As a public health engieer you have been tasked wiyh designing a plug flow reactor for the disinfection of Giardia lamblia using either free chlorine and monochloramine. The objective is a three log reduction in the concentration of Giardia lamblia. The kinetics of chlorine decay can be described by a first order coefficient of 0.1 d-1.It is also given that the appropriate contact time, t10, equals the hydrualic residence time (HRT or td) of the plug flow reactor. Question: At a temperature of 5oC and a pH of 7.0, what is the volume of the PFR if the flowrate of the water to be disinfected is 1000 L/d for chlorine and monochloramineDisinfection data in the table below can be used.
