The normal dose of chlorine during pre chlorination is 0.1 to 0.5 ppm.
This results in the oxidization of organic matter and reduces the amount of coagulants required in the water.

The normal dose of chlorine during plain chlorination is 0.5-1ppm.
It should be applied when the water is clear and its turbidity does not exceed 30 ppm.

Super chlorination is the application of chlorine beyond the stage of the break point. It is followed by a contact period of 30-60 minutes.

The normal dose of chlorine during post chlorination is 0.1-0.2ppm.
It is used for protection against contamination.

0.1 to 0.2 mg/litre for plain chlorination. So, the correct answer is 0.2.
