A treatment system treating 1.0 m3 /s of water includes a filter followed by a  chlorine contact chamber for removal/inactivation of pathogens. The pathogen concentration  going into the filter is 2,500 pathogens/L. The filter is known to remove 2.5 log of pathogens.  The disinfection system is being designed to reduce the pathogen concentration by 95.2%.  Pathogens are inactivated by chlorine via first order kinetics with a reaction rate constant of  4.0/hr. a. What is the concentration of pathogens in the outlet of the chlorination tank? b. What is the volume of the chlorination tank FeCl3•7H2O + 3HCO3- = Fe(OH)3(s) + 3CO2 + 3Cl- + H2O

Question

A treatment system treating 1.0 m3
/s of water includes a filter followed by a 
chlorine contact chamber for removal/inactivation of pathogens. The pathogen concentration 
going into the filter is 2,500 pathogens/L. The filter is known to remove 2.5 log of pathogens. 
The disinfection system is being designed to reduce the pathogen concentration by 95.2%. 
Pathogens are inactivated by chlorine via first order kinetics with a reaction rate constant of 
4.0/hr.
a. What is the concentration of pathogens in the outlet of the chlorination tank?
b. What is the volume of the chlorination tank

FeCl3•7H2O + 3HCO3- = Fe(OH)3(s) + 3CO2 + 3Cl- + H2O
