Water Purification O³
Ozone is a very active form of oxygen. It is formed when oxygen is exposed to a high-energy field causing some oxygen molecules (O²) to break down to oxygen atoms (O) The oxygen atoms (O) then react with the oxygen molecules (O²) to form ozone (O³). Notice that this is a reversible reaction meaning that ozone can decompose back to oxygen. The very reactive nature of ozone makes it the ideal oxidant for air and water treatment. Ozone will:

· destroy bacteria and viruses
· precipitate heavy metals (example iron and manganese) allowing them to be filtered
· eliminate colour from water (for example, like the yellowish colour caused by tannin)
· remove rotten egg smell from water (caused by hydrogen sulphide)
· oxidise organic compounds to form compounds that can be easily flocculated and filtered or to form water (H²O) and carbon dioxide (CO²)

Applications include pool & spa treatment, drinking water treatment, irrigation water treatment……more……
