A tray tower provides 10 equilibrium stages for stripping ammonia from a wastewater stream by
using a countercurrent air stream at 1 atm and 300 K. Assume that the inlet water concentration
is 0.2 mole% ammonia, the inlet air does not have ammonia, and 1 SCM (standard cubic meter)
of air is fed to the tower per kilogram of wastewater. Here the equilibrium curve is linear with
m= 1.414.
(a) Estimate the outlet molar concentration in the exit water.
(b) Assuming that the Murphree efficiency for the process is 65%, estimate the number of
real trays required for this process.
(c) How many real trays would be required to achieve ½ of the concentration in (a)?

A wastewater plant needs to reduce the methane content in water in a stripping tower to 0.3 mol %. The liquid stream is entering the tower with a flow rate of 200 mole/h and contains 0.8 mol % methane. The tower uses pure air for stripping and its temperature and pressure are held constant at 300 K and 1 atm, respectively. The equilibrium relation for methane in the air-water system is ? = 1.2?. a) Find the minimum vapor flow...

An environmental activist research group collects 16 samples from a wastewater effluent stream of a chemical plant in Bhopal (India) and measures the concentration of a potent cyanide-based toxin. Their results yield a mean concentration of ?. ? ?pm with a sample variance of ?. ?5 ???^?. It may be assumed that the data are the realization of a normally distributed random variable. (a) What is the two-sided 98% confidence interval for the measured toxin concentration in the effluent stream?...

An aerobic, continuous-strirred-tank-reactor system is used to oxidize formaldehyde in a wastewater stream from a particle board manufacturing facility. The initial formaldehyde concentration is 50 mg/L, the degradation rate constant is 0.18/day, the flow rate is 400 gal/min, and the reactor volume is 12,000 gal. Determine (a) the concentration of formaldehyde in the treated effluent and (b) the amount of oxygen required (lb/d) to carry out the process.

Question 610 pts A BOD test is run using 10 mL of treated wastewater. Chemicals to inhibit nitrification were added. The initial dissolved oxygen (DO) in the bottle is 9.5 mg/L and after 5 days, the DO is 5.0 mg/L. For the bottles that were allowed to run for 20 days, the DO is 4.0 mg/L. A similar test was done where nitrification was not inhibited. The initial DO was the same and the DO after 20 days was 3.0...
