Swimming pool /SPA water treatment

August 31, 2010 Leave a comment
Now, ozone  technology is more and more popular for swimming pool or SPA water treatment for its green and safe.
At pools and SPA,  Ozone Cleaning System is used,  in which water is treated with ozone to obtain clear, chemical free, odourless water. Unlike chlorine, ozone treated water don’t have any harmful effect on hair, skin and eyes.

Ozone is one of the strongest commercially available oxidising agents, and is commonly used for the treatment of water in municipal and industrial applications. The special advantage of ozone is in the environmentally friendly way in which it works. Harmful substances, colours, odours and microorganisms are destroyed directly by oxidation, without the formation of harmful chlorinated by-products.

Ozone is a natural, gaseous molecule and is frequently found in nature. As the ozone layer it protects our planet against ultraviolet solar radiation, and can even be formed in low concentrations by lightening bolts or on hot summer days. The fact that ozone is frequently talked about in connection with air pollution, gives the gas a rather negative image – wrongly!  Applied correctly, it is ideally used suitable as an effective and environmentally friendly alternative to oxidation with chlorine, adsorption (e.g. activated carbon) or separation (e.g. reverse osmosis).

The oxidative effect of ozone

Ozone consists of three oxygen atoms. Under normal near-earth conditions the gas is unstable and thus very reactive. The ozone molecule reacts quickly with a number of organic and inorganic compounds, either through directly acting on the ozone molecule or indirectly through hydroxyl radicals that are created. Ozone is usually used up completely by this oxidation process and breaks back down into oxygen. Any remaining ozone in the off-gas is converted back to oxygen by a residual ozone destructor.
