The benefits of our Salt Water Pool.

Salt-water pools might conjure up visions of invigorating ocean swims, but they have little in common with the briny environment. All pools need treatment to sanitize the water. Health threats of pool water include bacteria, viruses and other contaminants that thrive and grow if unchecked. Many swimmers who suffer side effects from traditional chlorination systems swear by the benefits of salt-water pools. Despite the benefits of salt-water pools, the methods used to sanitize them might come as a surprise to many.

Salt in Salt-Water Pools

The role of salt in salt-water pools is neither disinfection, nor improvement in buoyancy. Salt levels in pools are far below the salt concentration in ocean waters. Instead, salt acts as a continuous source of convertible chlorine.

Continuous Disinfection

Salt-water pool disinfection systems rely on chlorine to kill germs and neutralize contaminants in the water, just as traditional chlorine-based systems. A unit containing two slightly charged titanium plates allows the salt or NaCl to pass through them. In a process called electrolysis, the salt breaks down and reforms in water to form the hypochlorous acid responsible for disinfection in traditional chlorine-based systems. Because the salt is dissolved in the pool water, there is a continuous and steady supply of chlorine flowing into the pool.

By-products

When chlorine levels fall in traditional pools, usually due to lack of strict maintenance and testing, the level of unhealthy by-products or chloramines from the disinfection process remains intact. Usually, adequate levels of free chlorine further break down the chloramines that typically cause red itchy eyes, lung irritation and the smell often associated with chlorinated pools. Salt-water pools avoid the buildup of chloramines because the chlorine levels replenish themselves constantly and do not depend on pool owners or pool workers to add more chlorine to the water as needed.

Less Side Effects

The main benefit of salt-water pools is the lack of side effects often associated with traditionally chlorinated pools. Mary Pohlman, M.D., assistant professor of clinical medicine at Southern Illinois University School of Medicine and a member of the United States Masters Swimming Sports Medicine Committee, states that in addition to irritated eyes and skin, some swimmers suffer from lung irritation and asthma-like symptoms when contaminant levels overburden under-chlorinated pools.
