Using Stoke’s Law with dp = 60 µm (0.00006 m), ρp=1200 kg/m³, ρw=998, µ=0.001 Pa·s: Vs = (9.81 × (6e-5)² × (202)) / (18 × 0.001) = ~0.00396 m/s = 3.96 mm/s (or ~14.3 m/h)

In the world of industrial wastewater treatment and potable water clarification, space is money, and efficiency is survival. Traditional sedimentation basins, while effective, consume vast footprints. Enter the (also known as an inclined plate settler or tube settler). By stacking settling surfaces at a 45- to 60-degree angle, this technology reduces the required footprint by up to 90% compared to conventional clarifiers. lamella clarifier design calculation pdf downloadl better

Industrial plant discharges 400 m³/day of wastewater (peak hour = 30 m³/h). TSS = 200 mg/L, particle density = 1.2 g/cm³, water at 20°C. Desired effluent TSS < 50 mg/L. Using Stoke’s Law with dp = 60 µm (0

[ A_proj = \textTotal plate area \times \sin(\theta) ] By stacking settling surfaces at a 45- to

A lookup table for spacing based on sludge type (e.g., 50 mm for light floc, 75 mm for heavy grit). 2.5. Reynolds Number (Re) per Channel Laminar flow is mandatory. For flow between parallel plates:

[ Re = \fracV_channel \cdot d_h\nu ]

[ V_s = \fracg (d_p)^2 (\rho_p - \rho_w)18 \mu ]
