Webb2 maj 2024 · The "neutral" zone of the Ryznar index is roughly around the numerical value 6. Generally, any value above 6 indicates that the water is likely to form a calcium carbonate scale. A value below the number 6 indicates that the water will dissolve calcium carbonate formations. The Ryznar index is calculated as follows: 2 x pH s - pH. where: Webb中文名. 朗格利尔饱和指数. 外文名.
