OZONIFICATION IN WATER TREATMENT

Ozonification in Water Treatment Report
Ozone is nature's agent for cleaning and treating both air and water. That clean fresh
smell in the air following a thunderstorm, the bright sky and brilliant colors of nature
are due to ozone - created by lightning and the Sun's energy. Ozone is a gas that is
created naturally in our atmosphere when oxygen in the air is exposed to high intensity
ultraviolet rays. Both the sun and lightning create the ozone. Ozone is also one of
nature's best bleaching agents, restoring discolored water to its naturally clear state.
As an oxidizer and microflocculant, it also helps reduce unwanted organic material form
water, such as iron, manganese, hydrogen sulfide, tannin, and algae. Ozone has been the
preferred treatment in Europe since 1904 for drinking water. Today, there are over 2500
cities world wide relying on ozone for their water treatment. Ozone dissolves in water
ten times faster than pure oxygen and has a half-life of approximately twenty minutes
(when dissolved in water) before it reverts back to oxygen. As ozone oxidizes and treats,
it loses its highly unstable third oxygen atom. Ozone does six things during water
treatment. First ozone reduces iron, manganese, hydrogen sulfide, and various other
minerals from water by oxidation and microfloculation. Second, ozone reduces algae,
fungus, yeast, and mold from the water. Third, ozone oxidizes oils and precipitates some,
but not all, heavy metals. Fourth, ozone increases the dissolved oxygen content of the
water. Fifth, ozone reduces color and odors in water. Sixth, ozone reduces stains on
clothing, bathtubs, toilets, showers and sinks.
