One more reason to use ozone on your pool....
A new study recently hit the press with alarming headlines such as, “Peeing in The Pool May Cause Heart, Lung Problems,”; “Urinating in the Swimming Pool Could Result in a Deadly Chemical Weapon”; and “Some People Pee in the Pool — and It’s Hurting Our Health.” The authors said the experiments showed uric acid, when combined with chlorine, efficiently contribute to the formation of cyanogen chloride (CNCl) and trichloramine (NCl3), the nitrogen-containing byproducts that can have negative health effects when inhaled. NCL3 has been linked to lung injury, while CNCl is toxic and can affect organs such as the lungs, heart and central nervous system. The authors also said the addition of uric acid to chlorine may be a significant contributor to the formation of CNCl in pools. Read the full article from Pool and Spa News
Ideally no one, not even competitive swimmers, would pee in the pool. However, pool owners and recreational facilities can prevent the occurrence of chemical by-products by adding an Ozone or AOP system. Whether from interacting with urine, sweat, or other biologicals in water, chemicals do leave behind by-products. These chemical by-products, not the chemical itself, are the actual culprit of water complaints such as odor, red eyes, itchy skin, discolored hair, and swimsuit fading.
Ozone interacts with chemical by-products and completely removes them from water. Chlorine is recycled back to it's free form, so it can continue to work as a residual sanitizer. Additionally, Ozone/AOP eliminates biologicals and other impurities from water as it flows through the return system so that water is sparkling clean and clear. Chlorine usage can be reduced up to 70%, further eliminating the threat of harmful by-products, saving money on chemicals, and reducing maintenance of balancing water chemistry.

Tech speak: Advanced Oxidation Processing
Ozone and ultraviolet sanitation both have their pros and cons - but new technologies combine both for superior results
Pristine, sanitized, non-toxic water is the goal of all recreational water owners and operators. However, not all chemical sanitation and oxidation treatments are created equal.
The challenges of eliminating toxic chemicals and their byproducts while maintaining water sanitation and oxidation have led consumers and health officials to search for chemical-limited (or reduced chemical) solutions to water treatment. Unfortunately, this search has opened the door to highly promoted "alternative sanitizers," some of which are less effective than others.
This has inspired some manufacturers to develop Advanced Oxidation Processing (AOP) solutions. AOP devices produce hydroxyl radicals (OH-), which constitute a highly potent oxidizer. Hydroxyl radicals are created when ozone is used in conjunction with intense ultraviolet (UV) light and water. To produce hydroxyl radicals, ozone is injected into water that is irradiated by VUV light, or water vapor within a VUV ozone generator.
Ozone and UV
Ozone systems oxidize contaminants such as E. coli, Legionella, and most bacteria and viruses very rapidly. Yet some of the most toxic contaminants can be difficult to destroy, even with ozone. A high ozone concentration is necessary for the more resistant strains of Cryptosporidium, for example - this parasite calls for an ozone generator package geared toward large commercial pools and water features.
Meanwhile, ultraviolet sterilizers have been widely used in the water industry for decades. The method destroys dangerous organisms' DNA, preventing their reproduction. Though UVC is often touted as having the capacity to convert chloramines to free chlorine, only high pressure UVB lamps have been shown to possess that capability.
However, by combining the two technologies of ozone generation and low pressure UVC (a wavelength found in germicidal lamps), the Advanced Oxidation Process has emerged as a new solution for oxidizing and sanitizing hard-to-remove contaminants, such as Cryptosporidium's cystic form, compound chloramines and pharmaceutical residuals.
What is AOP?
AOP is the conversion of ozone by ultraviolet rays on the UVC wavelength, in the presence of water, to form high-energy hydroxyl radicals.
Hydroxyls function in a manner similar to hydrogen peroxide, which is increasingly common for use as an oxidation shock in pools. However, the hydroxyl radical energy level generated in the AOP process is higher than that generated by hydrogen peroxide alone.
When ozone and AOP are mixed into the stream of water, they oxidize many resistant chemicals, which are known as Advanced Toxic Contaminants (ATCs). These include free organisms such as Cryptosporidium, Giardia and Legionella; pharmaceuticals, herbicides and insecticides; and cleaning byproducts such as chloramines.
AOP also produces a short-term active residual, as well as a long-acting hydrogen peroxide residual that will continue to sanitize and provide a measurably increased ORP
How is AOP produced?
There are two major methods for producing AOP, both of which are applicable to swimming pool and spa water.
The first method is to produce ozone with an ozone generator - of either the vacuum-ultraviolet (VUV) or corona discharge (CD) type - and mix that ozone with a stream of water. This ozonated water is then exposed to germicidal UVC downstream. This combination of ozone, UVC and water generates hydroxyl radicals, which are used up rapidly due to their high reaction rate.
The second method uses a VUV ozone generator to both create ozone and generate hydroxyl radicals. In this method, two dominant UV wavelengths - the 185 nm (VUV) ozone-producing frequency and the 254 nm (UVC) germicidal frequency - are generated from the mercury arc.
VUV systems that generate both ozone and hydroxyls are common in the pool and spa industry. In these systems, the VUV within the generator converts oxygen to ozone. This ozone is then exposed to the germicidal UVC, and to water vapor, to produce hydroxyl radicals and hydrogen peroxide.
In 2006, a third AOP design was developed - this hybrid design controls the lamp contamination variables, and also adds enhanced generation of both ozone and hydroxyl formation. The ozone generator contains both ozone producing VUV and germicidal UVC, plus high voltage electrical fields produced by a high-frequency power supply, and rectifiers to accelerate the AOP process.
AOP Advantages
These designs offer certain advantages over traditional corona discharge or ultraviolet systems. Aside from the mechanical benefits of typical VUV ozone generators - such as simplicity, long life and effective biological destruction - they also offer a number of unique attributes. Chief among these is the fact that AOP systems produce a gaseous form of hydroxyl radicals for both air and water, which generate potent chemical reactions that can effectively destroy contaminants.
The logistical advantages are also significant: AOP can be quickly added to existing circulation systems, adding these capabilities without significant increases in cost or complexity over a traditional ozone system. In addition, AOP meets current and proposed health standards, because it is used as an oxidizer as an adjunct to existing sanitation systems.
For all these reasons, AOP may be an ideal solution for larger pools that must deal with contaminant concerns - particularly in areas where state or municipal laws require quick and effective treatment of these issues. If a traditional ozone or UV system isn't meeting all the pool's needs, it could be time to look into the more powerful sanitization AOP can provide.

PROZONE WATER PRODUCTS INVITES RECREATIONAL WATER INDUSTRY TO PARTNER FOR LIVING WATERS FOR THE WORLD
According to the World Health Organization, 3.4 million people die each
year due to lack of access to clean drinking water. Thankfully, organizations like Living Waters
for the World are working to reduce the number.
Prozone Water Products has contributed more than $100,000 towards the
installation of more than 800 water purification systems by Living Waters teams
since 2004. With the help of other
manufacturers in the water industry, they hope to continue expanding the
efforts and saving lives.
Most of the 780 million people who lack access to clean
water are in developing countries and much of Living Water's work is in South
and Central America. There are also teams currently active in the Appalachia
region of the US, primarily in Eastern Tennessee and Kentucky. As of January 1,
2012, over 60 clean water systems were installed in 6 communities in the United States of
America.
Prozone CEO, Ron Barnes, realized even before he founded his
company that the ozone generator he invented could provide a clean water
solution for third world countries because it was relatively inexpensive,
reliable with low maintenance, and would run on low power. Before becoming a physicist, he'd considered
seminary. Years later, partnering with
Living Waters presented an opportunity to live out his desires to help the
world's least fortunate by sharing the technology he'd had the God-given talent
to invent.
Prozone provides UV,
ozone, and Advanced Oxidation systems that purify water on site with easy
installation, little maintenance, and complete sanitation. The EPA certified
technology produces no harmful byproducts or other environmental concerns for
communities. "With the partnership
of other manufacturers and suppliers in the water industry, we can
exponentially influence the effectiveness of general donations by providing
required hardware at reduced or no cost.
Our specific need right now is for a pump manufacturer and a filter manufacturer
to join our team," says Barnes.
Living Waters trains operating partners (local, in-country partners responsible for the
sustainability of the program) to construct a clean water system on site and
lead ongoing health, hygiene & spiritual education. Initiating partners
(typically U.S.-based partners) teach, coach, and ultimately empower operating
partners.
Living Waters for the World's Campaign for Clean Water
program allows businesses to directly help fund specific projects. A $7500 donation delivers a water system
serving a community of 200 to 2000, local leaders trained and empowered to
operate and maintain water system and lead health education, and funds to
ensure long-term system sustainability.
A funding partner representative is invited to accompany the team on an
installation/education trip. With
Campaign for Clean Water, you aren't just making a donation, but also directly
involved in a specific project where you can see the impact of your gift.
