Problem:
A cfstr is to be used to disinfect water with 5,000 MPN/L of total coli forms. The flow is 200 M3/hr and the first order reaction rate constant is 6/hr.
Required:
Question 1: What volume CFSTR is needed to reduce the bacteria to 10 MPN/L (Standard for drinking water is 1 MPN/100 ml)?
Question 2: If a plug flow reactor is used to disinfect the water, what volume will it be?
Question 3: If a batch reactor is used to disinfect water what will the reaction time be?
