Lamellar settling tank: settled water collection
Input data
Water temperature
Incoming flow
Number of settling tanks in parallel
Trough width (b)
Trough height (h)
Trough length (L)
Number of sides from which settled water is collected
Number of troughs per settling tank
Output data
Flow per length of collected settled water:
Estimated number of triangular weirs for collecting settled water
Water height in each triangular weir (according to Thomson's formula)
Maximum water height in the trough
Free height over maximum level
Critical height at the trough outlet (hc)
Description
Calculate the capacity of lamellar settling tanks from their inlet flow and geometry.
Note: This calculation assumes that the troughs have free discharge. For submerged discharges, use the following calculation: https://voimatoolbox.com/en/calculations/rectangular-section-trough
