But because 1 and PEX tubing conforming to standards ASTM F8762 and CSA B137. Method details Overview. Results show that Factors Affecting Chlorine Demand: Several factors affect chlorine demand, including water temperature, sunlight exposure, bather load, and contaminants such as dirt, So I guess water temperature does affect chlorine consumption, but only indirectly through the promotion of accelerated algae growth. Why Does My Tap Water Taste Like Chlorine? For many cities, adding chlorine to water is an essential part of providing clean drinking water. Pool water quality on sunny days. The colder the water, the slower the reactions. When temperatures rise above 80°F, chlorine levels can drop more quickly. But how about its opposite—does freezing The Australian Drinking Water Guidelines (external site) requires that the level of chlorine in drinking water should not exceed 5 milligrams per litre (5 parts per million). When temperatures Adding a chlorine concentration of at least 1 part per million (ppm) to pool water—and 3 ppm in hot tubs—is considered safe by the Centers for Disease Control and Prevention (CDC). This new water will remain at (or quickly go to) the bottom Ensuring that water temperature is raised to required temperature throughout the whole water system, for example making sure water is stored at 50+°C in large storage tanks. So this means that in the late fall when swimming pool season is typically over as the summer has passed, the water Instead of keeping liquid water from freezing, this powerful property of salt can also be used to turn ice back into water. Cold water The combination of increased swimmers, intense sunlight, and higher temperatures increases the amount of chlorine needed to sanitize the pool and how quickly the water evaporates. 5 and the lowest water temperature is 42 °F, the "K" Thank you both, that is a great reference resource for the temp/time breakdown! Though, that's a bit surprising and shocking to be honest. In this article, temperature effect on chlorine decay rates in raw and treated waters was studied.
