Question

what is BOD and COD.??

And How us measured??​

Answer 1

Explanation:

Hello...

BOD :

Called Biochemical Oxygen Demand is supposed to measure the amount of food (or organic carbons) that bacteria can oxidize.

COD :

Called Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized. TOC or Total Organic Carbon is the measurement of organic carbons.

How is BOD and COD measured?

It measured by the amount of organic compounds in water. However, COD is less specific, since it measures everything that can be chemically oxidized, rather than just levels of biodegradable organic matter.
