Despite some troubles, COD remains a useful Instrument for monitoring and managing the remedy processes within a wastewater remedy plant and ensuring compliance with environmental laws.
COD is usually a critical indicator of water quality and is also utilized in many different apps, such as the following:
It might be calculated speedily to realize beneficial info on water bodies and industrial or wastewater treatment method plant effluent.
Digestion is done within the samples using a set volume of the oxidant, sulfuric acid, and warmth (a hundred and fifty°C). Metallic salts are usually provided to suppress any interferences also to catalyze the digestion. This digestion ordinarily normally takes two hours to carry out.
The COD test only will take a few hours to finish, providing it A significant advantage in excess of the 5-working day BOD test. Wastewater procedure program staff can use COD as an Virtually serious-time operational adjustment parameter.

It might be outlined as the quantity of oxygen expected by natural and organic make any difference inside of a sample of drinking water for its oxidation by a solid oxidizing agent which is expressed as ppm of oxygen taken from an answer of K2Cr2O7 in two varieties.
Methods specializing in the detection process have not but been absolutely formulated, as their only perform is for making the ultimate reaction additional sensitive.
