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*X^R)/(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.

STEP 1: Convert Input(s) to Base Unit

Recirculation Ratio: 1.5 --> No Conversion Required
MLSS in Returned or Wasted Sludge: 2000 Milligram per Liter --> 2000 Milligram per Liter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

X = (α*X^R)/(1+α) --> (1.5*2000)/(1+1.5)

Evaluating ... ...

X = 1200

STEP 3: Convert Result to Output's Unit

1.2 Kilogram per Cubic Meter -->1200 Milligram per Liter (Check conversion here)

FINAL ANSWER

1200 Milligram per Liter <-- MLSS

(Calculation completed in 00.004 seconds)
