. By utilizing a series of inclined plates, these systems achieve settling areas up to 95% larger than conventional clarifiers within the same physical footprint. Core Design Principles The effectiveness of a lamella clarifier is governed by Stokes’ Law for particle settling velocity and Hazen’s Load Theory Effective Settling Area ( cap A sub e f f end-sub
To find the total plate area required for a specific flow and particle settling velocity:
The core of a lamella clarifier's design involves determining the number, size, and configuration of plates to achieve the required surface area.
The design of a lamella (inclined plate) clarifier relies on maximizing the within a small physical footprint. Effective Settling Area ( Aeffcap A sub e f f end-sub
) is calculated using the horizontally projected area of all the plates:
The search for a "lamella clarifier design calculation pdf download" is common because engineers value ready-made tools. Finding a single PDF may be difficult, but the following resources offer excellent design assistance:
Collects settled solids at the bottom. The distance between the bottom of the plates and the sludge hopper must be sufficient to prevent re-entrainment.
While text files cannot be downloaded directly here, below is the for a superior design spreadsheet. You can copy this into Excel to create your own dynamic calculator.
To guarantee long-term operational stability and prevent premature clogging or particle carryover, perform verification checks on the flow velocity and loading rates. Surface Overflow Rate (SOR) Check

for self-cleaning (sludge slides down smoothly via gravity). Step 5: Determine the Number of Plates Calculate the individual plate length ( ) and width (
Once collected on the plates, the solids slide down the incline into a sludge hopper at the bottom.
