Sodium hexametaphosphate, also known as SHMP or sodium polyphosphate, is a white, crystalline powder that is highly soluble in water. It is derived from the polymerization of phosphoric acid and is widely used in various industrial applications, including water treatment. Sodium hexametaphosphate is an effective sequestering agent, capable of binding to metal ions and preventing their interference with water treatment processes. It helps to inhibit scale formation and corrosion in water systems by sequestering calcium, magnesium, and other metal ions. Its general characteristics are:
- Chemical Formula: (NaPO3)6
- Physical State: White crystalline powder
- Solubility: Highly soluble in water
- Taste: Odorless and tasteless
- pH: Alkaline substance with a pH above 7 in solution
- Density: Approximately 2.48 g/cm³
- Melting Point: Decomposes above 616 °C (1,141 °F)
- Odor: Odorless
Sodium Hexametaphosphate Uses in Water Treatment
Sodium hexametaphosphate (SHMP) is widely utilized in water treatment processes for its sequestering and dispersing properties. It acts as an effective scale and corrosion inhibitor, preventing the formation of mineral deposits and protecting water systems from the damaging effects of scale buildup. Sodium hexametaphosphate is commonly used in cooling towers, boilers, and water supply systems to maintain their efficiency and prolong their lifespan. It also aids in water softening by sequestering calcium and magnesium ions, minimizing their interference with the treatment process. Additionally, SHMP helps in the dispersion of suspended particles and impurities, enhancing the effectiveness of filtration and sedimentation. Its compatibility with other water treatment chemicals and ability to improve water quality make it a valuable component in various water treatment applications.
