oxygendemanding
Oxygen-demanding, in scientific usage, refers to substances, processes, or organisms that require molecular oxygen to function or to release energy via oxidation. In environmental science, the term is commonly applied to biodegradable organic matter and the microorganisms that oxidize it, which consume dissolved oxygen (DO) in the surrounding water.
In aquatic systems, high oxygen demand can reduce available DO and lead to hypoxic or anoxic conditions,
In wastewater treatment and water quality assessment, oxygen-demanding waste includes sewage and biodegradable organics from industry
Management aims to minimize oxygen demand before discharge to protect aquatic ecosystems, using pretreatment, aeration, and
