Swimming Pool Water Treatment

Ozone in Swimming Pool Treatment

For swimming pool water treatment, addition of ozone to the process complements the existing system of filtration and chemical treatment including chlorine dosing. Pool water gets contaminated due to bacterial load introduced by the bather, atmospheric bacterial activity at the surface and the formation of algae in the presence of sunlight. If this water is not treated properly, the algae will turn the water green and turbid besides giving a boost to microorganisms. This contaminated water can lead to outbreak of diseases. Proper filtration rate supported by a combined disinfection system with ozone and chlorine are required to keep the pool sanitized at all times.

Today, worldwide, swimming pool water is treated with ozone, sometimes reducing the use of chlorine, depending upon the type of pool, ambient conditions, ambient temperature and pool usage. The use of chlorine in pool produces ammonia and halomethanes in reaction with urea mostly from perspiration in water.


These halomethanes are highly carcinogenic in nature. It is these halomethanes and ammonia in water which creates eye and nose irritation along with other side effects like bleaching of hair and other skin problems. Apart from efficient disinfection of pool water, ozone treated pool water looks bluer, very transparent and feels very soft on the skin to the bather free of eye or nose irritation.
