Alternatively, if you know the number of plates (N), the total area is: Lamella Clarifier Design Calculation Pdf Downloadl

The primary principle behind a lamella clarifier is to increase the available settling area without increasing the vessel's physical size. By installing plates at an angle (usually between 45° and 60°), the effective settling area becomes the sum of the horizontal projections of all the plates. This allows for a much higher loading rate compared to conventional horizontal flow clarifiers. Key Design Parameters Ap=W⋅L⋅cos(θ)cap A sub p equals cap W center

The volume of water to be treated per unit of time (e.g., m³/h or GPM).

To find the number of plates required for a specific plate size:

Also known as the rise rate, this is the flow rate divided by the effective settling area. It is typically expressed in m/h or GPM/ft².
