Adding sanitizer is an important part of ensuring that your pool water is clean and sanitary.In this article, we'll take a closer look at why pool water should be sanitized and detail the indicators associated with water quality sanitizers.
Prevent microbial growth: The pool is an open environment where swimmers' sweat, dander, urine and other excretions, as well as cosmetic residues, enter the water, providing a breeding ground for bacteria, viruses and other microorganisms.These microorganisms not only affect water quality, but can also cause illness through skin contact and inhalation.Disinfectants can effectively kill or inhibit these microorganisms and reduce the risk of infection.
Control algae growth: Algae can multiply rapidly under the right conditions, leading to deterioration of water quality and affecting the swimmer's experience.Sanitizers inhibit the growth of algae and keep pool water clear and transparent.
Remove organic matter: Organic matter such as sweat and dander not only provide nutrients for microorganisms, but may also produce odors.Disinfectants break down these organics through oxidation, reducing odors and improving water quality.
Maintaining water balance: The use of sanitizers helps to maintain the stability of the pH, alkalinity and other chemical indicators of pool water to ensure that the water quality meets hygiene standards.
What are the water quality disinfectant indicators?
In pool water quality management, the use of sanitizers needs to follow certain targets to ensure safe and hygienic water quality.Here are a few key water sanitizer indicators:
Residual Chlorine: Residual chlorine refers to the amount of free chlorine remaining in the water and is an important indicator of disinfection effectiveness.Generally speaking, the residual chlorine in swimming pool water should be controlled between 0.3 and 0.5mg/L.If it is too low, it cannot effectively sterilize the water, and if it is too high, it may cause irritation or harm to human body.
pH: pH is a measure of the acidity or alkalinity of a body of water.The pH of pool water should be controlled between 7.2 and 7.8 to maintain water stability and comfort.A pH that is too high or too low will affect the sterilizing effect of the sanitizer and may corrode pool equipment.
Total Alkalinity: Total alkalinity is the total amount of alkaline material in the water and plays an important role in maintaining a stable pH level in pool water.Total alkalinity should be controlled between 60~200mg/L to ensure that the water quality remains stable when the swimming load changes.
Calcium hardness: Calcium hardness refers to the amount of calcium ions in the water, and is important for preventing scaling and corrosion in pool water.Calcium hardness should be controlled between 200~450mg/L to keep the water clear and transparent.
Total Dissolved Solids: Total dissolved solids is the total amount of solids such as salts and minerals dissolved in water.Although this indicator does not have a direct impact on the disinfection effect, too high a total dissolved solids content will affect the transparency and taste of the water, so it also needs to be controlled within a certain range.
In practice, pool managers should reasonably adjust the amount and type of disinfectant to be put into the pool according to the specific conditions of the pool (e.g., size, usage rate, water temperature, etc.) and the results of water quality tests to ensure that the water quality meets the hygiene standards.At the same time, water quality indicators should also be tested regularly and maintenance programs should be adjusted in a timely manner based on test results to provide a safe and healthy swimming environment for swimmers.
In conclusion, adding disinfectant is an important part of swimming pool water quality management. By following scientific water quality disinfectant indicators and reasonable maintenance programs, the cleanliness and hygiene of swimming pool water can be effectively guaranteed, bringing swimmers a pleasant swimming experience.
