parameter obtained from the
loss on ignition of
total suspended solids.
The heating of sample generally takes place in an oven at a temperature of 550 °C
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.
