YES. While COD need to be thought of an unbiased test from BOD, and may deliver an increased concentration studying than BOD for a particular wastewater sample, it is normally acknowledged that COD and BOD share an empirical partnership.

Investigating the BOD amounts at diverse details during the h2o physique can help pinpoint the supply of air pollution.
TPP is stuffed with illustrative information instead of relevant to any merchandise in the marketplace or in improvement.

Complete BOD is of a lot more significance to meals webs than to drinking water quality. Dissolved oxygen depletion is probably to be apparent in the course of the Original aquatic microbial population explosion in reaction to a large amount of organic and natural materials.
