This is the terminal settling velocity of the target particle. Stoke’s Law is the foundation:

The critical velocity is the maximum upward velocity allowed for a particle to be captured. The core of lamella clarifier design relies on the theory

A typical design calculation follows these steps (based on standard industry procedures):

Aeff=N⋅(L⋅W)⋅cos(θ)cap A sub e f f end-sub equals cap N center dot open paren cap L center dot cap W close paren center dot cosine open paren theta close paren : Number of plates. : Length of the plates. : Width of the plates. : Angle of inclination (typically 55°–60°). Step 2: Surface Loading Rate (SLR) Stoke’s Law is the foundation: The critical velocity

Mastering lamella clarifier design calculations is essential for engineers and treatment plant operators who want space‑efficient, cost‑effective sedimentation. By understanding the shallow‑depth sedimentation principle, applying the correct formulas, and using proven resources—especially the free PDFs, Excel workbooks, and manufacturer data linked above—you can confidently size and specify a lamella clarifier that meets your flow, solids loading, and effluent quality requirements.
