What Is Calcium Bicarbonate? |
Calcium bicarbonate is also the primary source of minerals for the formation of stalactites, stalagmites and columns seen within caves. As water containing carbon dioxide passes through limestone, it dissolves some of the calcium carbonate over time and becomes richer in bicarbonate composition.

Lime (calcium carbonate) Maintenance of Microirrigation ...
Precipitation of calcium carbonate (lime) is a common clogging problem in microirrigation systems. Water with a pH of or higher and a bicarbonate level of at least 2 meq/l (120 ppm) is susceptible to calcium carbonate precipitation if comparable levels of calcium are present naturally in the system or if a compound that contains calcium is injected into the system.

Sodium Carbonate an overview | ScienceDirect Topics
Oct 03, 2010· Lime, sodium carbonate (soda ash), and/or sodium hydroxide (caustic soda) are added to water to convert soluble calcium and magnesium hardness to insoluble calcium carbonate and magnesium hydroxide in a contact vessel for 60–90 min [10, 12, 14]. Lime is not a true coagulant but reacts with bicarbonate alkalinity to precipitate calcium carbonate.
