Chlorine disapears in arsenic removal system
I have a chlorine injection pump flowed by a retention tank flowed by an IE system for Arsenic removal. When I test the total chlorine level out from the tank it is 2 to 3 ppm. When tested after the IE system there is no chlorine.
Can somebody please explain the reaction which removes the chlorine from the IE system. Also is there a way to know how much total chlorine I should have coming out from the tank. The chlorine is used as oxidant for the Arsenic.
