There are many methods for disinfecting pool water. Below, we summarize the main methods, their advantages and disadvantages, and Piscinity\u2019s position. The effectiveness of water disinfection depends on water hardness and pH. Therefore, the first step is always to check and adjust the pH.<\/p>\n\n\n\n

(If using water from an artesian well, it is recommended to provide a recent water sample for analysis to ensure suitability.)<\/em><\/p>\n\n\n\n

pH Adjustment<\/h2>\n\n\n\n

The ideal pool water pH is between 7.2 and 7.6, with 7.4 being optimal. This is because:<\/p>\n\n\n\n

    \n
  • Human blood pH is 7.4.<\/li>\n\n\n\n
  • Most disinfectants lose effectiveness at pH above 7.8 (e.g., chlorine is only 20% effective above pH 7.8).<\/li>\n<\/ul>\n<\/div>\n\n\n\n
    \n
    \"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n

    To adjust pH, we use pH minus (pH\u2013) to lower it and pH plus (pH+) to raise it.<\/p>\n\n\n\n

    Note on chemical addition:
    For pools built with Piscinity technology, chemicals should not be added undiluted directly into the pool, as they can stain the membrane. The correct method is to add chemicals to the equipment basket or dissolve them in a bucket of warm water before dispersing around the pool.<\/p>\n\n\n\n

    Water Hardness<\/h2>\n\n\n\n

    High water hardness combined with high pH can lead to scale formation on pool surfaces. To minimize scaling, maintain pH around 7.2. For scale-free water, a water softener is recommended.<\/p>\n<\/div>\n<\/div>\n\n\n\n

    Water Disinfection<\/h2>\n\n\n\n

    Pathogenic microorganisms thrive under certain conditions, such as neutral pH, presence of organic matter, and nutrients like nitrogen and phosphorus. Because of their small size, microorganisms are difficult to remove completely through physical or chemical processes like sedimentation and filtration. Therefore, disinfection is essential to protect swimmers\u2019 health.<\/p>\n<\/div>\n\n\n\n

    \n
    \"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n

    Disinfection is the process of destroying or inactivating pathogenic microorganisms to ensure the water is safe for human use.<\/strong><\/p>\n\n\n\n

    A critical factor is the ability of the disinfectant to maintain a residual concentration in the circulation system to continuously protect public health.<\/p>\n\n\n\n
