Accurately determine Mixed Liquor Volatile Suspended Solids (MLVSS), a crucial parameter for monitoring and controlling the biological activity in activated sludge wastewater treatment systems. Our free online MLVSS calculator simplifies complex calculations, ensuring optimal plant performance and regulatory compliance. Understand the health of your biomass with ease.

Formula:

MLVSS (mg/L) = [(B - C) / V] × 1000

Where:

  • B = Weight of filter + dried residue (mg)
  • C = Weight of filter + ash (mg)
  • V = Volume of sample (mL)

This formula accurately determines the concentration of active microorganisms (volatile solids) in your mixed liquor sample.
