SM 2540D

Total Suspended Solids Dried at 103-105o

Applicability: SM 2540 D which is a method for determining Total Suspended Solids (TSS) in water and wastewater samples. The method involves filtering a known volume of a well-mixed sample through a pre-weighed filter, drying the filter and residue at 103-105°C, and then reweighing it. The increase in weight represents the TSS.

Purpose: The method is used to quantify the amount of solid material that is suspended in a water sample and can be removed by filtration.
