A saltwater chlorinator

A saltwater chlorinator , also known as a salt chlorinator or saltwater generator, is a device used to chlorinate swimming pools and spa water using salt. Instead of using traditional chlorine tablets or liquid chlorine, a saltwater chlorinator uses an electrolysis process to convert salt into chlorine. Here's how it typically works: Salt is added to the pool water: The first step is to add salt to the pool water. The salt is dissolved, and the concentration is usually around 2,500 to 4,000 parts per million (ppm), which is much lower than seawater. Electrolysis cell generates chlorine: The saltwater chlorinator is connected to the pool's circulation system. As the pool water passes through the chlorinator's electrolysis cell, an electric current is applied to the cell's electrodes, which are typically coated with a thin layer of a special metal alloy. This process, known as electrolysis, causes the salt in the water to split into its component parts: sodium and chlori...
