Efficiency of First Filter Stage Solution

STEP 0: Pre-Calculation Summary
Formula Used
Efficiency of First Filter Stage = 100/(1+(0.0561*sqrt(BOD Loading to Filter 2/(Volume*Recirculation Factor))))
E1 = 100/(1+(0.0561*sqrt(W'/(VT*F))))
This formula uses 1 Functions, 4 Variables
Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Efficiency of First Filter Stage - Efficiency of First Filter Stage refers to the efficiency of the filter at the first stage.
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.
Volume - (Measured in Cubic Meter) - Volume is the amount of space that a substance or object occupies or that is enclosed within a container.
Recirculation Factor - Recirculation Factor refers to the average number of passes of the influent organic matter through the trickling filter.
STEP 1: Convert Input(s) to Base Unit
BOD Loading to Filter 2: 2.4 Kilogram per Day --> 2.77777777777778E-05 Kilogram per Second (Check conversion ​here)
Volume: 0.0035 Cubic Meter --> 0.0035 Cubic Meter No Conversion Required
Recirculation Factor: 0.4 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
E1 = 100/(1+(0.0561*sqrt(W'/(VT*F)))) --> 100/(1+(0.0561*sqrt(2.77777777777778E-05/(0.0035*0.4))))
Evaluating ... ...
E1 = 99.2159762780332
STEP 3: Convert Result to Output's Unit
99.2159762780332 --> No Conversion Required
FINAL ANSWER
99.2159762780332 99.21598 <-- Efficiency of First Filter Stage
(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.
