BOD5 of Influent Wastewater to Trickling Filter Solution

STEP 0: Pre-Calculation Summary
Formula Used
Influent BOD = ((Effluent BOD)/(exp(-1*Treatability Constant*Depth of actual filter*(Volumetric flow per unit area)^(-1*Empirical Constant))))
Qi = ((Qo)/(exp(-1*K30/25*D2*(Qv)^(-1*a))))
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.
Treatability Constant - Treatability Constant at 30°C and 25 ft filter depth.
Depth of actual filter - (Measured in Meter) - Depth of actual filter is the virtical dimension of the actuall filter.
Volumetric flow per unit area - (Measured in Meter per Second) - Volumetric flow per unit area of filter unit.
Empirical Constant - Empirical Constant influencing empirical relationships supported by confirmatory data irrespective of theoretical basis such as first principles.
STEP 1: Convert Input(s) to Base Unit
Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)
Treatability Constant: 3 --> No Conversion Required
Depth of actual filter: 7.6 Meter --> 7.6 Meter No Conversion Required
Volumetric flow per unit area: 5 Meter per Second --> 5 Meter per Second No Conversion Required
Empirical Constant: 0.55 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Qi = ((Qo)/(exp(-1*K30/25*D2*(Qv)^(-1*a)))) --> ((0.0004)/(exp(-1*3*7.6*(5)^(-1*0.55))))
Evaluating ... ...
Qi = 4.87461641751843
STEP 3: Convert Result to Output's Unit
4.87461641751843 Kilogram per Cubic Meter -->4874.61641751843 Milligram per Liter (Check conversion here)
FINAL ANSWER
4874.61641751843 4874.616 Milligram per Liter <-- Influent BOD
(Calculation completed in 00.004 seconds)
