Sludge Volume Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sludge Volume Index = (Sludge Volume*1000/MLSS)
SVI = (V_ob*1000/X)
This formula uses 3 Variables

Variables Used

Sludge Volume Index - (Measured in Milliliter per Gram) - Sludge Volume Index is the ratio of volume to MLSS.
Sludge Volume - Sludge Volume (mL/L) is represented in terms of milliliter per liter.
MLSS - (Measured in Milligram per Liter) - MLSS is the sum of volatile suspended solids (organics) and fixed suspended solids (inorganics).

STEP 1: Convert Input(s) to Base Unit

Sludge Volume: 2.5 --> No Conversion Required
MLSS: 1200 Milligram per Liter --> 1200 Milligram per Liter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

SVI = (V_ob*1000/X) --> (2.5*1000/1200)

Evaluating ... ...

SVI = 2.08333333333333

STEP 3: Convert Result to Output's Unit

0.00208333333333333 Cubic Meter per Kilogram -->0.00208333333333333 Liter per Gram (Check conversion here)

FINAL ANSWER

0.00208333333333333 ≈ 0.002083 Liter per Gram <-- Sludge Volume Index
