A saltwater pool system is an electrolytic cell
that is installed inline with the pool plumbing. Salt is added to the pool water to obtain a low level concentration and,
as the saline pool water passes through the electrolytic cell, chlorine is produced. The chlorine then breaks down into salt
and is continuously regenerated. The addition of more salt is needed only due to bather splash out and dilution by rain. The
level of salt used by the system is very low and most people barely notice it.
One of the benefits of this system
is that, because chlorine is being produced continuously at a very low level, the irritation associated with higher chlorine
levels from weekly chlorination is eliminated. As the water passes through the cell it is “shocked,” burning off the bad
“combined” chlorines that are often associated with swimmer irritation and potential algae problems.
For those who
like to keep the pool heated, the salt system allows the service technician to eliminate the need to run higher chlorine
levels as he tries to overcompensate for the residual lost due to the “gassing” off of the chlorine caused by the heated water.
