Are you still using chlorine tablets to clean your pool?

Without a complete preparation of the pool, it cannot be a safe environment for its users. Water testing, recirculation, filtration, mechanical cleaning and water disinfection are some of the traditional and necessary ways to do this.

For a long time, the only available way to disinfect pools was chlorine in tablet, liquid and powder form. Chlorine has strong antibacterial properties, but it also has some very significant disadvantages, which we will cover in this article.

Chlorine for swimming pools – disadvantages

Chemical preparations containing chlorine are used to disinfect pools. When chlorine enters a liquid environment, it interacts with the simplest bacteria, viruses, fungi. Thanks to its disinfecting ability, it penetrates the organisms themselves, causes mutations, cell disintegration and cellular death.

However, it is often practised to supersaturate the pool water with chlorine to ensure its effective disinfection. This, unfortunately, creates conditions for the deterioration of pool users’ health.

To avoid systematic and constant disinfection with chlorine, people resort to the so-called “shock” treatment with chlorine, ten times higher doses than the standard one used for this purpose. As a result of the excessive amount of chlorine in the pool, practically all bacteria die, the water and the walls of the pool are cleared of algae spores. However, after the shock treatment of pool water with chlorine, it becomes unfit for bathing until the chlorine content in it is reduced to acceptable limits.

What chemical reactions occur and are they dangerous?

When chlorine is added to water, a chemical reaction occurs and a weak acid called hypochlorous acid is released. This acid can penetrate the cell walls of microbes such as bacteria and viruses, so it attacks and kills the microbes effectively. Chlorine-based disinfectants are very effective against a wide range of viruses and bacteria, and under appropriate conditions, even against parasites.

Chlorine works by destroying the proteins in bacterial cells, causing the bacteria to die. It can also kill viruses, although the method it uses to kill viruses is still not clear. Some experts believe that chlorine damages the proteins in the cells of viruses, making them unable to penetrate human cells and cause infection.

Although chlorine can kill most germs, it doesn’t always work immediately. According to the Centers for Disease Control and Prevention, E. coli, a common bacteria spread through faeces, dies in less than a minute when exposed to the concentration of chlorine in a pool, while hepatitis A, a virus that affects the liver, is destroyed in 16 minutes.

Chlorine may take even longer to kill gastrointestinal parasites. The parasite called Giardia takes 45 minutes to die, while Cryptosporidium, which causes a serious diarrhoeal disease, takes 10.6 days to die after exposure to chlorine.

Chlorine is used in pools to kill germs, but when it comes into contact with the bodily fluids that swimmers bring into the pool (such as sweat and urine), it forms compounds called chloramines. Chloramines in water, such as dichloramine and trichloramine, irritate the skin, eyes, and respiratory tract (including the nose) when they are released as a gas from the water and into the air above it, especially indoors. In addition, chloramines can contribute to corrosion of metals around the water site and in air handling systems.

What can pool operators do to prevent or get rid of chloramines?

Chloramines are a type of combined chlorine that forms in water and is then released as a gas into the air above the water. Most health authorities limit the amount of combined chlorine in water to 0.4 ppm or less.

Chloramines can accumulate in the water and in the air around pools if there is not enough fresh air. This is especially valid for indoor water facilities, where the air processing systems do not bring in enough fresh air and do not exhaust enough chloramine-contaminated air. Chloramines, which are released as a gas from water, are heavier than air. This means that they settle on the surface of the water, where they can cause negative health effects for swimmers and those working in the facility.

Indoor air processing systems may remove moisture from the air, but they are not always designed to bring in enough fresh air or remove enough chloramine-contaminated air, so pool operators are advised to consult technical representatives on how to get the most out of their air processing system in order to reduce the accumulation of chloramines. If chloramines are not flushed out, they will accumulate in the water and cause health effects in swimmers.

Chloramines are the cause of the specific smell around the pool. Excessive chloramines in the pool can cause:

Conjunctivitis;

Sinusitis;

Allergic reactions.

In addition to these negative effects, chloramines reduce the effectiveness of free chlorine. Pool water chlorination is not effective until they are neutralized.

Synthetic chlorine in the form of tablets, liquids and powders in the pool is a familiar option for disinfecting water, but today there are much more environmentally friendly, harmless and effective methods of disinfecting and purifying water, which are even cheaper in the long run.

Heathy Swim provides an environmentally friendly, 100% effective and healthy chemical removal solution as a way to purify pool water through an innovative method that is completely harmless and easy to use. Chlorine values in the pool can be monitored and controlled from a distance through a mobile application so that they can be kept within the legal limits, which in turn guarantees the good health of users.

Healthy Swim’s innovative pool purification technology is applicable to both private and public pools, the hotel business and anyone who wants to enjoy clean water in their own pool. The entire maintenance process is digitalized, resulting in money savings and easy and convenient management. And the users’ experience in a pool with soft and crystal water is incomparable.
