Siliphous ball



Silicon phosphor crystal is added to silicon phosphor crystal tank, and P2O5 is the chemical component of the agent. After the conversion of the dosing tank, the tap water with anti-corrosion and scale is exported. The treated tap water can directly provide water for industrial production and people’s life.


Siliphos is a kind of slow-released chemical agent. It is an economical products to prevent water system from

limescale and corrosion. It is made from food grade sodium polyphosphate and calcium oxide smelted under the high

temperature (1200℃-1700℃). Siliphos can react with Ca2+ & Mg2+ efficiently to make them soluble complex.

So it is an efficient antiscalant.  Our Siliphous also react with Fe2+ to create a insoluble film adhering on the surface

of the water pipe to protect pipe from corrosion. Blue Siliphos also have the performance of antibacteria and

algae removal.
