Note:

The Food to Microorganism (F/M) Ratio helps in wastewater treatment efficiency by balancing food supply with biomass concentration.

Why Environment-Sector

This Food to Microorganism (F/M) Ratio Calculator belongs to the Environmental Sector Helps in optimizing biological treatment efficiency and ensuring effective BOD remova

Explanation of Parameters:

• Q (Flow Rate): Wastewater entering the system per day (m³/day).
• S₀ (Influent BOD): The BOD (Biochemical Oxygen Demand) concentration in the incoming wastewater (mg/L).
• X (Biomass Concentration): The microorganism concentration in the aeration tank (mg/L).
• V (Tank Volume): The volume of the aeration tank (m³).

Why F/M Ratio is Important?

Maintaining an optimal F/M ratio ensures efficient biological treatment and prevents microbial imbalance.

Validations:

• Positive Values Only: All inputs must be positive numbers.
• Ideal Range: Typical F/M ratio is **0.2 - 0.6 kg BOD/kg MLVSS-day**.
• Too High: Excess food leads to poor treatment efficiency.
• Too Low: Biomass starvation can cause system failure.
