(a) In a wastewater treatment plant, wastewater samples were collected at the headworks. The following water tests were performed using a sample size of 100 ml. The samples used in the solids analysis were all either evaporated or dried to a constant weight Tare mass of evaporating dish = 62.371 g Mass of evaporating dish plus residue after evaporation at 105 °C = 62.453 g Mass of evaporating dish plus residue after ignition at 550 °C = 62.419 g Tare mass of Whatman GFIC filter after drying at 105 °C = 1.636 g Mass of Whatman GF/C filter and residue after drying at 105 °C = 1.652 g Mass of Whatman GF/C filter and residue after ignition at 550 °C = 1.641 g Determine the concentrations of: (i) total solids, (ii) total volatile solids, (ii) total suspended solids, (iv) Volatile suspended solids, (v) total dissolved solid.
