[ A_proj = \textTotal plate area \times \sin(\theta) ] lamella clarifier design calculation pdf downloadl better

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. | | Basic PDF | Better PDF |

[ N_plates = \frac\textWidth of clarifier tank\textPlate spacing + \textplate thickness ] No – total

Typical design HLR for lamella clarifiers ranges from (conventional clarifiers: 0.5–1.0 m³/m²·h).

[ Re = \fracV_channel \cdot d_h\nu ]
