Salt water chlorination is the development of electrolysis of salt water.
The electrodes produce chlorine and
hydrogen in vaporous form at a constant rate resolute by the salinity of the pool water.
The electrodes produce chlorine and
hydrogen in vaporous form at a constant rate resolute by the salinity of the pool water.
It is important to
maintain correct salinity levels or the chlorination production rate declines.
While hydrogen may be liberated
as a gas the chlorine rapidly dissolves to form "free chlorine"
and follows the usual chlorine swimming pool
chemistry, except that the chloride ion may reorganization and be available again
for conversion in electrolysis. Salt
water chlorination does not have the ability to respond passably to shock
loadings and a backup ceaseless
dosing system or a bank of electrolysis units should also be provided.
Overnight and supplementary slug hand
dosing with chlorine compounds may be mandatory. Slug dosing should
never be done within three hours before
bathers are known to the swimming pool or spa pool or while people are swim.
