After chain reaction in water, this product continuously produces subaeric acid and new ecological oxygen, oxidizes and vaporizes pathogens, interferes with DNA and RNA synthesis of pathogens, coagulates and denatures proteins of pathogens, further interferes with the activity of the enzyme system of pathogens, affects its metabolism, increases the permeability of cell membranes, causes the loss of enzymes and nutrients, dissolves and breaks pathogens, and then kills pathogens.
