WHAT IS HARD WATER?
Almost everyone has heard of the term "hard water," and many of us have experienced the annoyance that comes with having mineral-rich water flowing into our homes. While this type of water is not harmful to consume, a hard water scale can have a negative impact on your home's plumbing and appliances over time.
WHAT IS SCALE?
Scale is the result of the precipitation of mineral deposits caused by soluble salts. The primary agents are calcium and magnesium carbonates and sulphates with barium salts, silicate and phosphate scaling. Mineral scale formation is a significant problem in residential, commercial, and industrial applications. Several factors influence the formation of mineral deposits, including supersaturation, temperature, pH, pressure, flow velocity, and the presence of impurities.
This problem affects a variety of areas and processes where equipment comes into contact with scaling water, either with or without a temperature gradient; for example, steam generators, cooling systems, membrane surfaces, and evaporators, to name a few. Calcium carbonate is the most common and well-known type of scale, but it is not the only type of scale.
Most of the time, when we talk about scale, we're talking about inorganic scale. Dissolved minerals that are forced out of solution are referred to as inorganic scale. This causes incompatible ions to react, altering the thermodynamic and equilibrium state of the source fluid. Supersaturation occurs, followed by the deposition of inorganic salts.
WHAT ARE SOME OF TYPES OF SCALES
Limescale is a hard, chalky deposit that is primarily composed of calcium carbonate (CaCO3). It frequently accumulates inside kettles, boilers, and pipework, particularly hot water pipework.
The lower pressure mid-temperature polymorph is a trimorphic with kyanite and sillimanite. Andalusite may convert to sillimanite at higher temperatures and pressures. As with its other polymorphs, andalusite is an aluminosilicate index mineral, providing information about the depth and pressures involved in the formation of the host rock.
The inorganic compound barium sulphate (or sulphate) has the chemical formula BaSO4. It is a white crystalline solid that is odourless and water insoluble. It occurs naturally as the mineral barite, which is the primary commercial source of barium and materials derived from it.
A mineral that forms rocks. It is extremely common and can be found in sedimentary, metamorphic, and igneous rocks all over the world. Some geologists consider it a "ubiquitous mineral," meaning it can be found anywhere. Calcite is the main component of limestone and marble.
Mg(OH)2 is the chemical formula for an inorganic compound. It can be found in nature as the mineral brucite. It is a white solid with a low water solubility (KSP = 5.611012). Magnesium hydroxide is a common component of antacids and laxatives, such as milk of magnesia.
Is There Any Effective Way To Deal With Scale Without Using Chemicals?
NETSOL technology that drives the NETSOL devices, which are highly efficient, non-intrusive electronic de-scalers installed on the water pipe entering your home or business.
When temperature or pressure changes, these electric waves cause mineral ions to form suspended clusters, which then solidify into stable crystals. The suspended crystals will keep scale from forming in pipes and on heating elements, increasing heat transfer efficiency, lowering maintenance costs, and lowering chemical usage. Plumbing systems, heat exchangers, water heaters, boilers, cooling towers, belt filter presses, wells, and pumps are common applications. Residential, commercial, industrial, and agricultural sectors are all popular.
