SILIPHOS prevents scale and stops corrosion. It utilizes the phenomenon that minute concentrations of polyphosphates are sufficient to inhibit the deposition of scale onto metallic surfaces. Because of its phosphate and silicate content, SILIPHOS also inhibits corrosion by forming a thin protective layer on the metal surface. A SILIPHOS concentration of 2-3 ppm is sufficient to achieve both of these effects.

What Is Siliphos Polyphosphate Media?

Siliphos polyphosphate media is a food-grade, granular additive designed to protect plumbing systems from corrosion and rust. When water flows over the media, it releases polyphosphates that form a thin, invisible protective layer inside pipes and tanks. This coating prevents iron, steel, and other metal surfaces from oxidizing, reducing rust, and extending the life of water systems.

Unlike traditional water softeners, Siliphos polyphosphate media does not remove hardness minerals or existing scale. Instead, it prevents new rust formation while allowing minerals like calcium and magnesium to remain in solution.

Key Features

  • Protects metal surfaces: Forms a thin, protective layer inside pipes, boilers, and tanks.
  • No chemicals or salt required: Safe for drinking water systems.
  • Low maintenance: Simply place the beads in a housing and replace them every few months.
  • Food-grade material: Suitable for potable water systems.
  • Compatible with hot and cold water: Effective up to ~80°C.

Technical Specifications

  • Appearance: Transparent glass-like beads
  • Polyphosphate content (as P₂O₅): ~61–67%
  • pH range: 6.0–7.5
  • Solubility: Slowly dissolving under flow conditions
  • Operating temperature: Up to 80°C
  • Recommended concentration: ~2–3 ppm in water
  • Media lifetime: 3–6 months, depending on flow rate

Benefits

  1. Corrosion Prevention: Protects pipes and appliances from rust.
  2. Maintains Water Quality: Minerals stay in solution; no chemical taste is added.
  3. Extends Equipment Life: Reduces maintenance costs for boilers, geysers, and water heaters.
  4. Simple Installation: Place media in a filter housing or dedicated cartridge.

Ideal Applications

  • Residential and commercial plumbing systems
  • Hot water systems (geysers, boilers)
  • Reverse osmosis pre-treatment
  • Solar water heating systems
  • Appliances such as kettles, coffee machines, and shower systems

Usage & Maintenance

  • Install Siliphos polyphosphate media in a suitable filter housing with proper water contact.
  • Refill or replace media every 3–6 months, depending on water hardness and flow.
  • Avoid using it in highly acidic water to prevent accelerated dissolution.
  • Periodically check for any changes in water quality or bead condition.
