Before the bubbles burst, the surface of the metal sheet will be isolated from contact with water, thereby reducing the efficiency of water disinfection; (3) After a period of use, the surface of the metal sheet will be covered with scale, which will affect the Ozone generation reduces the efficiency of water disinfection. Over time, the metal sheet cannot be used and needs to be replaced with a new metal sheet.
