Determine how much total projected area is needed to achieve the target settling.
Even with perfect calculations, real-world performance can be influenced by:
For detailed spreadsheets, calculation sheets, and diagrams, you can download reference materials from the following sources:
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. Lamella Clarifier Design Calculation Pdf Downloadl
This article provides a complete guide to lamella clarifier design calculation. We'll cover the working principle, key design formulas, step-by-step calculation procedures, and practical design considerations. You'll also find information about downloadable PDF documents and Excel-based design spreadsheets that can help you perform your own calculations.
DT=VQcap D cap T equals the fraction with numerator cap V and denominator cap Q end-fraction : Total volume of the clarification zone.
Divide the total required effective area by the area of a single plate: Determine how much total projected area is needed
: Includes formulas for settling velocity and total projected surface area calculations.
Select a suitable SOR based on the settling characteristics of the particle (e.g., flocculent settling vs. granular settling). Typical Range: 3. Calculate Required Effective Settling Area ( Areqcap A sub r e q end-sub

Using Stokes' Law, the theoretical settling velocity of a spherical particle in laminar flow is calculated as:
High-speed sedimentation due to reduced settling distances. Modular: Easy to scale up. Fundamental Design Principles
