CEEB 221: INTRODUCTIONS TO ENVIRONMENTAL ENGINEERINGLABORATORY
EXPERIMENT 2.0: SOLIDS IN WATER AND WASTEWATER
2.1 Objective
To determine the concentration of suspended solids in the sample
2.2 Theory
Total Suspended Solids are solid materials, including organic and inorganic that are suspended in
the water. This would include silt, plankton and industrial waste.Volatile Suspended Solids are
those solids lost on ignition (heating to 550˚c).Fixed Suspended Solids are those solids that
stayed after ignition (heating to 550˚c).
2.3 Procedure
1. A GF/c (glass fiber grade c) filter paper was weighed up to 4 decimal points. (m1)
2. The filter paper was transferred on to a filtration system and 10ml of sample was poured
out.
3. Then the filter paper with the filtered sample was transferred in to the oven and was
heated 100˚c for 1 hour.
4. After 1 hour the filter paper was transferred on the tripod for cooling and then was
weighed. (m2)
5. The filter paper was placed in a 550˚c furnace for 5 minutes and then was transferred
again on the tripod for cooling.

6. The filter paper was weighed. (m3)
2.4 Results (Data Observations)
Data
Volume of sample, ml = 10ml
Mass of filter paper, g = 0.2060 g (m1)
Mass of filter paper + dried solids, g = 0.2210 g (m2)
Mass of filter paper + ignited solids, g = 0.2154 g (m3)
Total Suspended Solid, mg/l = 150 mg/l
Volatile Suspended Solid, mg/l = 56 mg/l
Fixed Suspended Solid, mg/l = 94 mg/l
Calculation
Total Suspended Solid in mg/l = [ (m2 – m1) ÷ sample ] x 105
= [ (0.2210 – 0.2060) ÷ 10 ] x 105
= 150 mg/l
Volatile Suspended Solid in mg/l = [ (m2 – m3) ÷ sample ] x 105
= [ (0.2154 – 0.2060) ÷ 10 ] x 105
= 56 mg/l
Fixed Suspended Solid in mg/l = [ (m3 – m1) ÷ sample ] x 105
= [ (0.2154 – 0.2060) ÷ 10 ] x 105
= 94 mg/l

2.5 Discussion
The mass of the glass fiber grade c filter paper, mass of filter paper + dried solid and mass of
filter paper + ignited solid are taken until 4 decimal points to get the accurate value of
masses. Thus the values are essential to find the Total Suspended Solid, Total Fixed
Suspended Solid and Total Volatile Suspended Solid.The test must be undertaken with
caution because we dealing with high temperature furnace, and oven which all of that can
cause harms. Always wear a thick glove when dealing with the furnace and use clamp to hold
the filter paper.
2.6 Conclusion
From the result we can conclude that the Total Suspended Solid concentration is equal
with Total Fixed Suspended Solid plus Total Volatile Suspended Solid concentration.
