Biochemical oxygen demand - Wikipedia

★ ★ ★ ★ ★

Biological oxygen demand measures the amount of oxygen used by microorganisms in the oxidation of organic matter. When there are too many phosphates in aquatic systems, algae proliferates, dies, and then aerobic bacteria decomposes them, starving the water of oxygen and killing bacteria and other aerobic creatures.

Oxidation, Biological . the aggregate of oxidation reactions that proceed in all living cells. The primary function of biological oxidation is to provide the organism with usable energy. Biological oxidation is catalyzed by enzymes called oxidoreductases. In the 18th century, A. Lavoisier was the first to study oxidation in organisms.

8/27/2018 · Increasing oxidant dose usually will increase demand, but it is incorrect to assume that doubling the oxidant dose will double the oxidant demand. For these reasons, it is difficult to extrapolate oxidant demand data from one set of conditions to another. Always study oxidant consumption under the range of conditions expected in the field.
