The following are common pool water quality testing standards and their significance:<\/span><\/p>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">1. Turbidity<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Standard: Turbidity should be \u2264 0.5 NTU3 or \u2264 1 NTU.<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Significance: Excessive turbidity affects water clarity and increases the risk of spreading bacteria and viruses.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">2. pH<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Standard: pH should be maintained at 7.0 to 7.8.<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">SIGNIFICANCE: The proper pH helps the disinfectant to be effective while reducing skin and eye irritation.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">3. Free residual chlorine<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Standard: Free residual chlorine concentration should be maintained at 0.3~1.0mg\/L.<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">SIGNIFICANCE: Too low a free residual chlorine level reduces disinfection effectiveness, while too high a level may irritate the skin and respiratory tract.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">4. Urea content<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Standard: Urea content should be \u22643.5mg\/L.<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Significance: Excessive urea can lead to water contamination, which may cause respiratory discomfort, skin irritation and other problems.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">5. Total colony and coliform<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Standard: The total number of bacterial colonies should be less than 200CFU\/mL6 or 1000CFU\/mL, and coliforms should not be detected per 100mL.<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Significance: Controls the bacterial population and prevents the spread of disease.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">6. Water temperature<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Standard: Water temperature should be maintained at 23~30\u2103.<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Meaning: Appropriate water temperature provides a comfortable swimming experience and avoids discomfort caused by too high or too low water temperature.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">7. Oxidation reduction potential (ORP)<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Standard: ORP should not fall below specified values when using chlorine and ozone disinfection.<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Significance: ORP is an important indicator of the effectiveness of water disinfection.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">8. Ozone concentration<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Standard: Ozone concentration should not exceed 0.2mg\/m\u00b3 in the air 20cm above the water surface of the swimming pool and 0.05mg\/m\u00b3 in the pool water.<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Significance: Control ozone concentration to avoid health hazards to swimmers.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">9. Footbath chlorine residual<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Standard: The residual chlorine content of footbath water should be maintained at 5 to 10 mg\/L8.<\/span><\/li>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Significance: To ensure the effectiveness of disinfection of foot dipping pools and to prevent the spread of foot diseases8.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-family: helvetica, arial, sans-serif;\">10. Other indicators<\/span><\/h3>\n<ul>\n<li><span style=\"font-family: helvetica, arial, sans-serif;\">Such as cyanuric acid and hydrogen peroxide are also important references for pool water quality testing34.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-family: helvetica, arial, sans-serif;\">The above standards synthesize multiple sources to ensure safe pool water quality and provide swimmers with a healthy and comfortable swimming environment.<\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Swimming pool water quality testing standards is to ensure the safety of swimming pool water quality, to protect the health of swimmers is an important basis.
