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
Px = Yobs*Q*(So-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 is 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 is the concentration of BOD that is present in the influent.
Effluent substrate concentration - (Measured in Kilogram per Cubic Meter) - Effluent substrate concentration is the concentration of the BOD present in the effluent.
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
Px = Yobs*Q*(So-S)*8.34 --> 0.8*1.38888888888889E-05*(0.025-0.015)*8.34
Evaluating ... ...
Px = 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
(Calculation completed in 00.020 seconds)
