Copper-silver Ionization

A study published in 2010 by Legionella Pneumophilia specialists Lin, Stout and Yu reavealed that copper-silver ionization was the best method available today to eradicate this bacteria, and many more other pathogens, in sanitary hot water systems.
[ Summary of the study by Lin, Stout and Yu ]Silver has long been known as a bacterial killer and used extensively by medical profession before the introduction of antibiotics. Copper is recognized as one of the best algaecide killers known to man.It was NASA that designed the first ionization system for their Apollo flights, using copper silver electrodes to purify their water. H2O Biotech has improved the technique to kill the bacteria and algae found in institutional, commercial and industrial water systems.H2O Biotech Copper-Silver Ionization Systems work by electrolysis. Electrolysis separates chemically bonded elements in electrodes by passing an electric current through them. The system consists of a control box delivering a low voltage DC current to the electrodes fitted in a reaction chamber.Water flows between the electrodes and picks up electrically charged ions of copper and silver that are released through electrolysis as Cu++ and Ag+. The long-lived and stable Cu++ and Ag+ ions are therefore freely spread out everywhere in the water system.

Since the external membrane of algae and bacteria are negatively charged, they attract the copper and silver ions. Copper and silver are active against a wide range of bacteria, fungi, algae and viruses, including pathogenic organisms, such as Legionella, found as pollutants of surface water systems. The ions penetrate into them and settle on the DNA, thus entailing the total destruction of the cells.

Depending on the complexity of the water network and the length of the standing biofilm contamination, it may take a few days or weeks for ionization to remove all traces of contaminants. However, once this has been achieved, the system will remain free of them indefinitely.

Copper and Silver ions are pH neutral, non-corrosive and have no effect on the human body in the concentration used to treat the water.

UV Ozonation

Ozone is nature’s natural purifier. This naturally occurring product is produced during lightning and electrical storms as well as when solar ultraviolet rays strike the earth’s upper atmosphere. This is the famous Ozone layer which protects us from the harmful UV radiation produced by the sun.Ozone is generated when an oxygen molecule (O2) is exposed to high energy, ultraviolet (UV) light and is converted to an Ozone (O3) molecule. This extra oxygen atom is what makes Ozone a highly “energetic” oxidizer.

Ozone’s effects come when this “extra” oxygen atom is released and allowed to oxidize and destroy bacteria, viruses, as well as other organic matter in the water. Ozone can also break down harmful chemicals and act as a flocculant to coagulate various insoluble particles which can then be easily removed by the filtration system.

Ozone’s powerful oxidizing abilities work in conjunction with your sanitizing agent (chlorine or bromine)* to provide a healthier, cleaner bathing experience. As an oxidizer, Ozone eliminates objectionable chemical by-products such as chloramine or bromamine. The result: an ecological choice, totally environmentally safe.

* In concentration amounts according to local regulations in effect.
