You are treating 10 million gallons per day (MGD) of water with alum at a dosage of 50.0 mg/L. Alum is available as a hydrated salt Al2(SO4)3.16H2O. Determine:(a) The monthly alum dosage required in metric tons/month (1 metric ton = 1000 kg)(b) If you assume that each equivalent of alum added to the water consumes 1 equivalent of alkalinity, determine the alkalinity consumed by alum addition in milliequivalents/L (meq/L)(c) Given that the raw water contained 30 mg/L as CaCO3 of alkalinity, is the alkalinity sufficient? What would happen if the alkalinity is inadequate?

You are the lead engineer on a wastewater treatment plant with a biological reactor. You are required todetermine how much biomass will be produced in kg per day in your plant. A junior engineer determines theultimate BOD of the incoming waste as 600 mg/l, with a decay constant of 0.1/d. The incoming substrateconcentration used should be the five-day BOD. The incoming flow is 75 m3/d however there are lossesupstream of the plant accounting for 15 m3/d of the flow. The target BOD discharged from the plant is 25mg/l. the kinetic constants for the system are Ks = 90 mg/L BOD5, kd = 0.2 d-1, μm = 1.5 d-1, and Y = 0.6 mg VSS/mgBOD5. Include a sketch to illustrate the biological reactor and its incoming flows.
