Sedimentation Tank Sizing
Estimate clarifier surface area, equivalent circular diameter, water volume, and hydraulic detention time from flow, surface overflow rate, and depth.
OPERATING LIMITS — Hydraulic clarifier calculation only; verify settling tests, solids loading, sludge storage, inlet/outlet hydraulics, weir loading, redundancy, and local design criteria.

Technical Methodology & Engineering Principles
GOVERNING EQUATION
Surface area = flow / surface overflow rate; volume = surface area × side-water depth; detention time = volume / flow.
Assumptions & Scope
Hydraulic sizing screen only; verify settling tests, solids flux, inlet/outlet hydraulics, weir loading, sludge storage, scum removal, redundancy, and local water-treatment design criteria.
Operating Range & Boundary
Use finite, physically meaningful inputs within the stated operating assumptions.
