DESIGN F/M RATIO

The F/M ratio calculation is just one of the process control parameters you should monitor in your activated sludge system. The following are suggested operating parameters for F/M Ratio. The optimum F/M ratio for your plant can only be determined by monitoring facility performance through regular process control testing.

Conventional Activated Sludge (F/M) 0.2  -  0.5
Contact Stabilization (F/M) 0.15  -  0.2
Extended Aeration (F/M) 0.01  - 0.07
Step Aeration (F/M) 0.2  - 0.5
Two-Stage Aeration (F/M) 0.07  -  0.15
