OZONE

OZONE VS. UV

 

CES uses ozone in a special device which allows us to oxidize complex chemicals ordinary ozone won't

react with. Unlike UV (Ultra-violet Light) ozone will work in cloudy, dark, oily or colored water. This fact is 

a technical revelation to those who preach the greatness of UV disinfection. The treated water must be 

transparent for UV to work and then it can only penetrate a few centimeters.     

 

WHAT IS OZONE ?

Ozone (O3) or trioxygen is a molecule composed of three (3) oxygen atoms, temporarily existing in a very

unstable and reactive state. Ozone is so reactive that a suitable container for storage probably does not

exist. Unlike the O2 molecule described in the next paragraph, this triatomic oxygen defies man’s attempts

 to store or liquefy it. Compared to O2, O3 is an extremely active molecule, probably by a factor of 1,000

times and is sometimes referred to as activated oxygen. Oxygen (O2) is normally thought of as the fraction

of air which is utilized in breathing. It is very necessary and has many common and obvious uses. This

regular oxygen or dioxygen is a relatively stable molecule, composed of two (2) oxygen atoms held

together with a fairly firm double bond. This diatomic oxygen is stable enough to compress, liquefy

and store, yet it is still quite reactive. Ozone can be visualized as a regular O2 molecule with a very

nervous, active, reactive, excitable, energetic, corrosive and lively O1 atom as a side kick. This monatomic

O1 atom does not like to be alone, and near the earth's surface, it refuses to stay with the fairly stable

O2 double bond. It is active and reactive, with energy needing to be channeled in some useful direction.

It will combine with virtually anything on contact, or at least will try. This active O1 will not stabilize until it

can break away from the O2 and form a stable molecule with something else, virtually any other molecule

that is available. If no other molecule is available, it will eventually unite with another O1 atom in the

same situation, and restabilize as O2.

 

Ozone is a very strong disinfectant and oxidizer. Any pathogen or contaminant that can be disinfected,

altered or removed via an oxidation process will be affected by ozone. It is the strongest of all molecules

available for disinfection in water treatment, and is second only to elemental fluorine in oxidizing power.

Compared to chlorine, the most common water disinfection chemical, ozone is a more than 50% stronger

oxidizer and acts over 3,200 times faster. Both chlorine and fluorine are highly toxic chemicals. On this

planet, ozone is a major work horse. From the highest reaches of the atmosphere to the bottom of the

deepest ocean, ozone is a very efficient protector, provider and recycler. It constantly tries to get rid of

one oxygen atom, O3 O2+O1, which allows it to react with almost anything it encounters. When this single

oxygen atom (O1) forms a tight bond with twin hydrogen atoms, we have water (H2O), without which this

planet would be as barren as the moon. Without water, life as we know it can not exist.

 

If earth had no Ozone layer to protect it by absorbing UV light, life as we know it would not exist. We would

require special skin to keep us being roasted alive.

 

Ozone vs. Chlorine 

Ozone is recognized among the strongest, fastest, commercially-available disinfectants and oxidants for water treatment.

In addition, chlorine can not treat all water-borne pathogens, while ozone can. Cryptosporidium is only one of the many

known but unregulated pathogens that chlorine alone cannot treat (assuming practical, safe doses are used, and

remembering that chlorine is a poison at high doses). Further, chlorine generates trihalomethanes (THMs), which are

disinfection by-products known to be carcinogenic, according to the American Journal of Public Health. THMs,

including chloroform, occur due to a reaction with organics in the water, and are regulated by the USEPA. It was

planned that THMs were to be more stringently regulated; however, budget limitations have prevented the needed

efforts to effect a limit lower than the 100 ppb (parts per billion) USEPA Interim (I) standard now in effect.  An approach

for municipal water treatment, used in many large cities, and public water supplies, is to use ozonation for pretreatment

and a reduced amount of chlorine for post treatment. This method takes advantage of the best of chlorine and ozone

characteristics as reported by the Electric Power Research Institute in 1993. If there is any unused ozone, it reverts

back pure to oxygen. The decreased amount of chlorine used for post treatment provides protection for miles of distribution.

Chlorine residual lasts for a longer time than ozone, and provides a measure of protection for the water. This method of

using ozone for pretreatment in a public water supply decreases the amount of chlorine used in comparison to traditional

chlorination, all while providing a quality product water. The decreased amount of chlorine used results in reduced THMs

and other disinfection byproducts that are caused by chlorination. The reduction in chlorine also has the benefit of reducing

or eliminating the taste and odor complaints municipalities receive. Conventional full strength chlorination in municipalities

is well-known for chlorine taste and odor problems.
