Swimming Pool Water disinfection is one of the key treatment steps for all types of public and private pools. Assured and Efficient pool water disinfection is essential. Swimming pool water is mainly
contaminated by swimmers and also by incoming water quality and environment pollutants
The pollution mainly caused by swimmers makes it a very dynamic pollutant, which is dependent on the number and types of swimmers. Swimming pool pollutants can be divided up into three groups: Micro-organisms (such as bacteria, fungi and viruses), Undissolved pollutants (visible floating particles such as hair, skin flakes, colloidal particles, soap remains etc.,) and dissolved pollutants such as urine, sweat, nasal fluids and saliva. For many years, chlorine or bromine based chemicals have been the standard disinfectants used in swimming pool water treatment.
However, studies have proven that the use of these chemicals can have health consequences due to the formation of reaction by-products, mainly chlorinated organic compounds and chloramines. Chloramines are responsible for eye, ear and throat irritation as well as the presence of strong "chlorine" odour. In a number of cases, stable compounds can be formed, which can only be removed from the swimming pool by complete water change of the pool.
Certain viruses, amoebae and cysts are also not inactivated at the chemical dosage levels normally used for pool water treatment.
While swim training may improve fitness and reduce morbidity associated with asthma, there is both anecdotal and scientific information to suggest that there are health-related problems associated with swimming in chemically-treated pool water. Swimming pool water is disinfected in the interests of public health, although it would appear that chemical disinfection of the pool water may be the cause of many of the health-related problems that have been reported.
