Saltwater Chlorination

Though traditional chlorine pools have been a suburban backyard staple for several decades, many homeowners are now deciding to switch to saltwater swimming pools. In addition to being a healthy alternative for your skin, saltwater swimming pools have several advantages over chlorine pools, including fewer chemicals, lower cost of upkeep, and minimal maintenance.

How Saltwater Chlorination Works

Before we get to the advantages let's take a quick look at how a saltwater vs. chlorinated pool works.

First of all, you need to know that a saltwater pool actually has chlorine.  The key difference is that in a standard chlorinated pool, chlorine is added manually on an ongoing basis to dissolve in the water.  In a saltwater pool, a regenerative process creates the chlorine. A saltwater purification system provides on-site production of the sanitizer necessary to maintain water in a safe, healthy and algae-free condition. Sanitizer is produced automatically, within the water itself, and involves no handling, storage or adding of chemicals to the water.  A saltwater sanitizing system, properly sized for its application, will eliminate the need to purchase sanitizing chemicals such as pool chlorine.  

First, the water in the pool is converted to saltwater, creating a mild saline solution.  In fact, the concentration of salt in the water of a saltwater pool is about 1/10th to 1/12th as salty as the ocean, so it is very mild.  The salt used is standard sodium chloride.  That’s the same stuff you have in your salt shaker at home.

Next, a chlorine generator is added to the pool’s filtration system.  This is simply a device that the water passes through as it circulates throughout the day.  This is where the chlorination happens.  When pool salt is dissolved in pool water and then subjected to simple electrolysis the chloride portion of the salt (sodium chloride) is transformed into an effective sanitizer, which has the ability to oxidize (kill) bacteria, virus, algae and other such radicals which would otherwise flourish in the water. The chlorine generator actually uses the salt to produce a chlorine gas that dissolves into the water.  This is what keeps the water clean.  This process is reversible, so it does not consume the salt, which is simply used over and over again. However, if you don’t clean the cells in chlorine generators, those calcified and corroded cells will produce little chlorine. When that chlorine breaks down it turns into salt.  That’s the beauty of the system.  The process just keeps going in a cycle.

Advantages to Saltwater Pools

Saltwater pools are on the rise as an alternative to traditional chlorine-based pools. Aside from being a more natural option, saltwater pools have a number of advantages. They don't require you to buy, store, or handle a lot of chemicals. These pools also need less routine maintenance. Although they are more expensive upfront, they pay for themselves after a few years because of reduced running costs. If you are thinking about installing a pool in your home, you should consider getting a saltwater swimming pool.

Comfort

One of the first advantages of saltwater swimming pools is the level of comfort you experience. Salt is softer on your skin than chlorine. Also, chlorine has the tendency to cause red eyes, itchy skin, and discolored hair. If you use plan to use your saltwater swimming pool on a regular basis, you won't have to suffer any of those symptoms of chlorine.

Chemicals

Another advantage of saltwater swimming pools is the lowered use of chemicals. People who own saltwater pools don't have to store and handle toxic chemicals on a regular basis. This means that a saltwater swimming pool is more environmentally safe. You also won't have to suffer the odor of chlorine anymore. The levels of chlorine in the water are low while still being effective. This also means that you won't have to deal with dry skin, green hair, and fading swimming suits.

Maintenance

Lower maintenance is also one of the advantages of saltwater swimming pools. They virtually clean themselves and require much less attention than pools that just use chlorine. The chlorine generator converts salt into chlorine, so you don't have to keep a constant check on the water sanitation. Algae does not grow as rapidly in saltwater pools because of the low stabilizer levels. Stabilizer is a chemical added to offset the harshness of chlorine. Because saltwater pools don't have the chemical chlorine, a stabilizer isn't required.

Cost

Over time, you will save money with a saltwater pool. While the best pool options are initially a lot more expensive to put in, they are a more cost-effective system in the end. Converting your traditional pool to a saltwater pool is not terribly expensive. Even with the extra expenses, you will make up for that loss after about two years. For many, this is one of the advantages. Chlorine is very expensive, and as compared, the amount of salt you'll use during a year is very inexpensive.

Health Benefits

Salt is a lot softer on skin, hair and eyes then chlorine. Chlorine as a chemical form consists of added chemicals to help stabilize the product, these additives cause irritation. This means there are many health benefits of a saltwater pool versus a chlorine pool, including: No red irritated eyes, no itchy, irritated skin, they are less harsh on your hair and they are far more suitable for asthma and allergy sufferers.

Versatility

Saltwater systems can be used with any body of water-- whether it's a small hot tub for the home or a large commercial pool. In fact, saltwater purification systems are easy to install and can even be completed by the homeowner.
