Biological oxygen demand definition

Biological oxygen demand means the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five days at 20 de- grees C., expressed in parts per million by weight.
Biological oxygen demand means biological oxygen demand (BOD) measured after 5 days at 20ºC with nitrification suppressed by the addition of allyl-thiourea.
Biological oxygen demand or “BOD.” means biochemical oxygen demand, which is the quantity of oxygen utilized in the biochemical oxidation of organic matter in five days at twenty degrees Celsius under standard laboratory procedure expressed in milligrams per liter. A single- family residence is generally considered to have a BOD of less than or equal to 300 mg/l.
