A contaminant is degraded biologically according to a 1st order reaction. A batch reactor experiment indicated that 85% of the contaminant could be degraded in 25.0 minutes a) What percent removal would be achieved in one CSTR with a detention time of 30 minutes? b) What percent removal would be achieved in two CSTRs in series if they had the same volume and a combined detention time of 30 minutes? c) What is the half-life of the contaminant (in minutes)? d) What would be the percent removal in a single PFR with a detention time of 30 minutes? e) The PFR described above has a horizontal velocity = 0.3 ft/s, a width = 10 ft, and a depth = 10 ft. What is the length of the reactor (in feet) and what flow is passing through the reactor (in mgd)?
