2. Swimming pool sanitation - Wikipedia

   en.wikipedia.org/wiki/Swimming_pool_sanitation

   Over time, calcium from municipal water tends to accumulate, developing salt deposits in the swimming pool walls and equipment (filters, pumps), reducing their effectiveness. Therefore, it is advised to either completely drain the pool, and refill it with fresh water, or recycle the existing pool water, using reverse osmosis. The advantage of ...

3. Salt water chlorination - Wikipedia

   en.wikipedia.org/wiki/Salt_water_chlorination

   Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...

4. Alkalinity - Wikipedia

   en.wikipedia.org/wiki/Alkalinity

   Alkalinity is frequently given as molar equivalents per liter of solution or per kilogram of solvent. In commercial (e.g. the swimming pool industry) and regulatory contexts, alkalinity might also be given in parts per million of equivalent calcium carbonate (ppm CaCO 3) [citation needed].

   Alkaline water is water that has a higher pH level than normal drinking water (between 7.5 and 9 for alkaline water versus 7 for normal drinking water). Alkaline water may come from springs or ...

6. Dealkalization of water - Wikipedia

   en.wikipedia.org/wiki/Dealkalization_of_water

   This exchange works well only with high alkalinity waters (40% to 80%), with capacities of 4 to 10 Kg/CF being obtained. The advantages of SBA resin dealkalization is that low-cost salt is used in place of the acid necessary for the SAC (strong acid cation) and un-lined steel tanks can be used."

7. Swimming pool bacteria - Wikipedia

   en.wikipedia.org/wiki/Swimming_Pool_Bacteria

   The team found that bacteria seemed to be more prevalent in outdoor pools. [4] Furthermore, they noted that the higher the pH of the pool, the more bacteria were present in the water. 20.2% of the bacteria in the pools were found to be S. aureus. [4] Another study reported two experiments involving a large pool and a small pool. [5]

8. Respiratory risks of indoor swimming pools - Wikipedia

   en.wikipedia.org/wiki/Respiratory_risks_of...

   Respiratory risks of indoor swimming pools can include coughing, wheezing, aggravated asthma, [1] and airway hyper-responsiveness (spasms of the bronchial tubes in the lungs causing coughing and chest tightness). The chemicals used for pool water disinfection can react with organic compounds in the water to create disinfection by-products or
