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 ...
When any of these pool chemicals are used, it is very important to keep the pH of the pool in the range 7.2 to 7.8 – according to the Langelier Saturation Index, or 7.8 to 8.2 – according to the Hamilton Index; higher pH drastically reduces the sanitizing power of the chlorine due to reduced oxidation-reduction potential (ORP), while lower ...

Active systems are often using a wearable on the swimmer, such as a wristband, that monitors the behaviour and position of the swimmer. If the swimmer is detected to be under water för a certain period, an alarm is triggered and through acoustic underwater communication from the wristband to receivers installed in the pool the alarm is transferred to on-site lifeguards that immediately can ...
The chemicals may be cations, anions, molecules or agglomerations on the order of one thousand or fewer molecules, so long as a soluble micro-granule is formed. More exotic and harmful elements of TDS are pesticides arising from surface runoff. Certain naturally occurring total dissolved solids arise from the weathering and dissolution of rocks ...
Chemicals that serve this function are reducing agents which reduce chlorine species to chloride, which is harmless to life. Some compounds employed in commercial dechlorinators are sodium thiosulfate , sodium hydroxymethanesulfonate, and sodium hydroxymethane sulfinic acid.

A swimming pool, swimming bath, wading pool, paddling pool, or simply pool, is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in-ground pools) or built above ground (as a freestanding construction or as part of a building or other larger structure), and may be found as a ...
