A- An industrial wastewater stream flows at a rate of 13500 m³/d containing 100 mg/L. Suspended solids, ferric sulfate [Fe(SO4)] is used as a coagulant' at a dose of 50 mg/L. a) Assuming that there is very little in water, what is the daily lime dose? b) If the sedimentation tank removes 90% of the inlet solids, what is the daily solids production from the sedimentation tank?
Enter T next to the following true statements and F next to the false statements. Settling of suspended solids in secondary clarifiers is typical of Type II sedimentation. Thickening prior to digestion is common in many wastewater treatment plants because it reduces the size needed for the digester. Based on a temperature of 30°C, a design mean cell residenee time of about 20 days would be reasonable for a completely-mixed anaerobic digester without recycle. A volatile suspended solid is defined as an organic solid that can be oxidized to CO2 (g) at 250°C. The theoretical yield coefficient can be estimated from the observed yield coefficient if the specific growth rate constant is known. Air flotation would likely be more efficient for thickening waste activated sludge than primary sludge, while the opposite would be true for gravity thickening. The net mass of cells produced in the activated sludge process equals the total cell mass synthesized minus the cell mass wasted as waste…
