At this time, pre-chlorination is simply used in plants where THM formation will not be a challenge.
It doesn’t destroy all like cyst or parasites. So normally it’s combined with filtration. So, usually there’s chlorination, chlorine is injected and you have a particular volume of Make contact with time Then you definately received filtration. That’s the best way to use it.
