0.3 or 0.2 is the correct answer.

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

And for pre-chlorination, it is 0.1.

For plain, chlorination its a right answer.

Thanks all for explaining.

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.

Heera said:   5 years ago
The normal dose of chlorine during post chlorination is 0.1-0.2ppm.

It is used for protection against contamination.

Heera said:   5 years ago
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.
