Clarifier

Clarifier
A tank in which solids settle to the bottom and are subsequently removed as sludge.
Class I Area ...

Clarifier (sedimentation basin) A tank in which quiescent settling occurs, allowing solid particles suspended in the water to agglomerate and settle to the bottom of the tank. The solids resulting from the settling being removed as a sludge.

clarifier or sedimentation basin .
sediment yield. The quantity of sediment arriving at a
specific location.

Water exiting the flocculation basin enters the sedimentation basin, also called a clarifier. It is a large tank with slow flow, allowing floc to settle to the bottom.

weir diameter Many circular clarifiers have a circular weir within the outside edge of the clarifier. All the water leaving the clarifier flows over this weir.

One of the guidelines for design of the settling tanks and clarifiers in a treatment plant to determine if tanks and clarifiers are used enough.
Oxidation
A chemical reaction in which ions are transferring electrons, to increase positive valence.

Weir: 1. A wall or plate placed in an open channel to measure the flow of water. 2. A wall or obstruction used to control flow from settling tanks and clarifiers to ensure a uniform flow rate and avoid short-circuiting. (See: short-circuiting.) ...

clarifer : A large circular or rectangular tank or basin in which water is held for a period of time, during which the heavier suspended solids settle to the bottom. Clarifiers are also called settling basins and sedimentation basins.

Tube Settler- Device using bundles of tubes to let solids in water settle to the bottom for removal by conventional sludge collection means; sometimes used in sedimentation basins and clarifiers to improve particle removal.
