As an important place for people to recreate and exercise, the safety of the water in swimming pools is of paramount importance.To ensure that the pool water is hygienic and safe, the use of the right sanitizer is essential.This article will introduce several common types of pool water sanitizers and discuss the water quality indicators that need to be tested during their use.
Bleach is a widely used pool sanitizer whose main ingredient is a mixture of sodium hypochlorite and calcium chloride calcium hydroxide.It has a strong bactericidal bleaching effect and can effectively kill bacteria, viruses and other microorganisms in pool water.However, bleach produces a distinctly irritating odor and is prone to chemical reactions when used, so care needs to be taken with storage and use conditions.
Sodium hypochlorite (bleach)
Sodium hypochlorite is another common pool sanitizer that is highly oxidizing and bactericidal.Compared to bleach, sodium hypochlorite has a relatively low irritating odor, but again, care needs to be taken for its safe use.
Trichloroisocyanuric acid (TCCA)
Trichloroisocyanuric acid is a highly effective, broad-spectrum disinfectant that kills bacteria, viruses, fungi, and other microorganisms.It has a stable disinfection effect and a relatively light odor.However, trichloroisocyanuric acid is a chemical hazard and requires special attention to safety during storage and transportation.
sodium dichloroisocyanurate dihydrate
Sodium dichloroisocyanurate dihydrate is also a commonly used pool disinfectant, which provides efficient and stable disinfection and is harmless to humans.In the market, this sanitizer is popular for its mild odor and stable performance.
When using the above sanitizers, the following water quality indicators need to be tested regularly in order to ensure the safety and quality of pool water:
Free residual chlorine is an important indicator of the effectiveness of pool water disinfection.It reflects the concentration of disinfectant remaining in the pool water to ensure that the water has a sustained disinfecting capacity to prevent bacterial repopulation and cross-infection.
The chemical chlorine residual is the concentration of chlorine sanitizer present in the pool water in a chemical state such as chlorine-ammonia.Compound residual chlorine is a strong irritant and may cause adverse effects on human health, so its concentration needs to be limited.
Cyanuric acid is a metabolite of disinfectants such as sodium dichloroisocyanurate and sodium trichloroisocyanurate.Cyanuric acid accumulates in pool water and too much of it can interfere with sanitizing effectiveness.Therefore, monitoring and control of cyanuric acid is required when using these disinfectants.
Turbidity is a measure of the clarity of pool water.It reflects the amount of suspended contaminant particles in the pool water.High turbidity not only affects the swimming sensation of swimmers, but also may affect the lifeguard's vision and increase the risk of accidents.
The pH level is a measure of the acidity or alkalinity of pool water.An environment that is too acidic or too alkaline tends to cause eye and skin irritation to swimmers.Therefore, the pH level of pool water needs to be tested and adjusted regularly to keep it within the appropriate range.
Urea is one of the most important indicators of the degree of contamination of swimming pool water.It is mainly derived from human sweat, secretions and excretions.High levels of urea indicate that the pool water has been contaminated and needs to be replaced or treated in a timely manner.
In summary, choosing the right pool sanitizer and regularly testing water quality indicators are key to ensuring pool water safety and sanitation.Swimming pool water quality monitor can guarantee the safety of water quality, to protect our health, Erun environmental protection production of swimming pool water quality tester has portable and laboratory desktop and other testing instruments, a full range of disinfectants include water quality testing indicators, If you need details and a quote you can contact customer service directly.
