Salt water chlorination is a process that uses dissolved salt as a store for the chlorination system. The salt generator uses direct electric current in the presence of dissolved salt to separate elements, thus producing hypochlorous acid and sodium hypochlorite, which are the most commonly used sanitizing agents in pools. This means a saltwater pool is not chlorine-free, it simply uses a salt generator instead of adding chlorine directly to the water.
Advantages of a saltwater system
- It is the most convenient over time.
- There is a constant delivery of pure, chlorine-based sanitizer to the water.
- It is healthier for swimmers over time.
- It is less irritating to people who are sensitive to chlorine.
- It is softer on skin.
- There is no hair color damage.
- It is cheaper to maintain throughout the year.
- It reduces irritating chloramines.
Disadvantages of a saltwater system
- The initial cost, maintenance and replacement of cells can be expensive.
- Salt can be corrosive to some metals that are improperly maintained.
- Scaling or calcium build up can occur naturally.
Liquid Chlorination is the process of adding or mixing a large amount of chlorine or hypochlorite to the pool water. This process is done to reduce the bacterial and algal residue in the pool water. Swimming pools that are being liquid chlorinated should not be swum in or accidentally ingested until the sodium hypochlorite level in the water decreases. Sodium hypochlorite should never be mixed with calcium hypochlorite due to a risk of explosion.
Advantages of a liquid chlorine system
- It kills bacteria faster than salt chlorination.
- It prevents the spread of waterborne diseases such as cholera, dysentery and typhoid.
- Produces compounds known as disinfection byproducts like trihalomethanes (THMs) and haloacetic acids (HAAs), which are responsible for health hazards over time.
- Long exposure and ingesting large amounts of chlorine in the body can cause liver and kidney cancer, as well as a decrease in regular brain activity characterized by sleepiness or sedation.
- Chlorine can disappear too quickly in the water system due to circumstances like heavy rain or poor maintenance.
- Chlorine has an unfavorable taste and odor.
