The following data were obtained from a serial filtration test of a settled effluent after biological treatment. Prepare a plot of one of the samples. How great an error in the measurement of the total suspended and colloidal solids would occur if a filter paper with a nominal pore size of 1.2 micrometer was used to determine the total suspended solids, as compared to using a filter with a nominal pore size of 0.1 micrometer?

Suspended solids, mg/IL Saple number Nominal pore size, 2 29.4 11.5 3.5 5.1 13.5 15.1 4 25.1 15.1 2.2 8.9 25.0 17.5 20.2 8.8 22.5 8.0 7.5 15.1 9.9 11.6 21.2 24.9 0.1

Solution

As per interpolation formula method

If filter paper with a nominal pore size of 1.2 micrometer is used to determine the total suspended solids then,

sample-1 = 14.594

sample-2 = 12.94

sample-3 = 20.56

sample-4 = 15.02
