Penn State’s wastewater treatment plant handles 10 MGD. The influent to the primary clarifier has 400 mg/L solids. The primary clarifier does a great job of removing solids, taking out 27%. The sludge flows at a rate of 0.01 MGD. a. What is the solids concentration of the primary clarifiers sludge? B. What total mass of solids (in kg/year) heads to the landfill from the primary clarifier?
