Answer to Question #202546 in Chemistry for kim

Question

1.   A wastewater treatment plant receives 440 L/s of flow. This wastewater has solids concentration of 192 mg/L. How many pounds of solids enter the plant every day?

Answer 1

Inflow of solids (per second) = 440 x 192 = 84480 mg/s = 84.480 g/s = 0.084 kg/s

Daily inflow of solids = 0.084 x 60 x 60 x 24 = 7299 kg/day

1 kg = 2.2 pounds

Daily inflow of solids = 7299 x 2.2 = 16 058 pounds/day
