Settle-O-matic™ — Settling Case Gallery
Six representative activated-sludge settling cases captured by the Settle-O-matic™ Analyzer —
each shown as a 40-minute time-lapse, its measured settling curve, and stage frames (SV0/SV5/SV30/SV40) with a
clean-jar reference. SV = settled sludge volume (mL).
Normal — Session 9918
WWRP-A20 · SV5 811 · SV30 338 · SV40 299 mL · Steady settling to a defined blanket.
