The Science Behind Saltwater Pool Sanitation

Have you ever wondered about the science behind saltwater pool sanitation? How does it work? How is it possible to eliminate the use of traditional chlorine and still be effective?  In recent years, saltwater pools have gained popularity as an alternative to traditional chlorine-treated pools. Let’s take a closer look at the science behind saltwater pool sanitation and why it may be a better option for your swimming pool.

How Does Traditional Chlorine Work?

Chlorine is a strong oxidizing agent that is used to kill bacteria and viruses in the pool water. When chlorine is added to water, it forms hypochlorous acid (HOCl) and hypochlorite ion (OCl-). These two forms of chlorine are responsible for killing bacteria and viruses in the pool water. However, chlorine has its downsides. It has a distinct odor and can cause skin and eye irritation, especially if the levels are not properly balanced. In addition, chlorine-treated pools require regular maintenance to ensure the correct levels of chlorine are present. If the levels are too high, it can cause harm to swimmers, and if the levels are too low, the water becomes a breeding ground for bacteria and viruses.

How Do Saltwater Pools Work?

Saltwater pools use a generator to convert salt into chlorine. The generator works by electrolysis, which breaks down the salt (NaCl) into sodium hypochlorite (NaOCl) and hypochlorous acid (HOCl). These two forms of chlorine work together to kill bacteria and viruses in the pool water, just like in traditional chlorine-treated pools.

What’s the Biggest Difference?

The main difference is that saltwater pools use much lower levels of chlorine compared to traditional chlorine-treated pools. This lower level of chlorine reduces the odor and irritation that comes with traditional pools. In addition, saltwater pools require less maintenance because the generator constantly produces chlorine as needed, unlike traditional pools that require frequent monitoring and adding of chlorine.

Are Saltwater Pools Eco-Friendly? 

Saltwater pools are generally considered better for the environment. Traditional chlorine-treated pools require the constant addition of chlorine, which can be harmful to the environment if not disposed of properly. Saltwater pools, on the other hand, only require the addition of salt, which is a natural and abundant resource. Then balance your other chemicals into normal ranges.

Are Saltwater Pools Chlorine Free?

One common misconception about saltwater pools is that they are entirely chlorine free. As mentioned earlier, saltwater pools still use chlorine to sanitize the water, but at lower levels than traditional chlorine-treated pools. This misconception is likely due to the fact that saltwater pools do not have the distinct chlorine odor that traditional pools have.

Keep This in Mind About Saltwater Pool Sanitation

It is important to note that saltwater pools still require proper maintenance and balancing of chemicals to ensure the health and safety of swimmers. Regular monitoring of pH levels and alkalinity is necessary to prevent the growth of bacteria and algae in the water. The science behind saltwater pool sanitation is nothing short of fascinating, especially when you’re trying to determine the right sanitation option for your pool.  At Solaxx by AquaComfort Solutions, you’ll find the salt cell generator that meets your needs, whether you have an inground pool or an above-ground pool.
