Water quality should be regularly monitored and maintained with the utmost care for ultimate safety. Proper testing and regular maintenance of swimming pool is essential for ensuring safety and water quality. Many swimming pool treatment systems are available to keep your pool water clean and clear.

During this article, we will discuss the most common water treatment systems, along with their advantages and disadvantages.

The importance of choosing the right swimming pool treatment system

Different swimming pool treatment systems are designed to work with different types of pool water, such as salt water, chlorine, and ultraviolet light systems. Each system has different advantages and disadvantages, such as the cost and maintenance of the system, as well as the quality of the water produced.

The use of Chlorine for swimming pool treatment

Chlorination is the most commonly used swimming pool treatment in private pools. It uses chlorine to disinfect the water, eliminating bacteria, viruses, and other harmful microorganisms. It also helps to keep swimmers safe by reducing the risk of infection. Chlorine can be added to water in the form of tablets, granules, liquids, or gases. Dosage is essential to ensure effective disinfection without irritation.


Chlorine is highly effective against a wide range of microorganisms. It’s also relatively affordable and easy to use, making it a popular choice for pool owners. For instance, chlorine tablets are the most common form of chlorine used to sanitize pool water, since they are easy to add to the skimmer basket and dissolve slowly over time.


There are, however, some disadvantages associated with chlorine. It is possible for chlorine to cause irritation of the skin and eyes, particularly when the dosage is incorrect. Maintaining an appropriate level of disinfection requires regular monitoring and adjustment. Additionally, chlorine can alter the pH balance of water, requiring further adjustments.

Swimming pool treatment with bromine

The use of bromine as an alternative to chlorine is beneficial, as it is not known to have any adverse effects on the skin or eyes. The fact that it is effective even at high water temperatures makes it an ideal choice for spas and jacuzzis. However, it can also be used as a swimming pool treatment.


Bromine does not produce as many irritating by-products as chlorine, which makes it a safer choice for both humans and the environment. Additionally, it is effective over a broad pH range, allowing its use in a variety of situations. Furthermore, bromine does not have a strong odor, unlike chlorine; it is therefore the most suitable treatment for indoor pools.


There is no doubt that bromine is more expensive than chlorine in general. It is important to note that bromine is not as powerful an oxidizer as chlorine, which means that it may not be able to eliminate certain bacteria. Additionally, the use of bromine can also require specialized dosing equipment, which may result in an increase in the initial costs as well.

Active oxygen as a swimming pool treatment

Active oxygen oxidizes organic matter, killing bacteria and other microorganisms that can contaminate pool water. Often, this treatment is used in conjunction with other disinfection systems to maximize their effectiveness.


Active oxygen is a natural and effective way to sanitize swimming pools.  There are many advantages to using it. It does not cause irritation to the skin or eyes. A second advantage of this product is that it does not alter the pH of the water, which makes its maintenance easier. Lastly, this swimming pool treatment is odorless, making bathing more pleasant.


It should be noted, however, that active oxygen may be more expensive than other methods of water treatment. It is highly sensitive to water temperature changes; therefore, the dosage should be increased as the temperature of the water rises. Furthermore, for the treatment to be properly dosed, specialized equipment called a dosifier and professional installation are required.

    Let the experts design your pool.


    Saltwater swimming pool treatment

    The saltwater pool treatment uses an electrochemical process, electrolysis, to split salt molecules into sodium and chlorine ions. These ions are then released into the pool. The chlorine helps keep the pool clean, while the sodium ions soften the water, softening it on the skin.


    Saltwater treatment is gentler on the skin and eyes, since the water does not contain the harsh chemicals found in chlorine pools. Additionally, saltwater pools require less maintenance since they don’t need to be monitored as closely as chlorine pools.


    It is imperative to note, however, that saltwater treatment requires a salt chlorinator. This will increase the initial cost of the project. Additionally, although salt is less irritating to the skin than chlorine, some individuals may still experience irritation.

    Pool water treatment by ozone

    Ozone is a powerful oxidizing agent that instantly destroys micro-organisms. It works by breaking down the cell walls of the micro-organisms, killing them within seconds.


    Pool water can be effectively treated with ozone to eliminate bacteria, viruses, and other microorganisms. There are no chemicals added to the water, and it does not cause irritation to the skin or eyes.


    However, this kind of water treatment requires specialized equipment and can be costly to install and maintain. What’s more, ozone offers no residual effect, so other disinfection methods may be required.

    Pool ionizer

    Pool ionizer releases copper and silver ions toxic to bacteria and algae. They attach to the cell walls of bacteria and algae, preventing reproduction. This helps keep the pool water clean and clear. Silver ions kill algae more effectively, while copper ions are more useful in removing bacteria.


    Pool ionizers are beneficial because they do not produce by-products. Therefore, pool water does not cause irritation to the skin or eyes. Moreover, there is no smell or taste to the water. The copper ions prevent algae from growing.


    However, pool ionizers can be costly to install and maintain. It takes hours to become effective, and the pool may develop stains during this time due to an imbalance of ions. Test kits that monitor pool ionizer performance mainly measure copper.

    Things to consider when choosing a swimming pool treatment system

    Given the large number of options available on the market, it may be difficult to choose the correct swimming pool treatment system. The process of making this decision can, however, be simplified if a methodical approach is taken.

    Different treatment systems have different features and benefits that may be important for your pool, such as the type of chemical used, the amount of maintenance required, the cost of the system, and its ability to control algae and bacteria. By researching and evaluating the various options, you can determine which one is best for your pool.

    Needs identification

    Before choosing a water treatment system, clearly define your needs and priorities.

    • What’s our pool size?
    • What’s your pool usage like?
    • Do you worry about chlorine eye and skin problems? 

    Your answers to these questions will assist in determining the type of system that is most appropriate for you.

    Analyzing your options

    Once you have identified your needs, you are able to determine what options are available to you. You should learn how each of these systems works, as well as their advantages and disadvantages, installation and operation costs, and maintenance requirements.
