The Most Effective Disinfectants For Swimming Pools

The best disinfectant for swimming pools is one that has a high concentration of chlorine. This type of disinfectant is ideal for residential pools. It has the advantage of a slow dissolving time, a low concentration, and an easy application process. However, the right concentration for your pool requires a delicate balance between disinfecting the water and making it safe for swimmers. The use of stabilizers can help achieve the perfect balance. For people who are looking for swimming pool disinfection, this article is useful for them.


Chlorine is a commonly used disinfectant in swimming pools. It works to disinfect water and surface bacteria. This compound is found in water from various sources, including urine and perspiration. However, chlorine is not without its drawbacks. It produces a strong chlorine smell, which can be irritating to swimmers.


Although chloramines and bromine are highly effective disinfectants, the former is more environmentally friendly and milder on the skin and eyes. The difference between chlorine and bromine’s effectiveness depends on your swimming pool’s conditions and the type of water used. For example, chloramines can discolor swimmers’ skin or even fade the color of swimsuits. Bromine is less harsh and does not produce the chemical odor of chlorine. It is also less likely to cause asthma attacks.

Liquid sodium hypochlorite:

There are a few different types of chlorine. Dichlor is a common choice because of its neutral pH and quick dissolving nature. However, it is not the best choice for swimming pools because it corrodes metals. Because of this, it should never be used on a pool during the cold months. Because of this, it will cause staining and etching of the water.

Liquid sodium hypochlorite creates a gas called hypochlorous acid when it comes in contact with water. Depending on the pH of the water, it then dissociates into a hypochlorous ion. Hypochlorous ions have a very active killing effect and can penetrate the cell walls of microorganisms. Once inside the cell, the acid destroys the internal structure of the organism, causing its death.


Ozone is a highly effective disinfectant for swimming pools. Unlike chlorine, which has harsh chemicals and unpleasant side effects, ozone will not harm swimmers. It can be produced naturally or artificial. A quality ozone system can reduce the amount of chlorine required by up to 90%. Moreover, the system can reduce the need for algaecide and shock treatments.
