A well-mixed 25mL of raw wastewater is used for TS analyses. A well-mixed 50 -mL of raw wastewater is used for suspended solids analyses. Weights (wt.) of evaporating dish with and without the sample either dried, evaporated, or ignited were determined to constant weight according to Standard Methods (APHA et al. 1998). The laboratory results are Tare wt. of evaporating dish =42.2361g Wt. of dish plus residue after evaporation at 105C=42.4986g Wt. of dish plus residue after ignition at 550C=42.4863g Tare wt. of filter plus Gooch crucible =21.5308g Wt. of residue and filter plus crucible after drying at 105C=21.5447g Wt. of residue and filter plus crucible after ignition at 550C=21.5349g Compute the concentrations of total solids, volatile solids, fixed solids, total suspended solids, volatile suspended solids, and fixed suspended solids
