Polyphosphate Powder

Polyphosphate Powder

Polyphosphate Powder is a highly effective water treatment additive used for preventing scale formation, controlling corrosion, and reducing heavy metal contamination in both residential and industrial water systems. Made from food-grade or industrial-grade sodium polyphosphate, this powder is designed to dissolve gradually in water, releasing polyphosphate molecules that stabilize hardness minerals and protect plumbing systems.


  • Model number: AP-1(KDF-manlin polyphosphate beads)

Usage of Polyphosphate Antiscalant Powder

Polyphosphate antiscalant powder from our factory Kaidefei Fluid Technology is commonly used in household water purification and small equipment protection. It is often combined with activated carbon and pressed or filled into composite filter cartridges (commonly found in kitchen water purifiers, coffee machines, and pre-filters for water dispensers).

  • Activated carbon part → Adsorbs residual chlorine, odors, and organic matter, improving taste.

  • Polyphosphate part → Slowly dissolves with the water flow, releasing trace polyphosphate ions to provide scale inhibition and corrosion protection.

When a sintered carbon block and polyphosphate powder/crystals are combined, they deliver a dual function of purification + scale inhibition.

  • Sintered carbon block: Removes residual chlorine, odors, and part of the organic matter, improving taste.

  • Polyphosphate powder: Slowly releases polyphosphate to prevent calcium and magnesium scale, protecting heating elements and pipelines.

With this design, the user only needs a single filter cartridge to achieve both purification and scale inhibition. Compared with using separate carbon block and antiscalant filters, it is more compact and space-saving, making it especially suitable for small devices such as coffee machines, water dispensers, and water filter pitchers.

The polyphosphate powder acts as a powerful scale inhibitor by sequestering calcium and magnesium ions, which are the primary contributors to limescale formation. Through chelation, it prevents these minerals from precipitating and depositing on internal plumbing surfaces, heating elements, and appliances, thereby extending the lifespan and efficiency of water heaters, coffee machines, and other household or commercial equipment.
