A 440-MW coal-fired power plant is burning coal that contains 185 ppb of mercury. The coal firing rate is 300,000 lb/hr, and the flue gus flow rate is 1.0 million scfm. The mercuryy standard that must be met is 0.015 lb/GWh of gross energy output. Calculate the overall mercury cap- ture percentage that is required to mect this standard. If the wet scrub- ber can remove 40% of the mercury that comes into it, what removal efliciency is needed for the activated carbon injection/baghouse system?

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.

250 lbs. of contaminated soil containing 0.500 g of a pollutant per kilogram of soil will be treated (remediation) by agitating the soil in a tank containing a suitable liquid phase to transfer the pollutant. Consider a tank holding 500 gal of liquid is built to treat 250 lb of contaminated soil. The pollutant degrades following a first-order kinetic in which 0.50 percent of it is removed per second. Assuming the reactor is operated for 2 hours, what will be: a) The mass of pollutant remaining in the washed soil b) The g/kg of pollutant remaining in the soil and therefore, the percent removal c) The concentration of the pollutant in the liquid phase
