Langelier Index Calculation As an example, suppose the drinking water supplied to animals has the following analysis. The LSI index is calculated at two temperatures: 25 o C (room temperature) and 82 o C (cage wash cycle).
Langelier and Aggressive Indices Page 1 ex langagg. fm. Langelier and Aggressive Indices Method 8073. Langelier Saturation Index. The Langelier Saturation Index (LI), a measure of a solutions ability to dissolve or deposit calcium carbonate, is often used as an indicator of the corrosivity of water. Langelier Index The Langelier Index is an approximate indicator of the degree of saturation of calcium carbonate in water. It is calculated (58 KB) using the pH, alkalinity, calcium concentration, total dissolved solids, and water temperature of a water sample collected at the tap.langelier index calculation example Calculated Langlier Index Langlier Saturation Index Calculation Sheet Test Results A tolerance of 0. 3 to 0. 3 is the ideal range for swimming pools A tolerance of 0. 5 to 0. 5 is acceptable for swimming pools A Saturation Index of higher than 0. 5 indicates carbonate scale formation. A Saturation Index of lower than 0. 5 indicates corrosive water.
