Here is how the Mixed Liquor Suspended Solid equation looks like.

1.998 = \frac{3.33 \cdot 0.0009}{0.001 \cdot 1.5}

1.998mg/L = \frac{3.33m³ \cdot 0.0009mg/L}{0.001 \cdot 1.5m³}

1.998 = \frac{3.33 \cdot 0.0009}{0.001 \cdot 1.5}

Mixed Liquor Suspended Solid Solution

Follow our step by step solution on how to calculate Mixed Liquor Suspended Solid?

FIRST Step Consider the formula

X = \frac{Q \cdot Q i}{FM \cdot V}

Next Step Substitute values of Variables

∴

X = \frac{3.33m³ \cdot 0.0009mg/L}{0.001 \cdot 1.5m³}

Next Step Convert Units

∴

X = \frac{3.33m³ \cdot 9E-7kg/m³}{0.001 \cdot 1.5m³}

Next Step Prepare to Evaluate

∴

X = \frac{3.33 \cdot 9E-7}{0.001 \cdot 1.5}

Next Step Evaluate

∴

X = 0.001998kg/m³

LAST Step Convert to Output's Unit

∴

X = 1.998mg/L

Formulas to find Volume of Tank

Other Formulas to find MLSS

Go MLSS given Microbial Mass in Aeration System

X = (\frac{M t}{V})

Go MLSS given BOD Load Applied to Aeration System

X = \frac{M t \cdot Q \cdot Q i}{V \cdot BOD}

Other formulas in Food is to Microorganism Ratio or F is to M Ratio category

Go Food to Microorganism Ratio

FM = \frac{BOD}{M t}

Go Daily BOD Load given Food to Microorganism Ratio

BOD = FM \cdot M t

Go Total Microbial Mass given Food to Microorganism Ratio

M t = \frac{BOD}{FM}

Go BOD Load applied to Aeration System

BOD a = Q \cdot Q i

How to Evaluate Mixed Liquor Suspended Solid?

Mixed Liquor Suspended Solid evaluator uses MLSS = (Sewage Flow*Influent BOD)/(Food to Microorganism Ratio*Volume of Tank) to evaluate the MLSS, The Mixed Liquor Suspended Solid formula is defined as the concentration of suspended solids in the mixed liquor of an aeration tank during the activated sludge process in wastewater treatment. MLSS is denoted by X symbol.

How to evaluate Mixed Liquor Suspended Solid using this online evaluator? To use this online evaluator for Mixed Liquor Suspended Solid, enter Sewage Flow (Q), Influent BOD (Q_i), Food to Microorganism Ratio (FM) & Volume of Tank (V) and hit the calculate button.

FAQs on Mixed Liquor Suspended Solid

What is the formula to find Mixed Liquor Suspended Solid?

The formula of Mixed Liquor Suspended Solid is expressed as MLSS = (Sewage Flow*Influent BOD)/(Food to Microorganism Ratio*Volume of Tank). Here is an example- 333 = (3.33*9E-07)/(0.001*1.5).

How to calculate Mixed Liquor Suspended Solid?

With Sewage Flow (Q), Influent BOD (Q_i), Food to Microorganism Ratio (FM) & Volume of Tank (V) we can find Mixed Liquor Suspended Solid using the formula - MLSS = (Sewage Flow*Influent BOD)/(Food to Microorganism Ratio*Volume of Tank).

What are the other ways to Calculate MLSS?

Here are the different ways to Calculate MLSS-

MLSS=(Total Microbial Mass/Volume of Tank)
MLSS=(Total Microbial Mass*Sewage Flow*Influent BOD)/(Volume of Tank*Daily BOD)

Can the Mixed Liquor Suspended Solid be negative?

No, the Mixed Liquor Suspended Solid, measured in Density cannot be negative.

Which unit is used to measure Mixed Liquor Suspended Solid?

Mixed Liquor Suspended Solid is usually measured using the Milligram per Liter[mg/L] for Density. Kilogram per Cubic Meter[mg/L], Kilogram per Cubic Centimeter[mg/L], Gram per Cubic Meter[mg/L] are the few other units in which Mixed Liquor Suspended Solid can be measured.
