How to Calculate Recirculation Factor given Efficiency of Second Filter Stage?
Recirculation Factor given Efficiency of Second Filter Stage calculator uses Recirculation factor = (BOD Loading to Filter 2/Volume)*1/(((1-Efficiency of First Filter Stage)/0.0561)*(100/Efficiency of Second Filter Stage-1))^2 to calculate the Recirculation factor, Recirculation Factor given Efficiency of Second Filter Stage is the ratio of recirculated flow to the total flow of raw sewage. The capacity of the pumps doing the recirculation of sewage is determined with this. Recirculation factor is denoted by F symbol.
How to calculate Recirculation Factor given Efficiency of Second Filter Stage using this online calculator? To use this online calculator for Recirculation Factor given Efficiency of Second Filter Stage, enter BOD Loading to Filter 2 (W'), Volume (VT), Efficiency of First Filter Stage (E1) & Efficiency of Second Filter Stage (E2) and hit the calculate button. Here is how the Recirculation Factor given Efficiency of Second Filter Stage calculation can be explained with given input values -> 1.4E-7 = (2.77777777777778E-05/0.63)*1/(((1-100)/0.0561)*(100/99-1))^2.
