Bacteria, viruses and other pathogens thrive
in the water around us. Because the membranes which protect
these microbes are constructed with carbon-chain molecules,
they are a prime target for the free-radicals produced from
ozone. Ozone attacks the microorganisms like a shotgun, bursting
their membranes and spilling their contents. The destruction
is virtually instant. Ozone annihilates bacteria and viruses
3,000 times faster than chlorine. Ozone has the oxidizing
strength to kill hardened microbes that survive chlorine
assault. Cryptosporidium parvum is one of the more resilient
water-borne pathogens. Studies have shown that after 18 minutes,
Cryptosporidium was still alive in water containing 350,000
ppm of chlorine. 700,000 ppm of chlorine was required to
instantly kill the cysts. The same study proved that only
1 ppm of ozone was effective in instantly killing the same
Water, Rust, Rotten Eggs?
Anyone who has choked down a glass of raw
well water is familiar with the sickening tasted of sulfur.
And those who have scrubbed rusty and blackened stains from
sinks and bathtubs know the frustrations of iron and manganese
problems. These troublesome minerals are found in heavy concentrations
in ground water throughout the United States. They can wreak
havoc on your clothes, your appliances and your health. With
an oxidizing potential 1.52 times greater than chlorine,
ozone is the most powerful oxidizing agent commercially available. When injected into the water, ozone will instantly oxidize
these suspended elements, producing insoluble compounds which
can then be filtered from the water. Millions of dollars
are spent each years replacing fouled water systems due to
iron, manganese and iron bacteria. With ozone, the result
is refreshingly clean and chemical-free water.
but is it safe to drink?
It has become more and more difficult to
create safe water from increasingly contaminated water sources.
As the volume of chemical pollutants in our water and wastewater
increases, the EPA has employed tough regulations in an attempt
to reverse the contamination of U. S. lakes, rivers and aquifers
as well as people. Modern water and wastewater facility operators
are struggling to find a solution as conventional treatment
methods have fallen short of the new standards. With the
enactment of the newest Disinfection Byproducts Rule (DBPR),
that solution has become more difficult to design.
Progressively, more engineers are turning
to ozone as the only viable option. Ozone has proven a successful
weapon in the destruction of toxins such as pesticides, ammonia
and even lethal poisons such as cyanide. A recent study demonstrated
ozone is effective in destroying lethal hepatoxins and neurotoxins
(Rositano, Nicholson, Pieronne, 1998). The study went
on to show that chlorine, at 10 times the concentration of
could only destroy 75% of the neurotoxins. Amazingly, ozone
is more effective than chlorine, yet leaves no toxic residue
in the water. Ozone is helping facilities exceed the EPA
standards for THMs and HAAs.
