An industrial wastewater plant requires a lamella clarifier to process a flow rate ( ) of . The target particle settling velocity ( νsnu sub s ) is calculated as . Chosen Plate Dimensions: Chosen Plate Angle: 60∘60 raised to the composed with power Step-by-Step Execution: Calculate Required Effective Area ( Aeffcap A sub e f f end-sub ): Calculate Effective Area Per Single Plate ( Asinglecap A sub s i n g l e end-sub ): Determine Total Number of Plates ( ):

) and length are derived from the plate dimensions and the number of plates. Tank Width ( Approximately calculated as is plate length). Total Spacing: The total horizontal length required for the plate pack is 5. Sludge Hopper Design

Once particles settle onto a plate, gravity causes them to slide down into a collection hopper at the bottom of the unit. Lamella Clarifier Design Calculation Pdf Downloadl

Using Stokes' Law, the theoretical settling velocity of a spherical particle in laminar flow is calculated as:

Identify the maximum hourly flow rate the system must handle, typically measured in cubic meters per hour (m³/h). 2. Select the Surface Overflow Rate (v)

Lamella clarifiers, also known as inclined plate settlers, are high-efficiency water treatment units designed to remove suspended solids from liquids. By using inclined plates, they provide a much larger settling area within a smaller footprint compared to conventional clarifiers. ): The width of the plate pack, determined by tank geometry

The angle at which the plates are inclined. An angle of 55° to 60° is common to ensure solids slide down the plates by gravity.

Manually performing these calculations each time is tedious and prone to error. You need a standardized, pre-tested template.
