What are you separating (e.g., chemical floc, heavy sand, biological sludge)?
The design of a lamella clarifier is primarily governed by the Surface Overflow Rate (SOR) Effective Settling Area 1. Required Settling Area ( What are you separating (e
The core of lamella clarifier design is calculating the required number of plates to achieve the target surface loading rate. A. Key Design Parameters Surface Loading Rate ( SLRcap S cap L cap R Uacap U sub a ): Inclination Angle ( ): Plate Spacing ( ): Typically Plate Length ( ) and Width ( ) B. The Core Calculation Formula The total effective settling area ( Aeffcap A sub e f f end-sub ) is calculated by multiplying the number of plates ( ) by the horizontal projection of each plate.
