Sweet sorghum juice is used as sole carbon source for ethanol production by Saccharomyces cerevisiae. The overall in situ sterilisation duration is 40 minutes at 120 0C for a pilot reactor (50 L) which is filled with 60% of working volume. The non-sterile medium consists of 3.28 x 106 contaminants L-1. During the autoclaving process, you have noticed that the time taken for heating and cooling are 18 minutes and 15 minutes, respectively. As a process engineer, explain if you agree with this sterilisation practice by using quantitative analysis.

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 monochloramine Disinfection data in the table below can be used.
