Polyphosphate Ball
Product Description
Polyphosphate antiscalant balls are specialized water treatment media made from food-grade polyphosphate. They prevent scale formation and corrosion in appliances and water systems. When dissolved at a controlled rate, they release trace polyphosphate ions, providing long-lasting protection for household and commercial equipment.
Product Application
Uses & Benefits
Prevents limescale buildup caused by calcium and magnesium ions.
Protects heating elements, pipes, and valves from corrosion.
Extends service life of appliances such as coffee machines, water dispensers, ice makers, boilers, and dishwashers.
Improves machine efficiency by maintaining clean water flow paths.
Cost-effective and easy to maintain – simply replace or refill when consumed.
How Does It Work?
The balls dissolve gradually in flowing water, releasing a controlled amount of polyphosphate into the system.
Sequestration: Polyphosphate binds to calcium and magnesium ions, preventing them from crystallizing into scale.
Film Formation: A thin protective layer forms on metal surfaces, reducing corrosion risk.
Controlled Release: The spherical shape ensures slow and stable dissolution for long-term effectiveness.
Representative Chemical Reactions
Na2[Na4(PO3)6] + CaX → Na2[Na2Ca(PO3)6] + NaX
Na2[Na2Ca(PO3)6] + CaX → Na2[Ca2(PO3)6] + Na2X
Fe(OH)2 + Na2[Ca2(PO3)6] → FeCa2(PO3)6 + NaOH
Note: Magnesium ions react similarly to calcium ions.

Chemical Structure and Forms
Polyphosphates from our factory Kaidefei Fluid Technology are polymers made up of repeating phosphate (PO4) units linked together. They can be linear chains or cyclic (ring) structures, unlike orthophosphates which contain only one phosphate group.
Biological Roles
Energy Storage: Polyphosphates (ATP, ADP) are vital for cellular energy storage and transfer.
Cellular Processes: Involved in gene regulation, protein synthesis, and lipid synthesis.
Stress Response: Help cells cope with oxidative stress by acting as chaperones and regulating pathways.
Blood Clotting: Influence clotting and inflammation.
Other Roles: Support bacterial growth, virulence, and biofilm formation.
Applications
Water Treatment: Controls corrosion, scale, iron, and manganese in water systems.
Food Additives (E452): Improve texture, moisture, and stability in foods.
Flame Retardants: Used in wood, paper, fabric, and plastics.
Fertilizers: Ammonium polyphosphate is a phosphorus source for plants.
Research: Widely applied in microbiology and biochemical studies.
The ultimate solution for protecting industrial and drinking-water systems from limescale, calcium deposits, and corrosion—delivering professional performance without compromise.
💧 Key Advantages
Ultra-high descaling efficiency (up to 98%) — Food-grade raw materials, sintered at high temperature, release polyphosphate crystals to prevent scale buildup.
Safe and certified — Compliant with NSF, FDA, REACH, RoHS, CE, and ISO standards.
Slow-release & long-lasting — Beads remain stable until water flow activates dissolution, lasting 1–2 years with only 3–12 month replacement.
Effortless Use & Broad Compatibility
No salt, no electricity required — Easy installation with dispensers.
Versatile application — Works in hot/cold systems: boilers, RO, washing machines, heat exchangers.
Residential & industrial use — Suitable for both home appliances and large-scale systems.
Cost-Effective & Eco-Friendly
Reduces maintenance & extends equipment life — Prevents blockages, lowers repair costs.
Boosts energy efficiency — Cleaner heat exchangers save energy and reduce CO₂ footprint.
Backed by 20 years of R&D — Proven performance by AquaVow.
