Question

A sample that is analyzed for total solids and suspended solids has the following test results. Total Solids (TS) Analysis volume of sample = 150 mL dry crucible mass = 15.2366 grams dry crucible + solid mass after 103 degree centigrade oven = 16.0256 Total Suspended Solids (TSS) Analysis volume of sample= 20 mL dry filter mass= 1.5210 grams dry mas after 103 degree centigrade oven = 1.5660 grams Show that the relationship and calculate the TS, DS and TSS for this sample (report in mg/L) [ 5260, 3010, 2250 mg/L]

Explanation / Answer

Total solids(TS)=(mass of crucible+solids) -(mass of dry crucible)

=16.0256g-15.2366g=0.789g=789mg/0.150L=5260mg/L

Total suspended solids(TSS)=(mass of filter+solids)-(mass of dry filter)

=1.5660-1.5210=0.045g=45mg/0.020L=2250mg/L

TS=TSS+TDS

TDS=TS-TSS=5260mg/L-2250mg/L=3010mg/L
