Activated sludge and clarifiers: wastewater treatment plants in Florida
50 plants · 83% of the state · 135 MGD reported by 35 plants
Klarifi identifies 50 publicly owned wastewater treatment plants with activated sludge and clarifiers in Florida, 83% of the 60 plants in the state (135 MGD reported by 35 plants). The largest is Jea Buckman WWTP in Jacksonville at 24.34 MGD.
Activated sludge is the standard mechanical process for cities: aeration basins where bacteria consume organic matter, followed by clarifiers that settle the biomass out. These plants are identified by their circular or rectangular clarifiers and by the suspended-growth process code, and they are the main market for blowers, diffusers, clarifier mechanisms and instrumentation.

Sources and methodology
Flow, permit and violation figures come from the EPA's ICIS-NPDES discharge monitoring records. Population served comes from the Clean Watersheds Needs Survey 2022. Treatment structures are identified by Klarifi's review of aerial imagery, and capital improvement projects are extracted from published municipal budget documents. Violations are counted over the last three years of monitoring reports.
