Effluent launders should handle < 12 m³/h per meter of weir. With 30 m³/h, need weir length > 2.5m. The 17-plate pack (each 1m wide) provides side weirs summing to ~17m – more than enough.
Use design Vs = 1.5 m/h. A_proj needed = 30 / 1.5 = 20 m². Plates: 20 m² per plate? No – total. With 1.23 m²/plate, need 20/1.23 ≈ 17 plates. Much more realistic. lamella clarifier design calculation pdf downloadl better
[ Re = \fracV_channel \cdot d_h\nu ]
[ A_proj = \textTotal plate area \times \sin(\theta) ] Effluent launders should handle < 12 m³/h per
Where (\theta) is the inclination angle (typically 50–60° from horizontal). Effluent launders should handle <
Area = Flow rate / Vs = 30 m³/h / 14.3 m/h = 2.10 m² (ideal). Add safety factor 1.5 → 3.15 m²
