Listed below are total solids and suspended-solids data on an industrial wastewater sample. Total solids data Weight of empty dish = 85.337 g Weight of dish plus dry solids = 85.490 g g Weight of dish plus ignited solids = 85.375 g Volume of wastewater sample = 85ml Suspended solids data Weight of glass-fiber filter disk = 0.1400 g Weight of disk plus dry solids = 0.1530 g Weight of disk plus ignited solids = 0.1426 g Volume of wastewater filtered = 200 ml Calculate the total solids (TS), total suspended solids (TSS), total dissolved solids (TDS) (expressed as mg/L). (Note: TS=TSS+TDS) For each of these three solids fractions, calculate the volatile (organic) and fixed (inorganic) fractions, expressed as both mg/L and % of total. (Note: total = volatile+fixed) Summarize your results in the following table.
