The water in a swimming pool is constantly exposed to microbes and bacteria, so it\u2019s essential to carry out proper pool treatment<\/strong> to keep it clean and safe for users. Learn how to perform saltwater pool treatment<\/a> by understanding how salt electrolysis works and its main advantages.<\/p>\n

Swimming pool water disinfection<\/span><\/h2>\n

Even if a pool appears clear and clean, the water can still contain bacteria and microbes harmful to human health. These can cause intestinal problems, skin and eye irritation, or even lung infections.<\/p>\n

To prevent this, an appropriate pool treatment<\/strong> is required to maintain the main water properties and disinfect it by eliminating all microorganisms.<\/p>\n

Today, there are several suitable systems for disinfection and pool treatment<\/strong>, such as chlorine treatment<\/strong>, ultraviolet treatment<\/strong>, and saltwater pool treatment<\/strong>, also known as salt electrolysis disinfection, among others.<\/p>\n

Saltwater pool treatment<\/a><\/span><\/h2>\n

Saltwater pool treatment<\/strong>, also referred to as salt electrolysis disinfection, has long been successfully used in both public and private pools.<\/p>\n

Currently, more than 50% of private pools in Portugal use saltwater pool treatment<\/strong>. The process is very simple: just add a small amount of salt (table salt is suitable) directly into the pool water.<\/p>\n

The salt cell is installed in the pool\u2019s circulation system, and the water is treated through electrolysis.<\/p>\n

What is salt electrolysis?<\/span><\/h2>\n

Salt electrolysis refers to the process of breaking down salt into chlorine, which is then used to disinfect the pool.<\/p>\n

This pool treatment<\/strong> is a more economical and eco-friendly way to disinfect pool water, making it safe for swimming and free from bacteria and microbes.<\/p>\n

How does salt electrolysis work in practice?<\/span><\/h2>\n

\"Saltwater<\/p>\n

To perform salt electrolysis, you need a specific device installed, and then salt is added to the water to remove impurities. Typically, around 4 grams of salt are used per 1,000 litres of water.<\/p>\n

This saltwater pool treatment<\/strong><\/a> is highly effective, as it transforms salt molecules into a disinfectant that eliminates bacteria, microbes, and other fungi that may be present in the pool water.<\/p>\n

Once the salt is dissolved in the pool, the installed system generates a controlled electric current (via an electrode), converting the salt into chlorine. This ensures the water remains sanitised through the action of chlorine.<\/p>\n

At the end of the process, after the impurities have been oxidised, the chlorine is reconverted into salt\u2014meaning the salt remains in the pool water continuously.<\/p>\n

With this pool treatment<\/strong>, you only need to monitor the salt level along with the water’s alkalinity and pH parameters.<\/p>\n
