Problem 1. A wastewater sample is examined for its solid contents. The ionic strength (μ) of wastewater is 0.01. It is known that 30% of total dissolved solids (TDS) is organic. The volumetric settleable solid concentration is determined as 20 mL/L using Imhoff Cone. It is assumed that 40% of total suspended solids (TSS) is equal to dry-settleable solids. The volumetric settleable solids composes of 2% of dried solids and 98% of water. The density of volumetric settleable solid concentration is given as 1020 g/L. Use information given in problem, calculate: a) Total Dissolved Solids (TDS) concentration as mg/L. b) Total Suspended Solids (TSS) concentration as mg/L. c) Total Solids (TS) concentration as mg/L.

Question
Problem 1. A wastewater sample is examined for its solid contents. The ionic strength (μ) of
wastewater is 0.01. It is known that 30% of total dissolved solids (TDS) is organic. The volumetric
settleable solid concentration is determined as 20 mL/L using Imhoff Cone. It is assumed that 40%
of total suspended solids (TSS) is equal to dry-settleable solids. The volumetric settleable solids
composes of 2% of dried solids and 98% of water. The density of volumetric settleable solid
concentration is given as 1020 g/L. Use information given in problem, calculate:
a) Total Dissolved Solids (TDS) concentration as mg/L.
b) Total Suspended Solids (TSS) concentration as mg/L.
c) Total Solids (TS) concentration as mg/L.
