NettetIn the lime-softening process, the pH of the water being treated is raised sufficiently to precipitate calcium carbonate and, if necessary, magnesium hydroxide. The normal pH of water is between 6.5–8.5. In small systems, lime softening is typically practiced by adding hydrated lime to raw water to raise the pH to approximately 10. Nettet10. apr. 2024 · A common active treatment is lime neutralization, which involves lime precipitation that occurs in a high-density sludge process. A slurry of the lime substance is placed into a large tank that holds the acid mine drainage. The purpose of this technique is to increase the water’s pH to around 9.0. hornsby unit fire
