The content of ozone in water does affect its bactericidal effect. The following is the general impact of different ozone concentrations on the sterilization effect:

1. Low ozone concentration (0.1-0.5mg/L):

- Can partially kill some microorganisms, but has limited effect on some oxygen-resistant bacteria and viruses.

- It is somewhat effective in eliminating odors in water, but it may take longer and a higher concentration of ozone to completely eliminate odors.

2. Medium concentration of ozone (0.5-1.5mg/L):

- It has good bactericidal effect and can effectively kill a variety of common bacteria, viruses and other microorganisms.

- In drinking water treatment, this concentration range is often used to ensure water disinfection.

3. High concentration ozone (1.5mg/L and above):

- The bactericidal effect is stronger and can destroy microorganisms more quickly and comprehensively.

 Certain industries or specific environments may require higher concentrations of ozone to achieve the desired disinfection effect.

It should be noted that the specific sterilization effect is affected by many factors, including ozone concentration, contact time, water quality, microbial species, etc. Therefore, when using ozone for water treatment or disinfection, it needs to be adjusted and monitored accordingly. specific situation.
