[0002] The hardness index of water quality is extremely harmful in industrial production. It mainly forms precipitates by the combination of calcium ions and magnesium ions (cations) with carbonate ions, sulfate ions, chloride ions and other anions in water, such as scale formed by precipitates such as carbonates, sulfates, and chlorides. This will cause pipeline system blockage, uneven heating and cooling in the heat exchange system, distortion of instrument probes, and under-scale corrosion of the equipment body. According to the impact of the above hardness on industry, production and life, there are also various technologies and process devices for water hardness removal in the current environmental protection market, such as electrochemical methods, ion exchange methods, lime softening methods, etc. to remove the hardness in water. Among them, the lime softening method for hardness removal is more widely used.

[0003] Traditional lime method for hardness removal: By adding slaked lime to water, calcium ions and magnesium ions in the water react with it to produce calcium carbonate and magnesium hydroxide precipitates.
