Average Daily Influent Flow Rate given Net Waste Activated Sludge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Average daily influent flow rate = Net waste activated sludge/(8.34*Observed Cell Yield*(Influent Substrate Concentration-Effluent substrate concentration))
Q = P_x/(8.34*Y_obs*(S_o-S))
This formula uses 5 Variables

Variables Used

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.
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.
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

Net waste activated sludge: 20 Milligram per Day --> 2.31481481481481E-10 Kilogram per Second (Check conversion here)
Observed Cell Yield: 0.8 --> No Conversion Required
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

Q = P_x/(8.34*Y_obs*(S_o-S)) --> 2.31481481481481E-10/(8.34*0.8*(0.025-0.015))

Evaluating ... ...

Q = 3.4694466648903E-09

STEP 3: Convert Result to Output's Unit

3.4694466648903E-09 Cubic Meter per Second -->0.000299760191846522 Cubic Meter per Day (Check conversion here)

FINAL ANSWER

0.000299760191846522 ≈ 0.0003 Cubic Meter per Day <-- Average daily influent flow rate
