CALCULATORS
Calculate sludge age and F/M ratio
Sludge age and the food-to-microorganism ratio (F/M) are the two parameters used to control an activated sludge reactor: how long the biomass stays in the system and how much organic matter it receives per kilo of biomass. They are used to adjust sludge wasting and aeration.
Indicative result. For a diagnosis of your installation, measure continuously or contact us.

How it is calculated
- Sludge age: Age = V · MLSS / (waste flow · waste concentration).
- Food to microorganism ratio (F/M): F/M = Q · BOD₅ / (V · MLSS). Usually 0.05 to 0.3 in activated sludge.
Measure these data continuously
With our IoT probes, sensors and equipment you have the data in real time on any device, and the panel calculates this value on its own and warns you before problems appear.
