Ozone generators can purify most of the contaminants in the water. Ozone is highly effective and is not carcinogenic. Ozone acts by oxidation and therefore converts to pure oxygen once the purification has taken place. It is a great alternative to other chemical treatments such as chlorine and bromine. Similar to lightning, Ozone generators use the corona discharge principle to utilize the atmospheric oxygen for ozone production. These 700mg generators operate in a watertight housing has a low energy consumption. The kit comes with mounting screws, non return valve and 1.5 metres of cable all manufactured to Australian standards.
