Influent BOD given Overall Efficiency of Two-stage Trickling Filter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Influent BOD = (100*Effluent BOD)/(100-Overall efficiency TF)
Q_i = (100*Q_o)/(100-E)
This formula uses 3 Variables

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.
Overall efficiency TF - Overall efficiency TF is the total efficiency of the trickling filter. It is calculated in percentage.

STEP 1: Convert Input(s) to Base Unit

Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)
Overall efficiency TF: 0.9 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_i = (100*Q_o)/(100-E) --> (100*0.0004)/(100-0.9)

Evaluating ... ...

Q_i = 0.000403632694248234

STEP 3: Convert Result to Output's Unit

0.000403632694248234 Kilogram per Cubic Meter -->0.403632694248234 Milligram per Liter (Check conversion here)

FINAL ANSWER

0.403632694248234 ≈ 0.403633 Milligram per Liter <-- Influent BOD

(Calculation completed in 00.004 seconds)

What is trickling filter?

A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media.
