Classification of SolidsClassification of SolidsSuspended Solids
Those solids that are non-filtrable with specified filters and are not volatilized at 103 degrees Celsius.
Stuff that will not go through special filtersand will not be lost when heated to dry the filter.

Those solids that are non-filtrable with specified filters and are not volatilized at 103 degrees Celsius.
Dissolved SolidsThose solids which are in solution and are therefore filtrable.
Stuff that DOES get through the filters

The Suspended Solids are removed from a sample by filtration and weighed.
(Gravimetric)
The Solids are ignited at 550°C.
The remaining solids are the Fixed (inorganic) solids.
The loss on ignition is the Volatile (organic) solids.

Calculate the Percent Total Solids and PercentVolatile Solids of a sludge sample given thefollowing data:
Wt. of Dish = 106.52 gramsWt. of Dish and Wet Sludge = 187.16 gramsWt. of Dish and Dry Sludge = 109.46 gramsWt. of Dish and Ash = 107.96 grams
% Total Solids = Wt. of Dry Solids, gWt. of Wet Sludge, g X 100%
= 109.46 g - 106.52 g187.16 g - 106.52 g X 100%
=2.94 g80.64 g X 100%
= 0.036 X 100% = 3.6 %

Calculation:
TDS, mg/L =Wt. of Dry Solids, (gram)Volume of Sample, mL
X 1,000,000
Wt. of Dry Solids = (Wt. Of Dried Residue & Dish) – (Wt. of Dish )
