WebLSI is used to determine if your water supply has a presence of scale forming deposits (positve LSI) or corrosion conditions (low LSI). When your LSI is at 0.00 then it considered to be at its equilibrium, but the ideal range is usually between -0.30 and +0.30. WebA factor used to measure whether the right balance of carbonate species is produced for stabilisation of treated water is the Langelier Saturation Index (LSI). The Drinking Water Standards for New Zealand 2005 (Revised 2008) states that the correlation between the index and plumbosolvency is poor for some NZ waters and is slow cooker sausage recipes casserole

WebLSI = 0 - Water is considered to be saturated of CaCO 3; no CaCO 3 precipitation nor dissolution is expected, it is balanced. LSI 0 - Corrosive tendency, meaning CaC0 3 will dissolve in this water. The ideal LSI range is -0.3 to +0.3.

Calculating the Puckorius Scaling Index for water treatment

WebLSI determines if water is corrosive (under-saturated, low LSI), balanced, or scale-forming (over-saturated, high LSI). Commercial and industrial water treatment applications use the LSI as an objective measure of water balance. Cooling towers, waste water, drinking water, irrigation, you name it. The LSI is the unbiased truth. Web15 mrt. 2024 · MANTECH provides the ideal solution for determining the LSI of cooling water and other waters with the MT100 Analyzer.
