Overall Efficiency of Two Stage Trickling Filter Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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

STEP 1: Convert Input(s) to Base Unit

Influent BOD: 24 Milligram per Liter --> 0.024 Kilogram per Cubic Meter (Check conversion here)
Effluent BOD: 0.4 Milligram per Liter --> 0.0004 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E = (Q_i-Q_o/Q_i)*100 --> (0.024-0.0004/0.024)*100

Evaluating ... ...

E = 0.733333333333333

STEP 3: Convert Result to Output's Unit

0.733333333333333 --> No Conversion Required

FINAL ANSWER

0.733333333333333 ≈ 0.733333 <-- Overall efficiency TF

Efficiency of Second Filter Stage

Go Efficiency of Second Filter Stage = 100/(1+((0.0561/(1-Efficiency of First Filter Stage))*sqrt(BOD Loading to Filter 2/(Volume*Recirculation factor))))

Efficiency of First Filter Stage using Efficiency of Second Filter Stage

Go Efficiency of First Filter Stage = 1+((0.0561/(100/Efficiency of Second Filter Stage)-1)*sqrt(BOD Loading to Filter 2/(Volume*Recirculation factor)))

Efficiency of First Filter Stage

Go Efficiency of First Filter Stage = 100/(1+(0.0561*sqrt(BOD Loading to Filter 2/(Volume*Recirculation factor))))

Efficiency of First Filter Stage given Overall Efficiency

Go Efficiency of First Filter Stage = (Overall efficiency TF-Efficiency of Second Filter Stage)/(1-Efficiency of Second Filter Stage)

Efficiency of Second Filter Stage given Overall Efficiency

Go Efficiency of Second Filter Stage = (Overall efficiency TF-Efficiency of First Filter Stage)/(1-Efficiency of First Filter Stage)

Efficiency of First Filter given BOD Loading for Second Filter

Go Efficiency of First Filter Stage = 1-(BOD5 loading to the second stage filter/BOD Loading to Filter 2)

Overall Efficiency of Two Stage Trickling Filter

Go Overall efficiency TF = (Influent BOD-Effluent BOD/Influent BOD)*100

Overall Efficiency of Two Stage Trickling Filter Formula

Overall efficiency TF = (Influent BOD-Effluent BOD/Influent BOD)*100
E = (Q_i-Q_o/Q_i)*100

What is a 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.

How to Calculate Overall Efficiency of Two Stage Trickling Filter?

Overall Efficiency of Two Stage Trickling Filter calculator uses Overall efficiency TF = (Influent BOD-Effluent BOD/Influent BOD)*100 to calculate the Overall efficiency TF, Overall Efficiency of Two Stage Trickling Filter is the total efficiency obtained after the waste passes from 2 filters. Overall efficiency TF is denoted by E symbol.

How to calculate Overall Efficiency of Two Stage Trickling Filter using this online calculator?
