The quantity of dissolved oxygen in water (mg/l) consumed under test conditions during a given period (5 days) through the microbiological oxidation of biodegradable organic matter present in wastewaters. One of the standard tests used to characterise effluent quality.

The amount of oxygen

The amount of dissolved oxygen consumed by micro-organisms (bacteria) in the bio-chemical oxidation of organic and inorganic matter in waste water.

Biochemical Oxygen Demand — BOD A measure of the oxygen required to break down organic materials in water using biological means. The amount of oxygen required to oxidize any organic matter present in water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in water that is used to m [..]

A measure of the amount of oxygen consumed in the biological processes that break down organic matter in water. The greater the BOD, the greater the degree of pollution.

A measure of the amount of oxygen consumed in the biological processes that break down organic matter in water. The greater the BOD, the greater the degree of pollution.

The amount of dissolved oxygen used by organisms during the decomposition of organic matter, expressed as mass of oxygen per volume of water, over some specified period of time.

The dissolved oxygen required to decompose organic matter in water. It is a measure of pollution since heavy waste loads have a high demand for oxygen.

A quantitative measure of the oxygen needed by bacteria and micro-organisms for the biological oxidation of organic wastes in a unit volume of waste water. BOD is generally measured in milligrams per litre (mg/l) of oxygen consumed over a five day period. Although complete biological decomposition of organic waste requires about 20 days, the five d [..]

(BOD) The quantity of oxygen utilized in the metabolism of organic matter in a specified time and at a specified temperature. It is determined by the availability of a material as a biological food and by the amount of oxygen utilized by the microorganisms during oxidation.

See BOD.

BOD is the measure of the amount of oxygen required by bacteria to stabilize material that decomposes under aerobic conditions. BOD is a commonly used determinant of the organic strength of a waste, as it serves as an indicator of the waste’s capacity to remove oxygen from water.  Oxygen concentrations in water determine the quality of fish and oth [..]

The amount of oxygen consumed in the oxidation of organic matter by biological action under specific standard test conditions. Widely used as a measure of the strength of sewage and wastewater.

the amount of molecular oxygen in water that is consumed by micro-organisms during the process of decomposition. BOD is used as an indicator of water pollution from organic wastes.

The quantity of oxygen used in the biochemical oxidation of organic matter. Usually expressed in mg/L. If the BOD is high, the dissolved oxygen levels in the water will be low.
