Question
Problem 3
A 2,000 m3 water tower has been taken out of operation to install a chlorine monitor. When the water
tower was put out of operation, its chlorine concentration was 2.0 mg/L. After ten hours, the chlorine
content was determined to be 1.2 mg/L. Considering that the tank is a completely mixed batch reactor and
that there is a first order decay.
a) Calculate the reaction decay rate in day-1.
b) What mass of chlorine (in kg) must be added to the tank to raise the chlorine level back to its
original concentration?
