Ozone (O3) is an allotrope of oxygen (O2). It is a kind of light blue gas with special smell. The molecular structure is triangular, the bond angle is 116 °, its density is 1.5 times that of oxygen, and its solubility in water is 10 times that of oxygen. Ozone is a kind of strong oxidant. Its oxidation-reduction potential in water is 2.07V, only secondary fluoride (2.5V), and its oxidation capacity is higher than chlorine (1.36V) and chlorine dioxide (1.5V). It can destroy the cell wall of bacteria, rapidly diffuse into cells, oxidize and decompose glucose oxidase, which is necessary for the oxidation of glucose in bacteria, and can also immediately produce functions with bacteria and viruses, destroy cells and RNA, Decompose macromolecular polymers such as deoxyribonucleic acid (DNA), RNA, protein, lipids and polysaccharides, and destroy the metabolism and reproduction of bacteria. The killing of bacteria by ozone is caused by the rupture of cell membrane. This link is called cell dissipation, because the cytoplasm is crushed in water. Under the condition of dissipation, cells are unlikely to regenerate. It should be pointed out that, unlike hypochlorite disinfectants, the sterilization ability of ozone will not be affected by the change of pH value and ammonia. Its sterilization ability is 600-3000 times greater than chlorine. Its sterilization and disinfection functions are basically instantaneous. When the ozone concentration in water is 0.3-2mg/L, the bacteria can die within 0.5-1 minutes. The dosage of ozone water required to achieve the same sterilization effect (such as killing rate of Escherichia coli up to 99%) is only 0.0048% of chlorine.

Product description
