Polyphosphate Ball
Siliphos Polyphosphate Water Treatment Balls
Siliphos is a specially formulated polyphosphate-based water treatment compound that combines the benefits of silicates and polyphosphates. It is designed to protect water systems from corrosion, scale formation, and metal deposition while maintaining water quality.
Siliphos is widely used in domestic, commercial, and industrial applications where metal surfaces are exposed to water.
Product Application
Uses & Benefits
Prevents limescale buildup caused by calcium and magnesium ions.
Protects heating elements, pipes, and valves from corrosion.
Extends the service life of appliances such as coffee machines, water dispensers, ice makers, boilers, and dishwashers.
Improves efficiency of machines 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 crystallization into scale.
Film Formation: Forms a thin protective layer on metal surfaces, reducing corrosion risks.
Controlled Release: The spherical shape ensures slow, 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 (soluble complex)
Fe(OH)2 + Na2[Ca2(PO3)6] → FeCa2(PO3)6 + NaOH (insoluble membrane)
Magnesium ions react the same as calcium ions.
