BOD Loading for First Stage Filter Solution

STEP 0: Pre-Calculation Summary

Formula Used

BOD Loading to Filter 2 = Influent BOD*Waste water flow*8.34
W^' = Q_i*W*8.34
This formula uses 3 Variables

Variables Used

BOD Loading to Filter 2 - (Measured in Kilogram per Second) - BOD loading to filter 2 is the total BOD present in the incoming sewage in filter 2.
Influent BOD - (Measured in Kilogram per Cubic Meter) - Influent BOD is the total amount of BOD which is present in the incoming sewage.
Waste water flow - (Measured in Cubic Meter per Second) - Waste water flow are generated from domestic, industrial, and commercial uses.

STEP 1: Convert Input(s) to Base Unit

Influent BOD: 11.2 Milligram per Liter --> 0.0112 Kilogram per Cubic Meter (Check conversion here)
Waste water flow: 28 Cubic Meter per Second --> 28 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W^' = Q_i*W*8.34 --> 0.0112*28*8.34

Evaluating ... ...

W^' = 2.615424

STEP 3: Convert Result to Output's Unit

2.615424 Kilogram per Second -->225972.6336 Kilogram per Day (Check conversion here)

FINAL ANSWER

225972.6336 ≈ 225972.6 Kilogram per Day <-- BOD Loading to Filter 2

(Calculation completed in 00.004 seconds)

BOD Loading to Second Filter Stage given Efficiency of Second Filter Stage

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

BOD Loading for First Stage Filter using BOD Loading for Second Filter Stage

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

BOD Loading for Second Stage Filter

Go BOD Loading to Filter 2 = (1-Efficiency of First Filter Stage)*BOD loading to filter

BOD Loading for First Stage Filter

Go BOD Loading to Filter 2 = Influent BOD*Waste water flow*8.34

BOD Loading for First Stage Filter Formula

BOD Loading to Filter 2 = Influent BOD*Waste water flow*8.34
W^' = Q_i*W*8.34

What is filter stage?

Single-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.
