Efficiency of First Filter given BOD Loading for Second Filter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Overall Efficiency = 1-(BOD Loading to the Second Stage Filter/BOD Loading to Filter 2)
E = 1-(W_'/W^')
This formula uses 3 Variables

Variables Used

Overall Efficiency - Overall Efficiency refers to the total efficiency of the trickling filter. It is calculated in percentage.
BOD Loading to the Second Stage Filter - (Measured in Kilogram per Day) - BOD Loading to the Second Stage Filter is the total BOD present in the incoming sewage in filter 2.
BOD Loading to Filter 2 - (Measured in Kilogram per Day) - BOD Loading to Filter 2 refers to the total BOD present in the incoming sewage in filter 2.

STEP 1: Convert Input(s) to Base Unit

BOD Loading to the Second Stage Filter: 0.42 Kilogram per Day --> 0.42 Kilogram per Day No Conversion Required
BOD Loading to Filter 2: 2.4 Kilogram per Day --> 2.4 Kilogram per Day No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E = 1-(W_'/W^') --> 1-(0.42/2.4)

Evaluating ... ...

E = 0.825

STEP 3: Convert Result to Output's Unit

0.825 --> No Conversion Required

FINAL ANSWER

0.825 <-- Overall Efficiency

(Calculation completed in 00.004 seconds)

What is Filter Stage?

Filter Stage unit consists of a primary settling tank, filter, secondary settling tank, and facilities for recirculation of the effluent. Two-stage filters consist of two filters in series with a primary settling tank, an intermediate settling tank which may be omitted in certain cases, and a final settling tank.
