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

The required effective settling area is determined by the flow rate and the design surface overflow rate:

The bottom of the clarifier must be designed to collect and remove settled solids efficiently, usually via a conical hopper or a mechanical scraper.

Lamella clarifiers, also known as inclined plate settlers, are essential components in modern water and wastewater treatment. They are designed to remove particulates from liquids by utilizing a series of inclined plates, which provide a large effective settling area within a small footprint. This article provides a comprehensive guide to lamella clarifier design calculations, offering insights into the principles, formulas, and practical considerations involved.

Alternatively, if you know the number of plates (N), the total area is:

Let's assume a flow rate of 100 m³/h and a design SOR of 1.0 m/h. The plates are 2 meters long, 1 meter wide, and inclined at 60°. We'll use an efficiency factor of 0.8. Number of Plates:

The dimensions of the individual plates.
