Definition: BOD capacity (refer to waste water treatment plants)
The total quantity of oxygen-demanding material that a wastewater treatment plant is designed for which can be treated daily with a certain efficiency. For secondary treatment plants the BOD5 capacity is mostly limited by the oxygenation capacity, i.e. the quantity of oxygen that can be brought into the water to keep the oxygen concentration on a suitable level.
