11.3.4. SILIPHOS FILTER
Protects water systems in hotels, public buildings, private households and industry against scale
formation and corrosion. Prevents “brown” water and clogged pipes. Save energy and money.
Extends the life of water instillations.
Siliphos is a glassy polyphosphate containing silicate. The application is done by dispensers of variable
size. They require no electric installation and hardly any maintenance. They only have to be refilled
with spheres as consumed. Refiling is very easy.
What can SILIPHOS do for you?
Mostly natural waters cause damage in pipes, boilers and other instillations. Some contain dissolved
minerals, mainly calcium and magnesium salts. These types of water are called hard.
Hard water forms scale and corrosion in water systems. This leads to disadvantages and higher
energy demand. Clogged pipes may have to be replaced. Heating coils may overheat and fail.
Soft water is aggressive on metals and causes corrosion. Consequently, the tap water turns brown.
Leaks and burst pipes may be the result.
SILIPHOS prevents scale and stops corrosion. It utilizes the phenomenon that very low
concentrations of polyphosphates are sufficient to inhibit the disposition 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, even iron oxide and CaCO
3
layers to
some extent.
SILIPHOS consists of 100% active substance. The use in tap water and other types of fresh water
at the prescribed dosage is inoffensive. The recommended dosages are within the limits of the
German drinking water regulations (TrinkwV dated 21/05/2001)
The purity of SILIPHOS and SILIPHOS II for treatment of portable water is in accordance with the
existing Ec-Standard (EN 1208) as well as the requirements of the ‘FAO/WHO Expert Committee on
Food Additives” (7
th and 19 th Report). SILIPHOS II is also NSF listed since 1991 as “Drinking Water
Treatment Chemicals”
SILIPHOS SPHERES
A sparingly soluble glass – like polyphosphate – silicate combination of highest purity. SILIPHOS
dispensers should be refilled when 1/3 of the content is used up, normally only after approximately 3-
6 months. This depends on the individual instillation
.
