What does the waterworks use for disinfection now? How much is the charge? Is there a manufacturer of chlorine dioxide disinfectant in Ningbo?

At present, there are many disinfection methods for tap water disinfection:

Liquid chlorine, chlorine gas;

Other chlorine-containing disinfectants (dichloro, trichloro, bleaching powder) have been banned in some areas;

Oxidative disinfectants (chlorine dioxide, ozone, etc.). )

Physical disinfection (ultraviolet rays, etc.). )

At present, liquid chlorine and chlorine dioxide are the most widely used. Liquid chlorine is cheap, but there are many by-products and the cost is below 2 cents. Chlorine dioxide disinfection has no residue, but the cost is slightly higher, generally more than 3 points.

I'm afraid there is no chlorine dioxide manufacturer in Ningbo. I'll tell you one from Shandong.
