This uses in the industry circulating water (central air conditioning,power plant, metallurgy, cooling water, two water supplies and so on)the sterilization extinguishes in the algae treating processes to beable effectively to kill extinguishes each kind of bacteriumvegetative form, the bacterium tooth spore, in each kind of viral aswell as the industry circulating water main harm mold mushroom spawn(for example different oxygen fungus, hard bacterium, sulfate returnto original state fungus and so on). also may effectively oxidize,degrades in the water the pollutant, like C N, S 2-, F E 2+, M N 2+,the phenol and so on causes virulently for non-toxic, cannot have thetradition to disappear the venom chlorine, The sodium hypochlorite andso on produces carcinogen and so on the chloroform in the applicationprocess, also cannot cause two times of pollution, and has thedecontamination, except rank, the decolorization, deodorizes, and soon the unique merit. at the same time this and in the circulatingwater water stabilizer coordination effect is good except the algae,reduces to the equipment and the pipeline corrosion. Welcome everybody to come to discuss.
