BOD Loading for Second Stage Filter Solution

STEP 0: Pre-Calculation Summary

Formula Used

BOD Loading to Filter 2 = (1-Efficiency of First Filter Stage BOD Loading)*BOD Loading to Filter
W^' = (1-E_f)*W
This formula uses 3 Variables

Variables Used

BOD Loading to Filter 2 - (Measured in Kilogram per Second) - BOD Loading to Filter 2 refers to the total BOD present in the incoming sewage in filter 2.
Efficiency of First Filter Stage BOD Loading - Efficiency of First Filter Stage BOD Loading calculates the efficiency of the filter at the first stage.
BOD Loading to Filter - (Measured in Kilogram per Second) - BOD Loading to Filter refers to the total BOD present in the incoming sewage.

STEP 1: Convert Input(s) to Base Unit

Efficiency of First Filter Stage BOD Loading: 0.3 --> No Conversion Required
BOD Loading to Filter: 3.5 Kilogram per Day --> 4.05092592592593E-05 Kilogram per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W^' = (1-E_f)*W --> (1-0.3)*4.05092592592593E-05

Evaluating ... ...

W^' = 2.83564814814815E-05

STEP 3: Convert Result to Output's Unit

2.83564814814815E-05 Kilogram per Second -->2.45 Kilogram per Day (Check conversion here)

FINAL ANSWER

2.45 Kilogram per Day <-- BOD Loading to Filter 2

(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.
