ALBA Siliphos
Protects water systems in hotels, public buildings, private households and industry against scale formation and corrosion prevents “brown” water and clogged pipes saves expensive repairs or even replacement of water pipes, boilers, heaters, cooling systems etc. Saves energy and money extends the life of water installations
What is ALBA Siliphos
ALBA Siliphos is an economic and reliable water treatment system for potable and industrial water. It is a glassy polyphosphate containing silicate. The application is done by dispensers of variable size.
ALBA Siliphos dispensers can be installed in almost every water system. They require no electric installation and hardly any maintenance. They only have to be refilled with spheres as consumed. Refilling is very easy.
What can ALBA Siliphos do for you?
Mostly natural waters cause damages in pipes, boilers and other installations. 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.
ALBA Siliphos prevents scale and stops corrosion. It utilizes the phenomenon that very low concentration of polyphosphates are sufficient to inhibit the deposition of scale onto metallic surfaces. Because of its phosphate and silicates content Alba Siliphos also inhibits corrosion by forming a thin protective layer on the metal surface. Alba Siliphos concentration of 2-3 ppm is sufficient to achieve both of these effects.
ALBA Siliphos also slowly remove existing scale in old pipes, even iron oxide and CaCO3 Layers to some extent. Experience Shows that scale and corrosion is not only found in galvanized but also in copper pipes. Even in plastic pipes one can find scale and deposits .
As a rule of thumb one can say that 1mm scale on the heating coils of a boiler increases the energy cost by 15%. ALBA Siliphos Consists of 100% active substance. The use in tap water and other types of fresh water at the prescribed dosage in inoffensive. The recommended dosages are within the limits of the German drinking water regulations.
The purity os ALBA Siliphos and ALBA Siliphos II for the treatment of potable water is in accordance with the existing EC-Standard as well as the requirements of the “FAO/WHO Expert Committee on Food Additives” (7th and 19th Report). ALBA Siliphos ii is also NSF listed since 1991 as “Driniking Water Treatment Chemicals”.
The ALBA Siliphos System:
1. ALBA Siliphos spheres: A Sparingly soluble glass-like polyphos- phlate-silicate combination of highest purity.
2. ALBA Siliphos Dispensers: The Dispensers are installed in the water systems and filled with the ALBA Siliphos spheres. The tap water flows through the dispensers and dissolves very low quantities oa ployphos-phases.
ALBA siliphos dispensers do not cause a critical pressure drop in the water pipes. Alba Siliphos dispensers are manufactured from a highly resistant plastic material. The cap is reinforced fibre glass. Sizes are available from 0.5 kg up to a capacity of 5 kg. Bigger dispensers up to a capacity of 200 kg ALBA Siliphos are made of welded steel. All manufactured dispensers must be approved by Albario Hawk eye.
Correct Dosing
The size of the dispenser depends on the average water consumption per hour. The following range of dispenser sizes is available to cater for the widely varying needs of our customers.
The recommendations result from practical experience and refer to cases of intermittent water consumption as is the case with most users of potable water e.g. Hotels, hospitals and private homes. It is important to calculate the sizes of the dispensers to the average water consumption-not to the peak demands.
ALBA Siliphos dispensers should be reffilled when 1/3 of the content is used up, normally only after appr. 3-6 months. This depends on the individual installation.
ALBA Siliphos Systems have been installed with great success in private houses, hotels office buildings, schools and hospitals for the treatment of potable water. They are also applied in small and medium sized industrial estates for the treatment of cooling systems, autoclaves, machine cooling ets.
How to install the dispenser
The opposite picture shows a 3 kg installed dispenser with a bypass. The solubility of the ALBA Siliphos spheres is designed for cold O water (5-3 C). The dispenser has to be installed in a cool place (e.g. Basement) after the water meter and filter, away from heat sources that could warm it up when no water is flowing. It is also advisable to fit the dispenser with a bypass line for maintenance or toe be drained for refill. The operating pressure of the plastic dispensers should not exceed 8 bar.
Advice on water Treatment
The above is based upon practical experience and reflects the state of the art. The uniform quality of the materials we deliver is included in our guarantee.
The product described has a definite spectrum of activity. The water composition or technical factors of manufacturing circumstances can produce conditions, which do not lie within this spectrum. If you explain your problems to us, we can certainly offer you solution. Is could be that your conditions make it advisable to use a product of quite different type.
We also recommend the use of ALBA Siliphos Together with water softeners after blending with raw water because softened water will cause corrosion.
ALBA Siliphos dispensers should be drained in case of long stagnation periods (3months). ALBA Siliphos is allowed up to 5 ppm P2 5 O 4 or 6.7 ppm Po in potable water in most countries of the world.
ALBA Siliphos can be determined by normal P O /PO colorimetric analyses of phosphorus.
