    Italian Made Siliphos - "Shard Type"

    What is SILIPHOS?

    SILIPHOS is an economical and reliable water treatment system for potable and industrial water. It consists of glass-like polyphosphate silicate spheres and dispensers of variable size.

    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.

    SILIPHOS will also slowly remove existing scale in old pipes if it consists of brown scale, i.e. iron oxide.

    Hard scale, i.e. calcium carbonate cannot so easily be removed by SILIPHOS. Here the advantage is again that SILIPHOS will prevent further scaling up.

    Experience shows that scale and corrosion are not only found in galvanized but also in copper pipes (see picture on page 3). Even in plastic pipes, one can find scale and deposits.

    As a rule of thumb, one can say that a 1mm scale on the heating coils of a boiler, increases the energy cost by 15%.SILIPHOS consists of 100% active substances.

    The use of tap water and other types of freshwater at the prescribed dosage is inoffensive. The components of SILIPHOS comply with FAO/WHO standards.

    Siliphos is typically a combination of two substances: 

    Soft waters are aggressive to metals and cause corrosion. Consequently, the tap water turns brown. Leaks and burst pipes may be the result.

    - Polyphosphate Crystals: These are primarily used to combat hardness in water by sequestering minerals that cause scale.

    - Sodium Silicate Crystals: These serve the dual purpose of providing corrosion protection and aiding in the precipitation of metals.


    What is the Difference between Siliphos "Balls" and Siliphos "Shards"?

    Typically Siliphos is available in the market in two forms, "balls" and "shards"(or "chips") 


    Siliphos "Balls" - (Find the siliphos "balls" at the following link: )

    Siliphos "Balls" are typically a combination of Polyphosphate and Sodium Silicate, mixed together at the factory and then formed into a "ball" shaped media. This mixing at the factory into a single media, does also reduce the cost of the siliphos balls. 

    The main benefits of the balls are that it's slightly easier to handle, slightly less messy, and easier to get a visual idea of when the media needs to be replaced. 

    There are several problems with the balls when compared to the "shard" type siliphos is that the balls have a much smaller surface area than the "shards", so the efficiency is lower. In other words at the same volume of "shards" to "ball" will more effectively dose the water with siliphos at the same flow rate. 

    As the polyphosphate and Sodium silicate are combined into a single media ball form, there is always a risk that the mixture amount in a batch of balls is not correct, which can lead to the siliphos not being as effective. In some cases we have seen this result in the siliphos balls, "melting" too quickly, leading to a large siliphos "chunk" forming at the bottom of a housing or shell. 


    Siliphos "Shards" 

    Siliphos "Shards" is a mixture of Polyphosphate crystals and sodium silicate crystals. These crystals are manufactured separately into their own "Shards" Crystals, and then the two types of crystals are mixed together in the factory before packaging. This mixing at the factory ensures that the measurement of Polyphosphate crystals to sodium silicate crystals is exactly the same in every kilo of siliphos. 

    The main benefit of the "shards" over the "ball" type siliphos is that the shard (or chip) form of the siliphos crystals means that they have a much larger surface area. This mean longer and more effective contact time with the water, which in turn increases the effectiveness of the siliphos to treating the water. 



    What can SILIPHOS do for you?

    Most natural waters cause damage in pipes, boilers and other installations. Some contain dissolved minerals, mainly calcium and magnesium salts. Such waters are referred to as being hard.

    Hard waters form scale in pipes and boilers. This leads to a decrease in water pressure and increased energy demand. Clogged pipes may have to be replaced. Heating coils may overheat and fail.


    Siliphos in Water Treatment

    1) What is Siliphos?

    Siliphos is a water treatment compound, a glass-like Polyphosphate containing Sodium, Calcium Magnesium and Silicate, formulated specifically for the treatment of water problems. It is shaped into unique spheres and packed in 25 kg cartons or 50 kg PE-drums.

    2) What will Siliphos do?

    Basically, it will do four things:
    It will prevent so-called ‘brown’ or ‘red’ water;
    It will stop corrosions of plumbing and bathroom fixtures;
    It will eliminate hardness scaling;
    It will save you considerable costs on plumbing and
    installation repairs;

    3) Does Siliphos remove hardness and iron
    from water?

    No, it is known as a sequestering agent. That is, it “ties up” hardness and renders it harmless. It prevents the formation of brown water caused by oxidation of the iron pipes.

    4) How does Siliphos prevent corrosion?

    It forms a thin protective layer on the inside of pipes and metal parts. This film or layer is microscopic in thickness and will not build-up with time.

    5) Is this compound dangerous or harmful
    to use?

    No. All components used in Siliphos are 100% pure food-grade materials.

    6) Will Siliphos change the taste of water?

    No. It is colorless, tasteless and odorless in the concentrations recommended for treatment. Coffee and tea might even taste better.

    7) How is Siliphos added to a water system?

    A dispenser is the most reliable, accurate and economical
    method of feeding it.

    8) How much of Siliphos should be used?

    The installation being protected must get 3 - 5 g Siliphos, that is 2 - 3 g  P2O5 in every cubic metre (220 UK gallons / 1000 Litres) of water.
