• Water Treatment Descaling and Corrosion Control Additives

CAC (Calcium Aluminate Cement)

• CAC (Calcium Aluminate Cement) is a specialty cement that is sometimes used in water treatment for lime removal. Lime (calcium hydroxide, Ca(OH)2) is a common byproduct of many water treatment processes and can cause scaling and corrosion in pipes and equipment. Lime removal is necessary to maintain the proper pH and prevent the buildup of calcium deposits in water treatment systems.

  CAC cement can be used in lime removal processes by adding them to the water to neutralize excess lime. This reaction forms calcium carbonate (CaCO3), a solid that can be separated from the water by sedimentation or filtration. However, it is important to note that CAC is a specialty cement, and its use for lime removal is not common.

  Other, more commonly used lime removal methods include adding acid to neutralize excess lime and using ion exchange resin systems to remove calcium ions from the water. The choice of method depends on the specific water treatment system and the desired results.
