MLSS given Sludge Recirculation Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
MLSS = (Recirculation Ratio*MLSS in returned or wasted sludge)/(1+Recirculation Ratio)
X = (α*XR)/(1+α)
This formula uses 3 Variables
Variables Used
MLSS - (Measured in Milligram per Liter) - MLSS is the sum of volatile suspended solids (organics) and fixed suspended solids (inorganics).
Recirculation Ratio - Recirculation Ratio is the ratio of the RAS pumping rate to influent flow rate.
MLSS in returned or wasted sludge - (Measured in Milligram per Liter) - MLSS in returned or wasted sludge is the mixed liquor suspended solids in returned sludge in terms of mg per litre.
STEP 1: Convert Input(s) to Base Unit
Recirculation Ratio: 1.5 --> No Conversion Required
MLSS in returned or wasted sludge: 2 Milligram per Liter --> 2 Milligram per Liter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
X = (α*XR)/(1+α) --> (1.5*2)/(1+1.5)
Evaluating ... ...
X = 1.2
STEP 3: Convert Result to Output's Unit
0.0012 Kilogram per Cubic Meter -->1.2 Milligram per Liter (Check conversion here)
FINAL ANSWER
1.2 Milligram per Liter <-- MLSS
(Calculation completed in 00.004 seconds)
