WebbCORROSIVITY INDEX CALCULATIONS The Corrosivity Index (Langelier’s Saturation) is used to determine whether a water supply will support and deposit calcium carbonate. This deposit acts as a buffer against leaching of various metals within the distribution system; the primary concern of which is lead. WebbThe Langelier Index is an approximate indicator of the degree of saturation of calcium carbonate in water. It is calculated using the pH, alkalinity, calcium concentration, total …

WebbThe Langelier index is a popular way of expressing the equilibrium state of a solution in respect to calcite (Langelier, 1936) and is given by: ... The PSI index is calculated in a manner similar to the Ryznar Stability Index, described above, except that it incorporates the equilibrium pH and is calculated as follows: Webb17 juli 2024 · 1.1 This practice covers the calculation and adjustment of the Langelier saturation index for the concentrate stream of a reverse osmosis (RO) device. This … WebbOn the condition that there is a carbonate ion in water you can calculate the pH value of such water using the following equation: рН=10,328+lg (CO3/НСО3) (3) where, 10,328-negative logarithm of the dissociation constant of carbon dioxide in the second stage; CO3, HCO3-concentration of carbonate and bicarbonate, mol/l. gynecare thermachoice uterine balloon therapy
