WebBiochemical oxygen demand, otherwise known as biological oxygen demand, is an important parameter in water treatment. When effluent wastewaters are discharged into the environment, they can introduce pollution in the form of organic content to receiving waters. High concentrations of organics can deplete dissolved oxygen levels in water ... WebThe key difference between the two is that chemical oxygen demand measures everything that can be oxidized, whereas biochemical oxygen demand only measures the oxygen demanded by organisms. BOD measures the amount of dissolved oxygen that aerobic biological organisms require to break down organic material.

WebThe BOD test is a method-defined (empirical) technique. Consequently, the method must be followed carefully, and must be performed consistently from day to day and analyst to analyst. Potential errors can be encountered in each of the following steps in the BOD test. Evaluate the results of samples, GGA, blanks and duplicates and report. Weboxygen demand of seed (if used) and the erratic oxygen demand of the dilution water. This system eliminates the need for running an incubated five-day dilution water blank. It also allows the use of dilution water having an oxygen demand > 0.2 mg/L without losing accuracy of the BOD measurement of the unknown samples. Such a flowcchart symbols
BOD Basics Wisconsin DNR
WebBiochemical oxygen demand (BOD) is a measure of the amount of oxygen required by aerobic bacteria and microorganisms for decomposing organic matter present in wastewater over a period of five days. BOD gives an estimate of the water quality and is measured in milligrams per liter (mg/l) or parts per million (ppm). WebBiochemical Oxygen Demand, or BOD, is a measure of the quantity of oxygen consumed by microorganisms during the decomposition of organic matter. BOD is the most commonly used parameter for determining the oxygen demand on the receiving water of a municipal or industrial discharge. BOD can also be used to evaluate the efficiency of treatment ...
