Net Waste Activated Sludge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Net Waste Activated Sludge = Observed Cell Yield*Average Daily Influent Flow Rate*(Influent Substrate Concentration-Effluent Substrate Concentration)*8.34
P_x = Y_obs*Q_a*(S_o-S)*8.34
This formula uses 5 Variables

Variables Used

Net Waste Activated Sludge - (Measured in Kilogram per Second) - Net Waste Activated Sludge is the amount of waste product that can be treated using the activated sludge process.
Observed Cell Yield - Observed Cell Yield refers to the observed mg of cells produced per mg organic matter removed.
Average Daily Influent Flow Rate - (Measured in Cubic Meter per Second) - Average Daily Influent Flow Rate is the total discharge that comes in the reactor.
Influent Substrate Concentration - (Measured in Kilogram per Cubic Meter) - Influent Substrate Concentration refers to the concentration of organic matter or nutrients in the raw wastewater entering a treatment plant.
Effluent Substrate Concentration - (Measured in Kilogram per Cubic Meter) - Effluent Substrate Concentration refers to the concentration of organic matter or nutrients present in the treated wastewater (effluent) that is discharged from a wastewater treatment plant.

STEP 1: Convert Input(s) to Base Unit

Observed Cell Yield: 0.8 --> No Conversion Required
Average Daily Influent Flow Rate: 1.2 Cubic Meter per Day --> 1.38888888888889E-05 Cubic Meter per Second (Check conversion here)
Influent Substrate Concentration: 25 Milligram per Liter --> 0.025 Kilogram per Cubic Meter (Check conversion here)
Effluent Substrate Concentration: 15 Milligram per Liter --> 0.015 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_x = Y_obs*Q_a*(S_o-S)*8.34 --> 0.8*1.38888888888889E-05*(0.025-0.015)*8.34

Evaluating ... ...

P_x = 9.26666666666668E-07

STEP 3: Convert Result to Output's Unit

9.26666666666668E-07 Kilogram per Second -->80064.0000000001 Milligram per Day (Check conversion here)

FINAL ANSWER

80064.0000000001 ≈ 80064 Milligram per Day <-- Net Waste Activated Sludge
