What is Scale and How does it Impact Water Treatment?
Published by James McDonald, PE, CWT, Technology and Marketing Manager at Chem-Aqua, Inc. in Technology
Hard water has been causing issues for humanity for ages, whether it is making it difficult to wash our clothes and cars, or depositing on our hot water heaters and kettles. Hardness scale is typically the combination of calcium and magnesium compounds that have precipitated out of water (e.g., calcium carbonate, magnesium silicate). This tough deposit forms in HVAC cooling systems and process water systems and can wreak havoc by decreasing system life and increasing energy usage, maintenance, and operational costs.

When the pH of water is greater than pHs ( saturation pH with respect to CaCO3,) the water cannot accomodate any more CaCO3 and it precipitates & gives up as deposits on the surface of pipes or the carrying medium of such water. Scale is thus formed. LSI value is positive.
