  2. 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 ...

    en.wikipedia.org/wiki/Swimming_pool_sanitation

    If the pool's water pump is operational water is drawn from the pool over a floating hinged weir (operating from a vertical position to a 90-degree angle away from the pool, in order to stop leaves and debris being back-flooded into the pool by wave action), and down into a removable "skimmer basket", the purpose of which is to entrap leaves ...

  4. Shock chlorination - Wikipedia

    en.wikipedia.org/wiki/Shock_chlorination

    Shock chlorination is a process used in many swimming pools, water wells, springs, and other water sources to reduce the bacterial and algal residue in the water. Shock chlorination is performed by mixing a large amount of sodium hypochlorite, which can be in the form of a powder or a liquid such as chlorine bleach, into the water.

  6. Dealkalization of water - Wikipedia

    en.wikipedia.org/wiki/Dealkalization_of_water

    Alkalinity is a factor that most often dictates the amount of boiler blowdown. High alkalinity promotes boiler foaming and carryover and causes high amounts of boiler blowoff. When alkalinity is the limiting factor affecting the amount of blowdown, a dealkalizer will increase the cycles of concentrations and reduce blowdown and operating costs.

  7. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Sufficient alkalinity also reduces the corrosiveness of water to iron pipes. Acid (carbonic acid, hydrochloric acid or sulfuric acid) may be added to alkaline waters in some circumstances to lower the pH. Alkaline water (above pH 7.0) does not necessarily mean that lead or copper from the plumbing system will not be dissolved into the water.

  8. Alkalinity - Wikipedia

    en.wikipedia.org/wiki/Alkalinity

    Alkalinity (from Arabic: القلوية, romanized: al-qaly, lit. 'ashes of the saltwort') [1] is the capacity of water to resist acidification. [2] It should not be confused with basicity, which is an absolute measurement on the pH scale. Alkalinity is the strength of a buffer solution composed of weak acids and their conjugate bases.

  9. Alkali soil - Wikipedia

    en.wikipedia.org/wiki/Alkali_soil

    The causes of soil alkalinity can be natural or man-made: The natural cause is the presence of soil minerals producing sodium carbonate (Na 2 CO 3) and sodium bicarbonate (NaHCO 3) upon weathering. Coal-fired boilers / power plants, when using coal or lignite rich in limestone, produce ash containing calcium oxide.
