    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 ...

    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 ...

    en.wikipedia.org/wiki/Hypochlorous_acid

    Hypochlorous acid is an inorganic compound with the chemical formula Cl O H, also written as HClO, HOCl, or ClHO. [2] [3] Its structure is H−O−Cl.It is an acid that forms when chlorine dissolves in water, and itself partially dissociates, forming a hypochlorite anion, ClO −.

  6. Electrochlorination - Wikipedia

    en.wikipedia.org/wiki/Electrochlorination

    Electrochlorination is the next step in the evolution of this process. It chlorinates drinking water without producing environmental toxins. Unlike other chlorination techniques, electrochlorination generates no sludge or by-products other than hydrogen which must be managed safely.

  7. Lithium hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Lithium_hypochlorite

    Lithium hypochlorite is a chemical compound with the chemical formula of Li O Cl. It is the lithium salt of hypochlorous acid. It consists of lithium cations (Li +) and hypochlorite anions (− OCl). It is a colorless, crystalline compound. It has been used as a disinfectant for pools, and is also used as a reagent for some chemical reactions.
