Ozone is a triatomic allotrope of oxygen formed by recombination of oxygen atoms. It is a colorless gas with characteristic pungent odor and can easily be detected at low level of 0.05 ppm. It is a very strong oxidant and is over 3000 times more powerful disinfectant than chlorine. It disinfects, oxidizes, deodorizes, and decolourizes .
Improvement in quality of swimming pool water in Mumbai, Kandivali, Dahisar is attained by elimination of chemical content. Swimming pool water pollution is mainly caused by swimmers. The pollutants can be divided into three groups Micro organisms, organics and solid particles.
Each swimmer carries a large number of micro organisms such as bacteria, virus which can cause disease. Organics come from urine, sweat, and saliva which contain ammonia, urea and amino acids. These react with chlorine and form chloramines which irritate the eyes and skin. Solid particles are due to skin flakes, hair and dust.
KEY BENEFITS OF USING OZONE IN SWIMMING POOLS
Bacteria kill rate is up to three thousand times faster
50% stronger oxidizer than chlorine
Reduces traditional chemical use between 60% - 90%
Reduce handling and storage of unsafe chemicals
Reduce constant purchasing of harmful chemicals
No formation of dangerous by-products
Eliminate red, irritated eyes and dry, itchy skin
Eliminate costly replacement of faded swimwear
Remove unpleasant chlorine / chloramines odors
No adverse health or environmental effects
Improvement of the filter and coagulant capacities. This leads to a reduction of coagulant use and less backwashing of the filter is required
DOSAGES
