The ozone kit is installed in the existing pool or spa filtration plumbing. There are several basic designs of ozone generators but they all inject the ozone gas into the pool water through a small tube. The concentration of ozone gas is strongest at the point of entry for effective purification. An ozone system is not actually "no-chemicals" because you will still need to keep a very low residual level of chlorine in the pool water. This is generally only about 20 percent as much chlorine as when no ozone is used. The two basic types of ozone generators are ultraviolet (UV) and corona discharge (CD). UV systems use a fluorescent light to create ozone as the sun does above the earth. CD units use an electrical arc inside a generator to create ozone as lightning does (the fresh smell after a storm). Ozone is the most powerful oxidizer that can be used in a pool or spa, but in most cases you will need to supplement with chlorine.
The electrodes are placed close together and the water that is disinfected flows past the electrodes. An electric current is created thus causing the outer atoms of the electrodes to lose an electron and become positively charged. The larger part of the ions flows away through the water, before reaching the opposite electrode. Generally the amount of silver ions at a copper ion rate of 0,15 to 0,40 ppm lies between 5 and 50 ppb. The ion concentration is determined by the water flow. The number of ions that is released increases when electric charges are higher. When copper ions (Cu+) dissolve in water they are oxidized immediately to form Cu2+ ions. Copper can be found in the water in free form. It is commonly known to bond to water particles. Copper (Cu+) ions are unstable in water unless a stabilizing ligand is present. Again, you will need to maintain a modest chlorine residual.
