Hard Water Scale is Primarily Calcium and Magnesium, Are There Other Kinds of Scale?

What is Scale and the Known Types of Scale?

Scale is the precipitation of mineral deposits that are caused by soluble salts. The primary agents responsible are the carbonates and sulfates of calcium and magnesium with barium salts, silicate, and phosphate scaling. Mineral scale formation is a considerable issue in domestic, commercial, and industrial applications. The formation of mineral deposits is affected by several factors including supersaturation, temperature, pH, pressure, flow velocity, and the presence of impurities.

Different areas and processes, where equipment comes into contact with scaling water either with or without temperature gradient, are being affected by this problem; steam generators, cooling systems, membrane surfaces, and evaporators, just to name a few.

The main form of scale and most known to everyone is calcium carbonate, but it is not the only form of scale. Some other common forms of scale are calcium and barium sulfate, magnesium-based scales, silica scales, iron scales, calcium phosphate, and struvite. Please note that calcium sulfate and calcium chloride along with magnesium sulfate and magnesium chloride are considered permanent hardness, which do not precipitate out as temperature increases. That being said under extreme circumstances they will percipitate out.

When we speak of scale for the most part, we are referring to inorganic scale. Inorganic scale refers to dissolved minerals that are forced out of solution. This causes reaction between incompatible ions and changes the thermodynamic and equilibrium state of the source fluid. Supersaturation and subsequent deposition of the inorganic salts occur.

Some important terms to know:

Anhydrous – A substance that does not contain any water.

Elements – May exist in the native (uncombined) state, in which case their formulas are simply their chemical symbols: gold (Au), carbon (C) in its polymorphic form of diamond, and sulfur (S) are common examples.

Hydrothermal – When minerals are chemically precipitated from hot solutions within Earth.

Igneous (magmatic) – When minerals crystallize from a melt.

Triclinic – Denotes a crystal system or three-dimensional geometrical arrangement having three unequal oblique axes.

Sedimentary – When minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion.

Metamorphic – When new minerals form at the expense of earlier ones owing to the effects of changing -usually increasing – temperature or pressure or both on some existing rock type.

Monoclinic – Denotes a crystal system or three-dimensional geometric arrangement having three unequal axes of which one is at right angles to the other two.

Polymorphic – Occurs in different forms. Like calcium carbonate, vaterite, aragonite are all different forms CaCO3.

Hardness (H) – The resistance of a mineral to scratching. It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. This is not the same as water hardness. See chart below for the Mohs scale of hardness.

Is There An Effective Way To Deal With Scale Without Using Chemicals?

Yes, Hydropath technology that powers the HydroFLOW devices which are highly efficient, non-intrusive electronic descalers that are installed on the water pipe entering your home or business. It treats fluids by inducing a robust yet harmless signal of 150kHz throughout plumbing systems made of any material, including PEX and PVC.

These electric waves cause mineral ions to form suspended clusters that turn into stable crystals when temperature or pressure changes occur. The suspended crystals will prevent scale from building up in pipes and on heating elements, thus increasing heat transfer efficiency, lowering maintenance costs and reducing chemical usage. Standard applications include plumbing systems, heat exchangers, water heaters, boilers, cooling towers, belt filter presses, wells and pumps. Popular sectors include residential, commercial, industrial and agricultural.

Unlike other products that treat liquids at a single point in a system and whose impact starts to diminish immediately after that point, HydroFLOW provides continuous water conditioning – ensuring a consistent and ongoing effect. Also, due to its unique, non-intrusive design, HydroFLOW doesn’t add any chemicals to your water supply while inhibiting pipe corrosion and eradicating bacteria and algae.
