1. Ozone can oxidize the decomposition of bacteria within the bacteria enzymes, so that bacteria inactivated death.
2. Directly with bacteria, viruses, destruction of their organelles and DNA, RNA, so that the metabolism of bacteria is destroyed, leading to bacterial death.
3. Through the cell membrane tissue, invasive cells, the role of the outer membrane of the lipoprotein and the internal lipopolysaccharide, so that the occurrence of permeability loss of bacteria and dissolved.
