Effectiveness
Ozone is the strongest oxidant and disinfectant commercially
available for the treatment of aqueous solutions and
gaseous mixtures.
Although ozone is only partially soluble in water, it
is sufficiently soluble and stable such that its oxidation
or disinfectant properties can be fully utilized.
After ozone oxidizes or disinfects, it decomposes into
oxygen
Ozone reacts with a large variety of organic compounds
resulting in oxygen-containing organic by-products.
Halogenated organic compounds (i.e., containing one
of the halogenic elements: fluorine, chlorine, bromine,
etc.) cannot be produced during ozonation, unless bromide
ions are present. The ability of ozone to produce "free
bromine" by oxidation of bromide ion is an advantage
of ozone in treatment of swimming pools and cooling
towers.
Although ozone is the strongest oxidizing agent commercially
available, it is reasonably safe to handle. The primary
reason is that it cannot be stored and, therefore must
be generated and used on-site.
Although reactions of ozone in its gaseous phase are
significantly slower than in the aqueous phase, ozone
in its gaseous phase is a proven deodorizer for a variety
of odorous materials.
In treating potable water, wastewater, and landfill
leachate, ozone has the proven ability to convert biorefractory
organic materials to biodegradable materials. As a result,
combining ozone oxidation with subsequent biological
treatment can produce water or wastewater with lower
concentrations of problematic organic compounds more
cost-effectively than either process used individually.
Applying ozone to any medium (liquid or gaseous) does
not add other chemicals. |
