Salt treatment for pools works through a process called electrolysis, where salt (sodium chloride) is converted into chlorine automatically. This occurs when the chlorine generator, installed in the pool’s filtration system, passes an electric current through the salt water. Electrolysis separates the salt elements, producing chlorine that is immediately dissolved in the water, ensuring effective disinfection and eliminating microorganisms, bacteria, and algae.
The main components of this system include the chlorine generator and salt meter, which work together to ensure that the amount of salt in the water is always within ideal levels. The generator is responsible for performing electrolysis, while the salt meter continuously monitors salt concentration, ensuring the process works optimally. This automatic monitoring greatly simplifies maintenance, as there’s no need to manually add chlorine to the pool.
The amount of salt needed for the system to function is relatively low, with a recommended concentration of approximately 3 grams of salt per liter of water, which is significantly less than the amount of salt found in seawater. The table below demonstrates the ideal salt quantities for different pool volumes:
| Pool Volume (liters) | Salt Quantity (kg) |
