by a specific combination of chemicals. Online COD measurement using the UV absorbance method is a well established alternative to the traditional dichromate lab method.
COD measurement via UV absorbance measures the organic material that can absorb UV light and a certain amount of calibration on site is required in order for it to correlate with the dichromate standard method.
An alternative method that uses ultrasonic wave velocity can also be utilised and tends to be used in applications where Chemical Oxygen Demand (COD) is higher such as in breweries.

Grab samples to demonstrate compliance with COD discharge consents are a common way for breweries to manage their wastewater, but there are several advantages to be had by using online COD monitoring.
Ensuring compliance with any COD discharge consents is an important part of a manufacturers monitoring regime, in this case study, the dairy went further and reduced product loss.
