Biological oxygen demand

BIOLOGICAL OXYGEN DEMAND (BOD) The amount of oxygen needed for aerobic microorganisms to function in organic-rich water such as sewage.
BIOLOGICAL TREATMENT Technology that uses bacteria to consume waste/ organic materials.

Biological Oxygen Demand (BOD) (D):
BOD is a measure of the amount of oxygen consumed by micro-organism in breaking down organic matter in effluent during a certain period.

Biological Oxygen Demand (BOD)
An indirect measure of the concentration of biologically degradable material present in organic wastes.

biological oxygen demand (bod) More correctly, the biochemical oxygen demand. An indirect measure of the concentration of biologically degradable material present in organic wastes.

Biological Oxygen Demand
The amount of oxygen required by aerobic biological processes to break down the organic matter in water. BOD is a measure of the pollutional strength of biodegradeable waste on dissolved oxygen in water.

BOD Biological Oxygen Demand
This is the amount of oxygen taken from the water by all processes - mainly biological. Some pollutants demand this oxygen, thereby depriving other biological processes.

Biological Oxygen Demand
The amount of dissolved oxygen consumed in five days by biological processes breaking down organic matter.

Secondary treatment. Generally, a level of treatment that produces 85 percent removal efficiencies for biological oxygen demand and suspended solids. Usually carried out through the use of trickling filters or by the activated sludge process.

Suspended solids (SS): Defined in waste management, these are small particles of solid pollutants that resist separation by conventional methods. Suspended solids (along with biological oxygen demand) are a measurement of water quality and an ...
