Do saltwater pools contain chlorine? Are saltwater pools ‘chlorine-free’?
There is a common misconception about saltwater pools and it is often used as a marketing term to imply that they are not chlorinated. This is not true as saltwater pools are NOT chlorine-free as they do contain chlorine. The difference between saltwater and fresh water pools is the method used for adding chlorine to the water to kill bacteria and sanitize the pool.
In saltwater pools, chlorine is generated by using an electrolysis process in an Electrolytic Chlorine Generator (ECG) that generates chlorine from salt (sodium chloride) by splitting the chlorine from the sodium, while in fresh water pools the chlorine produced in factories through electrolysis of sodium chloride (salt) solutions are added into the pool. This means, while saltwater pools produce chlorine at the pool itself, for fresh water pools, factory produced chlorine is dosed into the pool physically. Both types of pools often need other chemicals to be added to maintain correct pH levels and water clarity.
At DSA, both freshwater and saltwater pools use chlorine to keep bathers safe as chlorine is the most effective and proven disinfectant to kill bacteria and pathogens in the pool and maintain the safety of swimmers.
