1. Industrial representatives claim that the NAAQS for S02 is so low that one exceeds it if one strikes a simple woodenmatch in a modest-sized room. Is this true?(a) Calculate the concentration (in µg/m3) expected for striking such a match in a room that is 15 ft by 15 ft by 8 ft. A typical2-inch wooden match contains ≃ 2.5 mg of sulfur.
Poorly treated municipal wastewater is continuously discharged directly into a lake. The discharge from the wastewater plant into the lake occurs at a flow of Qd = 1 m3/hr. The concentration of phosphate (PO43, M = 95 g/mol) in the discharge flow (Cxd) that is decaying with first-order kinetics is 100 mg/L. The lake is a well-mixed water body of 100 m3. (Phosphate is naturally uptaken by algae with a first- order decay rate constant equal to 0.20/day.) The concentration of phosphate in the incoming river (Cx,r) is 10 mg P/L.

Wastewater is treated with an activated sludge plug flow reactor, similar to one seen at the Norman Water Reclamation Facility. The BOD5 after primary treatment is 100mg/L and the effluent limit is 5 mg/L BOD5. Use 1.00 h-1 as the maximum specific growth rate constant and typical values for the other biokinetic constants. The biomass concentration in the reactor is 2,500 mg/L MLSS based on a recycle ratio of 1. Calculate the mean cell residence time, in hours for this system

(4) [Text-problem 4.29] A 90-m³ basement in a residence is found to be contaminated with radon coming from the ground through the floor drains. The concentration of radon in the room is 1.5 Bq L- (becquerels per liter) under steady-state conditions. The room behaves as a CMFR, and the decay of radon is a first-order reaction with a decay rate con- stant of 2.09 × 10-6 s-1. If the source of radon is closed off and the room is vented with radon-free air at a rate of 0.14 m³ s-1, how long will it take to lower the radon concentration to an acceptable level of 0.15 Bq L-¹?
