What should I do if ozone disinfection is not up to standard?

Did you do any other pretreatment in the early stage? Ozone has requirements for SS value of water quality, chroma and turbidity of water. If the water quality is too poor, pretreatment should be done in the early stage to filter out impurities. If pre-filtered, the concentration value is enough and the sterilization time is enough. You can't completely kill coliform bacteria, so is there a problem in choosing your ozone machine brand? In addition, ultraviolet disinfection equipment is recommended for medical wastewater with more coliform bacteria. Ultraviolet disinfection is ideal for killing coliform bacteria. Ultraviolet disinfection can quickly kill bacteria and viruses in a few seconds. Much faster than ozone sterilization. I suggest you think about it.
