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 ...

3. Aqion - Wikipedia

   en.wikipedia.org/wiki/Aqion

   In order to flatten the steep learning curve aqion provides an introduction to fundamental water-related topics in form of a "chemical pocket calculator". Second. The program mediates between two terminological concepts: The calculations are performed in the "scientific realm" of thermodynamics (activities, speciation, log K values, ionic ...

4. Swimming pool sanitation - Wikipedia

   en.wikipedia.org/wiki/Swimming_pool_sanitation

   An electrically operated water pump is the prime motivator in recirculating the water from the pool. Water is forced through a filter and then returned to the pool. Using a water pump by itself is often not sufficient to completely sanitize a pool. Commercial and public pool pumps usually run 24 hours a day for the entire operating season of ...

5. 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. Saline water - Wikipedia

   en.wikipedia.org/wiki/Saline_water

   Saline water (more commonly known as salt water) is water that contains a high concentration of dissolved salts (mainly sodium chloride). On the United States Geological Survey (USGS) salinity scale, saline water is saltier than brackish water , but less salty than brine .

7. Sodium thiosulfate - Wikipedia

   en.wikipedia.org/wiki/Sodium_thiosulfate

   It is used to dechlorinate tap water including lowering chlorine levels for use in aquariums, swimming pools, and spas (e.g., following superchlorination) and within water treatment plants to treat settled backwash water prior to release into rivers. [2] The reduction reaction is analogous to the iodine reduction reaction.
