Detention time: The actual time that a small amount of water is in a settling basin or flocculating basin. In storage reservoirs, it means the length of time water will be stored.
Detergent: A water-soluble cleansing agent, other than soap.
Detention Time: 1. The theoretical calculated time required for a small amount of water to pass through a tank at a given rate of flow. 2. The actual time that a small amount of water is in a settling basin, flocculating basin, or rapid-mix chamber. 3.
detention time 1) The theoretical (calculated) time required for a fixed amount of water to pass through a tank at a given rate of flow. 2) In storage reservoirs, the length of time water will be held before being used. 3) The actual time in hours, minutes, ...
detention time the time allowed for solids to collect in a settling tank. Theoretically detention time is equal to the volume of the tank divided by the flow rate.

well or surface seals, or layers of high permeability geologic materials. Also when some of the water in tanks or basins flows faster than the rest; usually undesirable since it may result in shorter contact, reaction, or settling times in comparison with the calculated or presumed detention times.
