Salt

In-line salt generators, also known as salt chlorinators or saltwater generators, are devices installed directly into a pool’s plumbing system to convert salt into chlorine. 

The process involves several key steps:

1. Salt Dissolution in Water: Initially, a specific amount of pool-grade salt 

(sodium chloride) is added directly to the pool water, dissolving completely. The salt concentration in a typical saltwater pool ranges between 2,500 to 3,500 parts per million (ppm), which is much lower than the concentration in seawater.

2. Electrolysis in the Generator Cell: As water circulates through the pool’s filtration and plumbing system, it passes through the in-line generator cell. This cell contains specially coated titanium plates that are electrically charged. When the salted water flows through the cell, the electrical current splits the salt (NaCl) molecules into sodium (Na) and chlorine (Cl).

3. Formation of Chlorine: The chlorine atoms produced in the generator cell combine with water to form hypochlorous acid (HOCl), which is the primary sanitizing agent that kills bacteria, algae, and other pathogens in the  pool. This process of electrolysis continuously generates chlorine as water circulates through the system.

4. Recycling of Salt: After the chlorine does its job disinfecting the pool, it reverts  to salt in a process known as recombination. This cyclical process allows the salt to remain in the water and be reused over and over, reducing the  need for frequent salt replenishment.
