You Have Four ways to disinfect water

1- using of Ozone

2- using of Hydrogen peroxide

3- UV

4- Filteration using Filter with pores 0.45 microns (Bacterial filter)

Or you can use the following (I recommend that)

1-chlorine injection

2- Carbon filter to remove the Chlorine, smell, taste 

3- Micron Filter

4- UV lamp

5- Ozone

Then after you fill the bottles or containers with ozonated water leave it for 8 hours to make sure Ozone turns to oxygen and become not harmful
