Maintaining the Optimal Water Quality in a heated swimming pool is essential for an enjoyable swimming experience. However, a variety of challenges can arise that cause common problems with water quality in temperature-controlled pools. In this article, we explore these common issues and discuss some effective solutions to ensure a safe and comfortable environment for swimmers.

Frequently asked questions about water quality in heated swimming pools

Ⅰ、If trichlorine or dichlorine products are put into an indoor pool, an over-stable situation will occur, resulting in a strong indoor chlorine smell and the production of chloramines, which will make swimmers feel uncomfortable. In addition, the water quality must be frequently changed, increasing operating costs. . This is due to excessive addition or improper mixing, so carefully control the amount and use appropriate mixing methods.

Why do I smell a strong chlorine smell?


Even if a small amount of disinfectant is added (tablets) to an indoor swimming pool, there will be an obvious chlorine smell, which is not necessarily related to excessive use of disinfectant. In fact, it is chloramines, or combined chlorine, that cause the smell of chlorine. Among them, chloramine, dichloramine, trichloramine, etc. are one of them. In higher concentrations, trichloramine can even produce an irritating gas similar to tear gas.

Studies have shown that, even when the free residual chlorine concentration in swimming pool water exceeds 10 ppm, there is still no chlorine smell. Therefore, simply measuring the concentration of free chlorine cannot accurately reflect the chlorine smell in the water.

Combined chlorine (chloramine) is a residual after disinfection. It interacts with isocyanuric acid in swimming pool water and human metabolites (sweat, urine, saliva, nasal mucus, skin metabolites, etc.) to generate chlorine-containing odor. organic matter.

How do we deal with chlorine smell?

According to the chemical equation, increasing the amount of disinfectant can help remove combined chlorine and generate nitrogen and other substances to be discharged outdoors. This adjustment process needs to be carried out under professional monitoring to ensure stable water quality and compliance with health standards. When more disinfectant is used, large amounts of nitrogen are produced, and more room ventilation will help better remove these harmful gases and reduce unpleasant odors. Regularly remove organic garbage from the pool water, control the organic load in the water, maintain the balance of the water environment, and help reduce the production of dissolved chlorine.

Ⅱ、If tourists urinate frequently, the urea content in the swimming pool will increase. Excessive urea content will not only have an adverse impact on water quality, but will also react chemically with other chemicals to produce harmful substances.

By increasing the concentration of added chlorine, it is ensured that the disinfectant in the water is effective in degrading urea. Or add appropriate oxidants, such as ozone, hydrogen peroxide, etc., to the water to help oxidize urea and reduce its pollution to water. Perform regular or routine cleaning of the filtration system to ensure effective removal of organic waste and urea in wastewater. An effective filtration system helps keep water clean and balanced.

Ⅲ、Disinfectant has the characteristics of strong irritation, strong irritation and unstable pH, which can irritate the eyes and skin of swimmers. Reasons for this phenomenon include: using too much disinfectant or using it improperly. The above problems can be solved by adjusting the dosage of fungicides and using pH stabilizers.

Ⅳ、Automatically add chlorine tablets in the machine room with a batching bucket. Because the smell of indoor chlorine is too strong, we dare not enter, and metal equipment and pipe fittings are also corroded. To solve this problem, you can add some ventilation devices in the computer room, adopt a gentler dosing method, and use anti-corrosion materials to make equipment and pipes.



In conclusion, if you want to solve this problem, you must take the initiative and respond proactively. Regular monitoring, proper chemical treatment, and proper filtration are crucial to maintaining ecological balance and cleanliness of water. As long as you stay alert and take appropriate measures in a timely manner, you can enjoy a well-controlled, comfortable, and hygienic swimming pool.
