Sodium Citrate Uses in Water Treatment
Sodium citrate plays several important roles in water treatment processes. It serves as a chelating agent, helping to bind and remove certain metal ions, particularly calcium and magnesium, which can cause scaling and interfere with the efficiency of water treatment chemicals. Sodium citrate is used in water softening applications to prevent scale formation and enhance the removal of hardness minerals. It also acts as a pH regulator, helping to stabilize and control the acidity or alkalinity of water. Sodium citrate is utilized in specific water treatment systems, such as cooling towers and boilers, to mitigate the negative effects of scaling and improve overall water quality. Its compatibility with other water treatment chemicals and its ability to effectively chelate and control pH make it a valuable component in water treatment processes.
