Settlement lagoons, tanks and clarifiers

• Settlement tanks and settlement lagoons work in a similar way

• To be captures a particle must fall to the base of the tank before it
travels the length of the tank.

• The flow rate which you can treat is defined by the following equation:

Q = V x A

3
Q = Flow Rate (m /hr)
V = Particle Settling Velocity (m/hr)
2
A = Effective Settlement Area (m )
