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 ...
To kill pathogens and help prevent recreational water illnesses, pool operators must maintain proper levels of chlorine or another sanitizer. [10] [11] Over time, calcium from municipal water tends to accumulate, developing salt deposits in the swimming pool walls and equipment (filters, pumps), reducing their effectiveness.
The product of the process, sodium hypochlorite, provides 0.7% to 1% chlorine. Anything below the concentration of 1% chlorine is considered a non-hazardous chemical [according to whom?] although still a very effective disinfectant. The sodium hypochlorite produced is in the range of pH 6-7.5, relatively neutral in regards to acidity or baseness.

The San Francisco Bay Salt Ponds are a roughly 16,500-acre (6,700 ha) part of the San Francisco Bay that have been used as salt evaporation ponds since the California Gold Rush era. Most of the ponds were once wetlands in the cities of Redwood City , Newark , and Hayward , and other parts of the bay.
By far most chlorine is manufactured from table salt (NaCl) by electrolysis in the chlor-alkali process. The resulting gas at atmospheric pressures is liquified at high pressure. The liquefied gas is transported and used as such. [citation needed] As a strong oxidizing agent, chlorine kills via the oxidation of organic molecules. [16]
An AA battery in a glass of tap water with salt showing hydrogen produced at the negative terminal. Electrolysed water (also electrolyzed water, EOW, ECA, electrolyzed oxidizing water, electro-activated water, super-oxidized solution or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride.
