Volatile suspended solids

Volatile suspended solids (VSS) is an analytical parameter that represents the undissolved organic matter in a water sample. More technically, it is a water quality parameter obtained from the loss on ignition of total suspended solids.^[1] The heating of sample generally takes place in an oven at a temperature of 550 °C^[1] to 600 °C. It represents the amount of volatile matter present in the undissolved solid fraction of the measured solution. VSS is an important parameter in wastewater treatment and characterization.
