< 12 Efficiency of High Rate Filters Calculators

Initial Efficiency given Final Efficiency after Two Stage Filtration

Go Efficiency of First Filter Stage = (1-(0.0044*sqrt(BOD in effluent/(Volume*Recirculation factor)))/((100/Efficiency of Second Filter Stage)-1))

Final Efficiency after Two Stage Filtration

Go Efficiency of Second Filter Stage = (100/(1+(0.0044/(1-Efficiency of First Filter Stage))*sqrt(BOD in effluent/(Volume*Recirculation factor))))

Recirculation Factor given Volume of Raw Sewage

Go Recirculation factor = (1+(Volume of recirculated sewage/Volume of Raw Sewage))/(1+0.1*(Volume of recirculated sewage/Volume of Raw Sewage))^2

Filter Volume given Volume of Raw Sewage

Go Volumetric Flow Rate = (Total Organic Load*Volume of Raw Sewage)/(Volume of recirculated sewage*Organic loading)

Efficiency of Single Stage High Rate Trickling Filter

Go Efficiency of First Filter Stage = (100/(1+0.0044*sqrt(Total Organic Load/(Volume*Recirculation factor))))

Unit Organic Loading on Filter

Go Organic loading = (Total Organic Load/(Volume*Recirculation factor))

Recirculation Factor given Recirculation ratio

Go Recirculation factor = (1+Recirculation Ratio)/(1+0.1*Recirculation Ratio)^2

Efficiency of Single Stage High Rate Trickling Filter given Unit Organic Loading

Go Efficiency of First Filter Stage = (100/(1+0.0044*sqrt(Organic loading)))

Volume of Recirculated Sewage given Recirculation ratio

Go Volume of recirculated sewage = Recirculation Ratio*Volume of Raw Sewage

Recirculation Ratio given Volume of Raw Sewage

Go Recirculation Ratio = Volume of recirculated sewage/Volume of Raw Sewage

Volume of Raw Sewage given Recirculation ratio

Go Volume of Raw Sewage = Volume of recirculated sewage/Recirculation Ratio

Unit Organic Loading using Efficiency of Filter

Go Organic loading = (((100/Efficiency of First Stage Filter)-1)/0.0044)^2

Volume of Raw Sewage given Recirculation ratio Formula

Volume of Raw Sewage = Volume of recirculated sewage/Recirculation Ratio
I = R/α

What is recirculation ratio ?

Recirculation ratio 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. The increased load on the trickling filters is also determined by this.
