BOD of Influent Entering Filter Solution

STEP 0: Pre-Calculation Summary
Formula Used
Influent BOD = Effluent BOD/exp(-1*Reaction rate constant*Depth*(Hydraulic loading)^(-1*Empirical Constant))
Qi = Qo/exp(-1*Kd*D*(H)^(-1*A0))
This formula uses 1 Functions, 6 Variables
Functions Used
exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)
Variables Used
Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.
Effluent BOD - (Measured in Kilogram per Cubic Meter) - Effluent BOD is the amount of BOD present in the outing sewage.
Reaction rate constant - (Measured in 1 Per Second) - Reaction rate constant quantifies the rate and direction of a chemical reaction.
Depth - (Measured in Meter) - Depth is the distance from the top or surface to the bottom of something.
Hydraulic loading - (Measured in Meter per Second) - Hydraulic loading is define as rate of flow.
Empirical Constant - The Empirical constant is a self determined constant whose value is accessible from table of such constants. This constant is used to calculate the intrinsic carrier concentration.
STEP 1: Convert Input(s) to Base Unit
Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)
Reaction rate constant: 0.05 1 Per Day --> 5.78703703703704E-07 1 Per Second (Check conversion here)
Depth: 3 Meter --> 3 Meter No Conversion Required
Hydraulic loading: 3 Meter per Second --> 3 Meter per Second No Conversion Required
Empirical Constant: 100 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Qi = Qo/exp(-1*Kd*D*(H)^(-1*A0)) --> 0.0004/exp(-1*5.78703703703704E-07*3*(3)^(-1*100))
Evaluating ... ...
Qi = 0.0004
STEP 3: Convert Result to Output's Unit
0.0004 Kilogram per Cubic Meter -->0.4 Milligram per Liter (Check conversion here)
FINAL ANSWER
0.4 Milligram per Liter <-- Influent BOD
(Calculation completed in 00.004 seconds)

6 Eckenfelder Trickling Filter Equation Calculators

Hydraulic Loading Rate given BOD of Influent Entering Filter
Go Hydraulic loading = (ln(Effluent BOD/Influent BOD)/(-1*Depth*Reaction rate constant))^(-1/Empirical Constant)
BOD of Effluent Getting Out of Filter
Go Effluent BOD = Influent BOD*exp(-1*Reaction rate constant*Depth*(Hydraulic loading)^(-1*Empirical Constant))
BOD of Influent Entering Filter
Go Influent BOD = Effluent BOD/exp(-1*Reaction rate constant*Depth*(Hydraulic loading)^(-1*Empirical Constant))
Area given Hydraulic Loading Rate per Unit Area
Go Area = (Volume Discharged/Hydraulic loading)
Discharge given Hydraulic Loading Rate per Unit Area
Go Volume Discharged = Hydraulic loading*Area
Hydraulic Loading Rate given Discharge
Go Hydraulic loading = Discharge/Area

BOD of Influent Entering Filter Formula

Influent BOD = Effluent BOD/exp(-1*Reaction rate constant*Depth*(Hydraulic loading)^(-1*Empirical Constant))
Qi = Qo/exp(-1*Kd*D*(H)^(-1*A0))

What is influent and effluent?

Influent is water that "flows in". This is the raw, untreated wastewater. Effluent means to "flow out". This is the treated wastewater. The picture at right compares influent and effluent.
