Ozone is a gas - triatomic form of oxygen. It most powerful oxidizing agent available for conventional
water treatment. It is highly reactive and unstable – therefore it must be generated and used on-site.
The weak bond holding ozone's third oxygen atom is what causes the molecule to be unstable and thus,
very effective as an oxidizer. Ozone is only partially soluble in water, but more so than oxygen. The best
property of ozone is that after all its actions it ultimately reverts to environmentally friendly oxygen.
