Calcium Carbonate CaC03 Cartridges

Calcium carbonate (CaC03) is a common compound found in nature, including in water sources. However, using calcium carbonate as a filter media in water filter cartridges is less common compared to other filtration methods and is important to note that calcium carbonate is not typically used as a standalone filter media for removing contaminates from water. Instead, it’s more regularly used in water treatment processes to address certain water quality issues such as, adjustment of the pH scale, especially in water that is too acidic acting as a natural alkalizing buffer, helping to raise the pH levels. They have great capabilities in reducing the water hardness by precipitating calcium and magnesium ions, which are responsible for water hardness. This process is known as “Calcite precipitating” and is often used in water softening systems, which aids in reducing the corrosiveness of water, especially in systems that have tendency to leach metals from pipes and plumbing fixtures and fittings. When calcium carbonate is used in combination with other chemicals or equipment, it is known to help prevent the formation of scale in pipes and appliances due to the presence of calcium and carbonate ions.
