WebAug 7, 2024 · What is the ratio of COD to BOD? 0.3 to 0.8 Typical values for the ratio of BOD/COD for untreated municipal wastewater are in the range from 0.3 to 0.8 (see in table 3). If the BOD/COD ratio for untreated wastewater is 0.5 or greater, the waste is considered to be easily treatable by biological means. WebCOD vs. BOD Methods for Testing Water Quality. Of the two tests, COD analysis is more commonly performed as it takes less time and is more replicable. Furthermore, treatment operators can quickly react to changes in oxygen demand and modify treatment processes appropriately. Plant engineers may establish a statistically validated COD/BOD ratio ...
