When water is combined with carbon dioxide to form very weak carbonic acid, an even better solvent results. As water moves through soil and rock, it dissolves very small amounts of minerals and holds them in solution. Calcium and magnesium dissolved in water are the two most common minerals that make water "hard." The degree of hardness becomes greater as the calcium and magnesium content increases and is related to the concentration of multivalent cations dissolved in the water.
There are a couple of ways in treating/removing scale from water. The well known ways of removing scale are Siliphos, Evolet, Water Softeners and Chemical dosing systems.
Not all of these will work to remove scale in any water. Siliphos and Evolet will only work to a certain level of hardness. Should the hardness level be too high, a Water Softener and chemical dosing systems have to be used to treat water with very high levels of hardness.Read More
Siliphos is an economic and reliable water treatment media for potable and industrial water. It is a glassy polyphosphate containing silicate. The application is done by dispensers of variable size and can be installed in almost every water system. They require no electricity and hardly any maintenance. They only have to be refilled with spheres as consumed. Refilling is very easy..
Siliphos prevents scale and stops corrosion. It utilizes the phenomenon very low concentrations of polyphosphates that are sufficient to inhibit the deposition of scale onto metalic surfaces. Because of its phosphate ans silicate content siliphos also inhibits corrosion by forming a thin protective layer on the metal surface. A siliphos concentration of 2-3ppm is sufficient to achieve both of these effects.
Siliphos will 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.
