Sludge Recirculation Ratio given Sludge Volume Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Recirculation Ratio = (Settled Sludge Volume/Mixed Liquor Suspended Solids)*1000
α = (SSV/X^')*1000
This formula uses 3 Variables

Variables Used

Recirculation Ratio - Recirculation Ratio is the ratio of the RAS pumping rate to influent flow rate.
Settled Sludge Volume - (Measured in Kilogram per Cubic Meter) - Settled Sludge Volume is the volume of sludge that has settled out from wastewater during a treatment process, typically in a sedimentation tank or clarifier.
Mixed Liquor Suspended Solids - (Measured in Kilogram per Cubic Meter) - Mixed Liquor Suspended Solids refers to the concentration of suspended solids in the mixed liquor of an aeration tank during the activated sludge process.

STEP 1: Convert Input(s) to Base Unit

Settled Sludge Volume: 1.29 Milligram per Liter --> 0.00129 Kilogram per Cubic Meter (Check conversion here)
Mixed Liquor Suspended Solids: 857 Milligram per Liter --> 0.857 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α = (SSV/X^')*1000 --> (0.00129/0.857)*1000

Evaluating ... ...

α = 1.50525087514586

STEP 3: Convert Result to Output's Unit

1.50525087514586 --> No Conversion Required

FINAL ANSWER

1.50525087514586 ≈ 1.505251 <-- Recirculation Ratio
