Quality dilution drinking water is critical when testing BOD, as any contamination from the water will result in issues with the test.

BOD Evaluation is similar in purpose to chemical oxygen need (COD) analysis, in that both equally measure the amount of natural and organic compounds in drinking water.

For many people an entire comprehension of the conventional methods necessary to properly entire vital wastewater analytical tests will not be required. Even so, a fundamental knowledge of the theory powering, and working familiarity with, the basic procedures utilized for Each and every test and the responses to generally questioned questions on Just about every test generally is a worthwhile Instrument for any person linked to producing, checking, managing, or discharging method wastewater.
