Used: hot water for apartments and heating systems Energygy® MWD is a solution to the problem of water stone, which significantly increases the service life of pipes and connected equipment (faucets, dishwashers, boilers, etc.).

Galvanic water treatment MWD (Mineral water doctor) works on the electrochemical principle, when water containing calcium salts, magnesium and other mineral compounds flows through the unit, the potential difference in water is 0.7-1 volts depending on the concentration of calcium and magnesium in the water (otherwise in other words) the total hardness of the water. As a result, free zinc ions, both cations and anions, are released into the water from the titanium-zinc anode.

Calcium (Ca + 2) dissolved in water, which is the main cause of sediment (lime) in pipelines and heat exchangers, is present in water in the form of calcium bicarbonate (Ca (HCO₃) ₂). (calcite).

Ca (HCO3) 2 → CaCO3 + H2O + CO2

Free carbon dioxide CO2 combines with zinc cations released from the anode (anode from our device Ti-Zn) to form zinc carbonate ZnCO3 (or medically useful minerals used in the manufacture of medicines and cosmetics). Calcite CaCO3, which crystallizes in the trigonal system, is converted to aragonite CaCO3, which crystallizes in the diamond system. Aragonite and calcite are the same calcium carbonate in terms of composition, meaning that water does not change the hardness of water in any way, only aragonite does not settle and is easily removed from pipes and heat exchangers, and free calcium (Ca + 2) binds to free zinc anion and is also easily removed from the water system. . Of course, this only happens when the galvanic water treatment device is manufactured correctly and has the correct design. Our product MWD- Mineral water doktor meets this condition. We also experimentally determined the consumption of our anodes in 1 m3 of water and based on this we developed the design of our product with replaceable electrodes for high water flows and high water consumption. Of course, if our products consisted only of titanium-zinc anodes, they would not work. Our product design also includes copper cathodes (containing 99.998% copper) and, unlike other water electroplating products, our cathode is not a product housing, it is housed in a harmless polypropylene housing, which is currently most widely used in the production of drinking water pipes. .

Calcium transported in the pipeline system in the form of aragonite creates a grinding effect on the sediments already present in the pipes due to water flow and increased turbulence due to plastic meshes placed between the cathode and the anode, and free zinc anions combine compounds are removed from the water supply system. Another positive effect is the change of the surface oxidized metal layer due to zinc reduction reactions, which prevents further oxidation (rusting) inside the pipelines.

Existing layers of rust and dross are constantly degraded in microscopic amounts and removed from the system in dissolved form. After removal of the deposit, a protective anti-corrosion layer gradually forms on the inner surface of the pipe. The electrons released from the zinc anode, which react with the rust to form a magnetite, increase the cathodic protection of the pipelines, resulting in the elimination of further corrosion of the system. The shelf life of the product depends on the hardness of the water, the concentration of CO2 in the water and the pH of the water. At very high hardness and water acidity below pH 6, the decomposition of the zinc anode will be faster, thus shortening the service life of the device.
