Where:
: Usually ranges from 50 to 80 mm for wastewater and 25 to 50 mm for drinking water. Narrower spacing increases the number of plates but also increases the risk of bridging and clogging by large solids. Core Design Calculations

This is where lamella design differs from conventional clarifiers. The area is not the footprint, but the sum of the projected areas of the plates.
No single, authoritative, free PDF contains all lamella clarifier design calculations. The best “download” is a self-made spreadsheet based on peer-reviewed equations. Let us walk through a practical design scenario
To size a unit correctly, engineers must balance hydraulic load with the settling characteristics of the particles. Lamella Clarifier Design Calculations | PDF - Scribd
