Fascination About COD testing

It consists of using electrodes as well as the measurement of electrical potential, existing, or impedance to find out the concentration or Qualities of sure compounds or ions in water.

Chemical oxygen demand is definitely an index of pollution that steps the effect of pollutants on dissolved oxygen. From the COD test, an oxidant in addition to O2 is used to degrade the pollutants while in the h2o sample.

This value is a inadequate evaluate on the toughness of natural issue as oxygen also gets consumed in the oxidation of inorganic make a difference including nitrates, sulfates, and diminished steel ions, as well as that some natural components like benzene pyridine and a few other cyclic organic and natural compounds do not get oxidized by this test.

A very good COD stage might be 0mg/l, but is probably not possible for most treatment method procedures to attain. Commonly a suitable highest COD discharge Restrict will likely be set through the nearby governing body e.g. Ecosystem Agency or H2o Utility Organization.
